Detailed Description
Exemplary embodiments of the present application are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present application to facilitate understanding, and should be considered as merely exemplary. Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
First embodiment
Fig. 1 is a flowchart of a volume configuration method according to a first embodiment of the present application, where the present embodiment is applicable to a case of performing volume configuration on a device to be configured, and the volume configuration may be performed before the device leaves the factory, or may be performed during a use stage of a consumer user. The method may be performed by a volume configuring means implemented in software and/or hardware, preferably in an electronic device to be configured having audio playback functionality. As shown in fig. 1, the method specifically includes the following steps:
s110, acquiring the total number of scales of the equipment to be configured and the current scale to be configured.
In the specific embodiment of the present application, the device to be configured may refer to any smart device capable of playing audio, such as a smart speaker, a mobile phone, or a television. Based on the hardware structure of the device to be configured, the device to be configured has a lowest audio playing decibel and a highest audio playing decibel, and the lowest audio playing decibel is smaller than or equal to the highest audio playing decibel. In order to facilitate the adjustment of the volume of the device between the lowest audio playing db and the highest audio playing db, a certain total number of scales is preset for the device according to the requirement, and under the condition of the total number of scales, the audio playing volume is changed along with the switching of the volume scales.
The total number of scales of the equipment to be configured can be uniformly set when the equipment leaves a factory, and can be customized according to requirements when a user uses the equipment. Correspondingly, the total number of the scales of the equipment to be configured and the current scale to be configured can be directly obtained according to the equipment configuration attribute, and the total number of the scales of the equipment to be configured and the current scale to be configured can be obtained in response to the adjustment operation of the user. When the volume of the equipment to be configured is configured, each volume scale of the equipment to be configured is configured independently, so that one volume scale currently being configured is the current scale to be configured. The current scale to be configured can be one or a plurality of scales to be configured independently, or all the scales can be configured one by one.
For example, when the equipment is factory set, setting the total number of scales of the equipment to be configured to be 10, namely, the equipment comprises 10 scales to be configured in total, wherein the scale 1 can represent the lowest audio playing decibel, and the scale 10 represents the highest audio playing decibel; or 10 scales are included from 0 to 9, wherein the scale 0 can represent silence and the scale 9 represents highest audio playing decibels. For another example, when the user uses the device, if the user perceives the volume change between the volume scales in an auditory manner to be insignificant, the total number of scales of the device to be configured can be adjusted to be reduced by 5, so that the volume change degree between the volume scales is increased within the range of the lowest audio playing decibel and the highest audio playing decibel.
S120, based on the sound pressure level sample set, determining a sound pressure level value corresponding to the current scale to be configured according to the total number of scales and the current scale to be configured.
In a specific embodiment of the present application, the sound pressure level sample set characterizes a correspondence between the device volume scale and the auditory perception sound pressure level. Wherein, the device volume scale refers to each single volume scale which is preset, such as scale 1, scale 2 and the like; the auditory perception sound pressure level refers to a sound pressure level value determined based on artificial experience auditory perception, for example, the sound pressure level value of the scale 1 is determined to be 30dB in auditory perception, and correspondingly, the sound pressure level sample set characterizes the corresponding relation between the scale 1 and the auditory perception sound pressure level of 30 dB. Specifically, the sound pressure level sample set may refer to sound pressure level sample values that are collected in advance, and that are uniformly changed in loudness between volume scales determined based on a certain total number of scales and subjective auditory perception based on human experience. Namely, under the condition that the sound pressure level sample set comprises at least one total number of scales, the corresponding relation between each volume scale and the sound pressure level value is formed.
The method comprises the steps of collecting various intelligent devices with audio playing functions in advance, collecting the total number of scales of the various intelligent devices, testing to obtain sound pressure level values of each volume scale in an actual environment, and establishing a corresponding relation among the total number of scales, a single volume scale and the corresponding sound pressure level values, so that a sound pressure level sample set is obtained.
In addition, an experimental environment can be constructed in advance, and a sound pressure level sample set can be obtained through testing of a plurality of subjects with normal hearing in the experimental environment. Exemplary, experimental site conditions are: determining the distance between the subject and the sound source and the sound box under a certain environment noise floor condition, such as 33-35 dB; the experimental tool is as follows: in a control platform prepared in advance, a certain volume change range is provided for a subject, for example, 0-207 is provided with 208 scales altogether, scale 0 is taken as silence, along with the gradual increase of volume scales, the audio frequency decibel corresponding to the volume scale is increased by 0.5dB, the minimum degree of volume change which can be perceived by human hearing is taken as a unit, for example, 2dB, and the sound box is controlled to carry out volume adjustment in the process of playing audio frequency by taking 4 scales as a unit. Therefore, aiming at the audio playable decibel value range of the test equipment and the preset total number of scales, the sound pressure level value corresponding to each scale to be configured is configured by the test subject, wherein the sound pressure level value is the uniform change of loudness of the test subject in auditory perception under the condition of the total number of scales.
For example, the scales 0-207 in the control platform correspond to audio playing dB values of 0dB-103.5dB, respectively, assuming that the audio playing dB value range of the test device is 0dB-90dB, and assuming that the total number of predetermined scales is 8. The sound pressure level value corresponding to the scale 0 is 0dB, the adjustment is performed within the range of scales 0-180 in the control platform, the sound pressure level value corresponding to the scale 1 is uniformly set to be close to the sound pressure level value corresponding to the scale 71 in the control platform based on the auditory perception of the volume loudness corresponding to each of the scales 0dB-90dB, the sound pressure level value corresponding to the scale 2 is close to the scale 96 in the control platform, and the like, and the volume adjustment graph with the total number of scales being 8 is obtained based on the auditory perception and is repeatedly adjusted, as shown in fig. 2. Similarly, a volume adjustment graph with a total of 10 scales can be obtained, as shown in fig. 3.
In this embodiment, in view of the corresponding relationship between the volume scales of the device in the sound pressure level sample set and the auditory perception sound pressure level, the loudness between the volume scales determined based on auditory perception is uniformly changed, so that the sound pressure level value corresponding to each scale to be configured is determined from the corresponding relationship according to the total number of scales of the device to be configured and the current scale to be configured based on the corresponding relationship between the volume scales in the sound pressure level sample set and the auditory perception sound pressure level.
Illustratively, curve fitting is performed based on a sound pressure level sample set to obtain a sound pressure level fitting curve capable of representing the corresponding relation between the volume scale and the auditory perception sound pressure level, and a sound pressure level value corresponding to the scale to be configured is calculated according to the sound pressure level fitting curve. The sound pressure level fitting curve can be expressed by adopting an equation, the total number of the scales and the current scale to be configured are taken as independent variables, the sound pressure level value corresponding to the current scale to be configured is taken as a dependent variable, and therefore the total number of the scales and the current scale to be configured are substituted into the equation for calculation, and the sound pressure level value corresponding to the current scale to be configured is obtained through solving.
It should be noted that, according to the volume adjustment curves in fig. 2 and 3, under the condition of uniform loudness change determined based on auditory perception, the volume adjustment curve is a nonlinear function, and according to the trend of the curve, the volume adjustment curve more conforms to a logarithmic equation, so that the logarithmic equation can be used to represent a sound pressure level fitting curve. Specifically, the volume scales of the test equipment with different total scales can be normalized according to the total scales of the test equipment, sound pressure level values corresponding to the volume scales after the normalization of the test equipment with different total scales are combined, a volume adjustment scatter diagram is drawn according to the normalized volume scales and the sound pressure level values combined on the normalized volume scales, a curve type is determined according to the volume adjustment scatter diagram, curve fitting is performed according to the curve type, and a quantity configuration logarithmic equation is obtained. The sound pressure level fitting curve can be represented by the following volume configuration logarithmic equation: y= aln (x/k) +b; wherein k represents the total number of scales, and the value range is an integer in [1, + ]; x represents the current scale to be configured, and the value range is an integer in [0, k ] or [1, k ]; y represents the sound pressure level of the scale to be configured currently; a and b represent constants.
Further, after determining the volume configuration log equation, at least one of a goodness of fit, an equation saliency, and a residual distribution of the volume configuration log equation may be determined to verify the volume configuration log equation. The sound pressure level value of the equipment to be configured in practical application can be configured, and the automatic volume configuration effect of the logarithmic equation is configured through subjective auditory perception.
Because the technical means of taking the sound pressure level value corresponding to each scale based on the uniform change of the loudness on the auditory perception of the human ear as a sample is adopted, the technical problem that the actual auditory experience of the user is poor after the volume configuration is overcome, and the technical effect of improving the auditory experience brought by the actual volume adjustment of the user is further achieved.
S130, according to the determined sound pressure level value, carrying out volume configuration on the equipment to be configured.
In a specific embodiment of the present application, after determining the sound pressure level value corresponding to the current scale to be configured, the volume configuration of the current scale to be dubbed may be adjusted based on the system software, so that the audio decibel played under the current scale to be dubbed meets the determined sound pressure level value. For example, a total of 208 graduations of 0-207 are preset in the system, each graduation being incremented by 0.5dB. If the sound pressure level corresponding to the current scale to be configured is 42dB, the volume mode of the preset scale 84 corresponding to 42dB is equivalently configured as the volume mode of the current scale to be configured, so that the volume configuration of the equipment to be configured is realized.
Based on the volume configuration mode of the embodiment, different intelligent devices can be scientifically and uniformly configured based on the sound pressure level sample set, a volume configuration result that the loudness on subjective auditory perception is uniformly changed is obtained, and then the same auditory experience can be obtained when a user initiates the same control instruction on different intelligent devices. For example, based on the same volume adjustment command "loud click" of the user, the control result that the volume change between some device scales is too obvious and the volume change between some setting scales is too gentle will not be generated, so that the user can perform uniform control between different devices based on the same volume adjustment command.
In this embodiment, the configuration process of the volume may be unified configuration before the device to be configured leaves the factory, and in the use process of the device, personalized volume configuration may also be performed according to the user requirement. For example, the total number of scales after the user adjustment may be determined in response to the user adjustment operation on the total number of scales, and the sound pressure level value of each volume scale may be updated according to the adjusted total number of scales based on the sound pressure level sample set. For example, the elderly is insensitive to sound variations, and the total number of scales of the device can be reduced appropriately according to user settings so that the resulting loudness between the volume scales varies to a greater extent. In addition, the method can also determine the adjusted volume scale and the sound pressure level value adjusted by the volume scale in response to the adjustment operation of the user on the sound pressure level value of at least one volume scale, determine a user-defined sound pressure level sample set according to the adjusted volume scale and the sound pressure level value adjusted by the volume scale, and update the sound pressure level value of each volume scale based on the user-defined sound pressure level sample set. For example, the user performs fine adjustment on the sound pressure level value corresponding to the common scale, and the value after user adjustment can be used as a sample to be supplemented in the sound pressure level sample set, or a user-defined sound pressure level sample set is generated, so that personalized sound pressure level configuration of the user is performed based on the updated sound pressure level sample set.
According to the technical scheme, through the sound pressure level sample set capable of representing the corresponding relation between the volume scale of the equipment and the auditory perception sound pressure level, the sound pressure level value corresponding to the current scale to be configured in the equipment to be configured with the known total number of scales is determined based on the sound pressure level sample set, so that the volume configuration of the equipment to be configured is carried out according to the determined sound pressure level value. The collection cost of the sound pressure level sample set is low, and based on big data sample processing, the influence of manual intervention and manual subjective experience in volume configuration is avoided, the technical problems of unscientific volume configuration and uneven price of scale adjustment loudness change are overcome, and further the technical effects of improving the hearing experience brought by actual volume adjustment of a user, improving the scientificity, accuracy and efficiency of volume configuration in equipment are achieved, and the volume configuration cost of the equipment is reduced.
Second embodiment
Fig. 4 is a flowchart of a volume configuration method according to a second embodiment of the present application, where, based on the first embodiment, the sound pressure level sample set is further explained, and according to the total number of scales and the currently to-be-configured scale, the sound pressure level value corresponding to the currently to-be-configured scale is determined, and the sound pressure level value corresponding to the currently to-be-configured scale can be determined according to the sound pressure level fitting curve obtained by performing curve fitting on the sound pressure level sample set. As shown in fig. 4, the method specifically includes the following steps:
S410, obtaining the total number of scales of the equipment to be configured and the current scale to be configured.
S420, calculating and determining a sound pressure level value corresponding to the current scale to be configured according to the sound pressure level fitting curve, the total number of scales and the current scale to be configured; the sound pressure level fitting curve is determined based on the sound pressure level sample set.
In a specific embodiment of the present application, in view of the association between each volume scale and a sound pressure level value when the sound pressure level sample set includes at least one total number of scales, the sound pressure level value is a decibel value that the loudness between each volume scale determined based on auditory perception is uniformly changed. And furthermore, in order to unify configuration standards under the condition of different total scales, the normalization processing of volume scales is carried out according to the total scales. And combining sound pressure level values after the volume scale normalization processing under the condition of different total scales. And drawing a volume adjustment scatter diagram by taking the abscissa as the normalized volume scale and the ordinate as the sound pressure level value corresponding to each normalized volume scale.
Illustratively, under the condition that the total number of scales is 8, the sound pressure level value corresponding to the scale 1 is 36.8dB, the sound pressure level value corresponding to the scale 2 is 47.9dB, and the like, each volume scale is divided by 8, and the scales are normalized within the range of [0,1], namely, the sound pressure level value corresponding to the scale 0.1 is 36.8dB, the sound pressure level value corresponding to the scale 0.2 is 47.9dB, and the like. An example of the volume adjustment scatter after scale normalization is further shown in fig. 5.
In this embodiment, whether according to the volume adjustment curve before scale normalization or according to the volume adjustment scatter diagram after scale normalization, the volume adjustment curve is found to be a nonlinear function under the condition of uniform loudness change determined based on auditory perception, and then curve fitting is performed according to the volume adjustment scatter diagram, so as to obtain a sound pressure level fitting curve. And calculating the sound pressure level value corresponding to the current scale to be configured based on the curve trend of the sound pressure level fitting curve and the proportional relation between the current scale to be configured and the total number of scales. The pre-fit thus forms a curve that is easier to calculate to determine the sound pressure level value for each scale than for discrete sample points.
For example, the proportional relation between the current scale to be configured and the total number of scales can be substituted into the sound pressure level fitting curve, and the ordinate of the sound pressure level fitting curve is determined to be the sound pressure level value corresponding to the current scale to be configured.
Alternatively, the sound pressure level fitting curve is represented by the following volume configuration log equation:
y＝aln(x/k)+b；
wherein k represents the total number of scales, and the value range is an integer in [1, + ]; x represents the current scale to be configured, and the value range is an integer in [0, k ] or [1, k ]; y represents the sound pressure level of the scale to be configured currently; a and b represent constants.
In this embodiment, no matter according to the volume adjustment curve before scale normalization or the volume adjustment scatter diagram after scale normalization, the trend of the volume adjustment curve can be found to be more consistent with a logarithmic equation under the condition of uniform loudness change determined based on auditory perception, so that the logarithmic equation can be used to represent a sound pressure level fitting curve, and a logarithmic equation is configured by taking the total number of scales and the currently to-be-configured scale as independent variables and the sound pressure level value corresponding to the currently to-be-configured scale as the dependent variable. Where constant a represents the slope and constant b represents the intercept. According to the difference of the sound pressure level sample sets, constants a and b in the volume configuration logarithmic equation obtained by fitting are also different. By the identification of the logarithmic equation, the amount of calculation for determining the sound pressure level can be reduced.
For example, after the total number of scales of the device to be configured and the current scale to be configured are obtained, the total number of scales and the current scale to be configured can be directly substituted into a volume configuration logarithmic equation, and the sound pressure level value corresponding to the current scale to be configured is obtained through calculation and solution.
S430, according to the determined sound pressure level value, carrying out volume configuration on the equipment to be configured.
According to the technical scheme, through the sound pressure level sample set capable of representing the corresponding relation between the volume scale of the equipment and the auditory perception sound pressure level, a sound pressure level curve is pre-fitted based on the sound pressure level sample set, and volume calculation and configuration are carried out on the equipment to be configured according to the sound pressure level curve. The collection cost of the sound pressure level sample set is low, and based on big data sample processing, the sound pressure level curve is easier to calculate and determine the sound pressure level value of each scale, so that the influence of manual intervention and manual subjective experience in volume configuration is avoided, the technical problems of unscientific volume configuration and uneven price of scale adjustment loudness change are overcome, the hearing experience brought by the actual volume adjustment of a user is improved, the technical effects of scientificity, accuracy and efficiency of volume configuration in equipment are improved, and the volume configuration cost of the equipment is reduced

S630, according to the determined sound pressure level value, volume configuration is carried out on the equipment to be configured.
S640, determining the total number of scales after the user adjusts in response to the adjustment operation of the user on the total number of scales.

For example, assuming that the device has the total number of scales in a factory configuration, it is necessary to appropriately increase the degree of variation between the scales of the device for a hearing insensitive user such as the elderly, and thus the total number of scales of the device can be reduced. For another example, for users of audio production, an accurate volume adjustment is required, so the total number of scales of the device can be increased, so that the degree of change of volume between scales is reduced, and a way for fine tuning the volume is provided for users.
