具体实施方式detailed description
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
本发明提供一种电视机声音调整方法。The invention provides a TV sound adjustment method.
参照图1，图1为本发明电视机声音调整方法第一实施例的流程示意图。Referring to FIG. 1 , FIG. 1 is a schematic flowchart of a first embodiment of a method for adjusting the sound of a television set according to the present invention.
在第一实施例中，该电视机声音调整方法包括：In the first embodiment, the TV sound adjustment method includes:
步骤S10，采集电视机所在外界环境中的混合声音和电视机发出的原始声音；Step S10, collecting the mixed sound in the external environment where the TV is located and the original sound from the TV;
电视机中设有麦克风，该麦克风用于采集电视机所在外界环境中的混合声音，和电视机发出的原始声音；其中混合声音包括环境本身产生的声音(例如人的谈话声音、手机铃声等)以及电视机发出的原始声音经环境中人或物(例如墙壁、家居等)反射回来的反射声音，并且电视机采集其发出的原始声音作为采样声音。There is a microphone in the TV, which is used to collect the mixed sound in the external environment where the TV is located, and the original sound from the TV; the mixed sound includes the sound produced by the environment itself (such as the voice of people talking, the ringtone of mobile phones, etc.) And the original sound emitted by the TV is reflected by people or objects in the environment (such as walls, households, etc.), and the original sound emitted by the TV is collected as a sampled sound.
步骤S20，根据原始声音，将混合声音分离为电视机发出的经外界环境反射回来的反射声音和外界环境中存在的环境声音；Step S20, according to the original sound, separate the mixed sound into the reflected sound emitted by the TV and reflected by the external environment and the ambient sound existing in the external environment;
电视机将采集到的原始声音作为采样声音，根据该采样声音将混合声音分为反射声音和环境声音，具体地，电视机将混合声音波形减去适当减小的采样声音波形，从而得到环境声音波形，从而得到环境声音；然后将混合声音波形减去得到的环境声音波形，从而得到反射声音波形，从而得到反射声音，最后将反射声音和环境声音分别标识存储。The TV takes the collected original sound as the sampled sound, and divides the mixed sound into reflected sound and ambient sound according to the sampled sound. Specifically, the TV subtracts the appropriately reduced sampled sound waveform from the mixed sound waveform to obtain the ambient sound waveform to obtain the ambient sound; then subtract the obtained ambient sound waveform from the mixed sound waveform to obtain the reflected sound waveform, thereby obtaining the reflected sound, and finally mark and store the reflected sound and the ambient sound respectively.
步骤S30，根据反射声音和环境声音的音量，调整电视机发出的混响声音和/或低频声音的音量。Step S30, adjusting the volume of the reverberation sound and/or the low-frequency sound emitted by the TV according to the volume of the reflected sound and the ambient sound.
电视机根据综合反射声音和环境声音的音量，动态地调整电视机发出的混响声音(声波在室内传播时，要被墙壁、天花板、地板等障碍物反射，每反射一次都要被障碍物吸收一些。这样，当声源停止发声后，声波在室内要经过多次反射和吸收，最后才消失，我们就感觉到声源停止发声后声音还继续一段时间，这种现象叫做混响。混响声音为电视机模拟真实环境下的混响声效果)的音量，若电视机无播放混响声音的功能可以调整低频声音的音量来提高电视机发出声音的效果(即提高电视机发出声音的人的语言信息的清晰度)，若调整电视机发出的混响声音的音量对声音效果调整作用很弱，可以同时调整电视机发出的混响声音和低频声音的音量；其中，低频声音为频率在20Hz～150Hz范围内的声音，低频声音多为背景音乐或提高音色和饱满度的辅助声音，高于低频声音频率的声音为中频声音，中频声音频率范围为150Hz～5000Hz，绝大部分人的声音属于中频声音的频率范围。The TV dynamically adjusts the reverberation sound emitted by the TV according to the volume of the comprehensive reflected sound and the ambient sound (when sound waves propagate indoors, they are reflected by obstacles such as walls, ceilings, floors, etc., and each reflection must be absorbed by obstacles Some. In this way, when the sound source stops sounding, the sound wave will go through multiple reflections and absorptions in the room before disappearing, and we will feel that the sound continues for a period of time after the sound source stops sounding. This phenomenon is called reverberation. Reverberation The sound is the volume of the TV simulating the reverberation sound effect in the real environment). If the TV does not have the function of playing reverberation sound, you can adjust the volume of the low-frequency sound to improve the sound effect of the TV (that is, to increase the sound effect of the person who makes the TV sound). Clarity of language information), if adjusting the volume of the reverberation sound from the TV has little effect on the adjustment of the sound effect, you can adjust the volume of the reverberation sound and the low-frequency sound from the TV at the same time; among them, the low-frequency sound is at a frequency of 20Hz For sounds in the range of ~150Hz, low-frequency sounds are mostly background music or auxiliary sounds to improve timbre and fullness, and sounds higher than low-frequency sounds are intermediate-frequency sounds. The frequency range of mid-frequency sounds.
优选地，参照图2，步骤S30包括：Preferably, referring to FIG. 2, step S30 includes:
步骤S301，判断反射声音的音量是否大于预设的反射音量阈值，Step S301, judging whether the volume of the reflected sound is greater than a preset reflection volume threshold,
若是，则减小电视机发出的混响声音和/或低频声音的音量；If yes, reduce the volume of reverberant and/or low-frequency sounds from the TV;
若否，则增大电视机发出的混响声音和/或低频声音的音量；If not, increase the volume of reverberant sounds and/or low frequency sounds from the TV;
当电视机判断反射声音的音量大于预设的反射音量阈值时(即环境的消音效果不好，反射声音过大，可能导致用户无法听清楚电视机中播放的对话内容)，则减小了电视机发出的混响声音，以减小反射声音的音量，使用户可以听清楚电视机所播放的对话声音；若电视机没有播放混响声音的功能，则减小低频声音的音量(即减小了背景音乐声音的音量)，使电视机播放的人的说话声音更清楚；也可以同时减小电视机发出的混响声音和低频声音音量，以减小反射声音的音量，同时减小电视机发出声音中背景音乐声音的音量，突显电视机播放的中频声音(即人的说话声音)，从而达到提高电视机声音效果的目的。When the TV judges that the volume of the reflected sound is greater than the preset reflected volume threshold (that is, the environment's noise reduction effect is not good, and the reflected sound is too loud, which may cause the user to be unable to hear clearly the dialogue content played on the TV), then reduce the volume of the TV. The reverberation sound from the TV set can be used to reduce the volume of the reflected sound so that the user can clearly hear the dialogue sound played by the TV; if the TV does not have the function of playing reverberation sound, reduce the volume of the low-frequency sound the volume of the background music sound), so that the voice of the person playing on the TV is clearer; it can also reduce the volume of the reverberation sound and low-frequency sound emitted by the TV at the same time, so as to reduce the volume of the reflected sound, and at the same time reduce the volume of the TV The volume of the background music in the sound output highlights the intermediate frequency sound (that is, the human voice) played by the TV, so as to achieve the purpose of improving the sound effect of the TV.
当电视机判断反射声音的音量小于预设的反射音量阈值(即环境的吸音过多，电视机发出的混响声音过少，低频声音过少，声音听起来不好听不饱满)，则增大电视机发出的混响声音，提高混响效果；若电视机没有播放混响声音的功能，则增大低频声音的音量(即增大背景音乐声音的音量)，提高了电视机的声音效果；也可以同时增大电视机发出的混响声音和低频声音音量，以提高电视机播放声音的饱和度，使电视机播放声音更好听，从而达到提高电视机声音效果的目的。When the TV judges that the volume of the reflected sound is lower than the preset reflected volume threshold (that is, the environment has too much sound absorption, the reverberation sound from the TV is too little, the low-frequency sound is too little, and the sound does not sound good or full), then increase the The reverberation sound that the TV sends improves the reverberation effect; if the TV does not have the function of playing the reverberation sound, then increase the volume of the low-frequency sound (that is, increase the volume of the background music sound), and improve the sound effect of the TV; You can also increase the reverberation sound and low-frequency sound volume from the TV at the same time to increase the saturation of the sound played by the TV and make the sound played by the TV better, so as to achieve the purpose of improving the sound effect of the TV.
步骤S302，判断环境声音的音量是否大于预设的环境音量阈值，Step S302, judging whether the volume of the ambient sound is greater than a preset ambient volume threshold,
若是，则增大电视机发出的混响声音音量和/或减小低频声音的音量；If so, increase the volume of reverberant sounds from the TV and/or reduce the volume of low-frequency sounds;
若否，则不作处理。If not, do not process.
当电视机判断环境声音的音量大于预设的环境音量阈值(即电视机所处环境的环境声音过大)，则需要增大电视机发出的混响声音音量，让用户在较吵的环境下能够听清楚电视机发出的声音；当电视机没有播放混响声音的功能或调整混响声音音量作用不大时，可以减小低频声音的音量，突显中频声音(即电视机播出的人对对话声音)，以调整电视机的声音效果。When the TV judges that the volume of the ambient sound is greater than the preset ambient volume threshold (that is, the ambient sound of the environment where the TV is located is too loud), it is necessary to increase the volume of the reverberation sound emitted by the TV so that the user can enjoy the sound in a noisy environment. Can hear the sound from the TV clearly; when the TV does not have the function of playing reverberation sound or adjusting the volume of the reverberation sound has little effect, you can reduce the volume of the low-frequency sound and highlight the middle-frequency sound dialogue sound) to adjust the sound effect of the TV.
在本实施例中，通过采集电视机所在外界环境中的混合声音和电视机发出的原始声音，并根据原始声音，将采集的混合声音分离为反射声音和环境声音，最后根据反射声音和环境声音调整电视机发出的混响声音和/或低频声音的音量，这样，电视机根据实时采集的反射声音和环境声音对电视机发出的混响声音和/或低频声音的音量进行动态的调节，以达到更好的声音效果，让用户可以听到清晰、准确的电视机声音。In this embodiment, by collecting the mixed sound in the external environment where the TV is located and the original sound emitted by the TV, and according to the original sound, the collected mixed sound is separated into reflected sound and ambient sound, and finally according to the reflected sound and ambient sound Adjust the volume of the reverberation sound and/or low-frequency sound emitted by the TV set, so that the TV set dynamically adjusts the volume of the reverberation sound and/or low-frequency sound emitted by the TV set according to the reflected sound and ambient sound collected in real time, so as to To achieve better sound effects, so that users can hear clear and accurate TV sound.
进一步地，参照图3，步骤S302之后还包括：Further, referring to FIG. 3, after step S302, it also includes:
步骤S40，根据反射声音的音量与反射音量阈值的差值，得出对应的用于确定调整电视机发出的混响声音和/或低频声音的音量大小的第一参考值，并为第一参考值分配对应的第一权值；Step S40, according to the difference between the volume of the reflected sound and the threshold of the reflected volume, the corresponding first reference value for determining and adjusting the volume of the reverberation sound and/or low-frequency sound emitted by the TV is obtained, and is the first reference value The first weight corresponding to the value distribution;
步骤S50，根据环境声音的音量与环境音量阈值的差值，得出对应的用于确定调整电视机发出的混响声音和/或低频声音的音量大小的第二参考值，并为第二参考值分配对应的第二权值；Step S50, according to the difference between the volume of the ambient sound and the threshold of the ambient volume, the corresponding second reference value for determining and adjusting the volume of the reverberation sound and/or low-frequency sound emitted by the TV is obtained, and is the second reference value. The second weight corresponding to the value distribution;
步骤S60，将第一参考值与第一权值的乘积加上第二参考值与第二权值的乘积得到最终参考值，并根据最终参考值调整电视机发出的混响声音和/或低频声音的音量大小。Step S60, adding the product of the first reference value and the first weight to the product of the second reference value and the second weight to obtain the final reference value, and adjusting the reverberation sound and/or low frequency emitted by the TV according to the final reference value The volume of the sound.
优选地，反射声音的音量与反射音量阈值的差值的相反数为第一参考值，环境声音的音量与环境音量阈值的差值大于等于0时，该差值与第二参考值相等；环境声音的音量与环境音量阈值的差值小于0时，该差值为0。Preferably, the opposite number of the difference between the volume of the reflected sound and the reflected volume threshold is the first reference value, and when the difference between the volume of the ambient sound and the ambient volume threshold is greater than or equal to 0, the difference is equal to the second reference value; When the difference between the sound volume and the ambient volume threshold is less than 0, the difference is 0.
优选地，第一权值和第二权值为0至1之间的任意数，且第一权值与第二权值相加之和为1。Preferably, the first weight and the second weight are any numbers between 0 and 1, and the sum of the first weight and the second weight is 1.
在本实施例中，电视机根据反射声音的音量与反射音量阈值的差值(即第一参考值)对电视机发出的混响声音和/或低频声音的音量大小进行调整；同时根据环境声音的音量与环境音量阈值的差值(即第二参考值)对电视机发出的混响声音和/或低频声音的音量大小进行调整，但是反射声音和环境声音对电视机声音效果的影响不同，所以对第一参考值和第二参考值赋予不同的权值；具体实施例：若反射声音的音量是40单位，反射音量阈值是30单位，分配的第一权值为0.9，且环境声音的音量为30，环境音量阈值时20，第二权值为0.1，则第一参考值为-10，第二参考值为10，最终参考值等于-8，即减小8单位电视机发出的混响声音和/或低频声音的音量。In this embodiment, the TV adjusts the volume of the reverberation sound and/or low-frequency sound emitted by the TV according to the difference between the volume of the reflected sound and the threshold of the reflected volume (that is, the first reference value); The difference between the volume of the volume and the ambient volume threshold (i.e. the second reference value) adjusts the volume of the reverberation sound and/or low-frequency sound emitted by the TV, but the reflected sound and the ambient sound have different influences on the sound effect of the TV. Therefore, different weights are given to the first reference value and the second reference value; specific embodiment: if the volume of the reflected sound is 40 units, the reflection volume threshold is 30 units, the assigned first weight is 0.9, and the volume of the ambient sound The volume is 30, the ambient volume threshold is 20, and the second weight is 0.1, then the first reference value is -10, the second reference value is 10, and the final reference value is equal to -8, that is, the mixing sound emitted by the TV is reduced by 8 units. volume of loud and/or low-frequency sounds.

电视机中设有麦克风，该麦克风用于采集电视机所在外界环境中的混合声音，和电视机发出的原始声音；其中混合声音包括环境本身产生的声音(例如人的谈话声音、手机铃声等)以及电视机发出的原始声音经环境中人或物(例如墙壁、家居等)反射回来的反射声音，并且电视机采集其发出的原始声音作为采样声音。There is a microphone in the TV, which is used to collect the mixed sound in the external environment where the TV is located, and the original sound from the TV; the mixed sound includes the sound produced by the environment itself (such as the voice of people talking, the ringtone of mobile phones, etc.) And the original sound emitted by the TV is reflected by people or objects in the environment (such as walls, households, etc.), and the original sound emitted by the TV is collected as a sampled sound.
声音分离模块80，用于根据原始声音，将混合声音分离为电视机发出的经外界环境反射回来的反射声音和外界环境中存在的环境声音；The sound separation module 80 is used to separate the mixed sound into the reflected sound emitted by the TV and reflected by the external environment and the ambient sound existing in the external environment according to the original sound;
电视机将采集到的原始声音作为采样声音，根据该采样声音将混合声音分为反射声音和环境声音，，具体地，电视机将混合声音波形减去适当减小的采样声音波形，从而得到环境声音波形，从而得到环境声音；然后将混合声音波形减去得到的环境声音波形，从而得到反射声音波形，从而得到反射声音，最后将反射声音和环境声音分别标识存储。The TV takes the collected original sound as the sampled sound, and divides the mixed sound into reflected sound and ambient sound according to the sampled sound. Specifically, the TV subtracts the appropriately reduced sampled sound waveform from the mixed sound waveform to obtain the ambient sound The sound waveform is obtained to obtain the ambient sound; then the mixed sound waveform is subtracted from the obtained environmental sound waveform to obtain the reflected sound waveform, thereby obtaining the reflected sound, and finally the reflected sound and the ambient sound are respectively marked and stored.
声音调整模块90，用于根据反射声音和环境声音的音量，调整电视机发出的混响声音和/或低频声音的音量。The sound adjustment module 90 is configured to adjust the volume of the reverberation sound and/or the low-frequency sound emitted by the TV according to the volume of the reflected sound and the ambient sound.
电视机根据综合反射声音和环境声音的音量，动态地调整电视机发出的混响声音(声波在室内传播时，要被墙壁、天花板、地板等障碍物反射，每反射一次都要被障碍物吸收一些。这样，当声源停止发声后，声波在室内要经过多次反射和吸收，最后才消失，我们就感觉到声源停止发声后声音还继续一段时间，这种现象叫做混响。混响声音为电视机模拟真实环境下的混响声效果)的音量，若电视机无播放混响声音的功能可以调整低频声音的音量来提高电视机发出声音的效果(即提高电视机发出声音的人的语言信息的清晰度)，若调整电视机发出的混响声音的音量对声音效果调整作用很弱，可以同时调整电视机发出的混响声音和低频声音的音量；其中，低频声音为频率在20Hz～150Hz范围内的声音，低频声音多为背景音乐或提高音色和饱满度的辅助声音，高于低频声音频率的声音为中频声音，中频声音频率范围为150Hz～5000Hz，绝大部分人的声音属于中频声音的频率范围。The TV dynamically adjusts the reverberation sound emitted by the TV according to the volume of the comprehensive reflected sound and the ambient sound (when sound waves propagate indoors, they are reflected by obstacles such as walls, ceilings, floors, etc., and each reflection must be absorbed by obstacles Some. In this way, when the sound source stops sounding, the sound wave will go through multiple reflections and absorptions in the room before disappearing, and we will feel that the sound continues for a period of time after the sound source stops sounding. This phenomenon is called reverberation. Reverberation The sound is the volume of the TV simulating the reverberation sound effect in the real environment). If the TV does not have the function of playing reverberation sound, you can adjust the volume of the low-frequency sound to improve the sound effect of the TV (that is, to increase the sound effect of the person who makes the TV sound). Clarity of language information), if adjusting the volume of the reverberation sound from the TV has little effect on the adjustment of the sound effect, you can adjust the volume of the reverberation sound and the low-frequency sound from the TV at the same time; among them, the low-frequency sound is at a frequency of 20Hz For sounds in the range of ~150Hz, low-frequency sounds are mostly background music or auxiliary sounds to improve timbre and fullness, and sounds higher than low-frequency sounds are intermediate-frequency sounds. The frequency range of mid-frequency sounds.

当电视机判断反射声音的音量大于预设的反射音量阈值时(即环境的消音效果不好，反射声音过大，可能导致用户无法听清楚电视机中播放的对话内容)，则减小了电视机发出的混响声音，以减小反射声音的音量，使用户可以听清楚电视机所播放的对话声音；若电视机没有播放混响声音的功能，则减小低频声音的音量(即减小了背景音乐声音的音量)，使电视机播放的人的说话声音更清楚；也可以同时减小电视机发出的混响声音和低频声音音量，以减小反射声音的音量，同时减小电视机发出声音中背景音乐声音的音量，突显电视机播放的中频声音(即人的说话声音)，从而达到提高电视机声音效果的目的。When the TV judges that the volume of the reflected sound is greater than the preset reflected volume threshold (that is, the environment's noise reduction effect is not good, and the reflected sound is too loud, which may cause the user to be unable to hear clearly the dialogue content played on the TV), then reduce the volume of the TV. The reverberation sound from the TV set can be used to reduce the volume of the reflected sound so that the user can clearly hear the dialogue sound played by the TV; if the TV does not have the function of playing reverberation sound, reduce the volume of the low-frequency sound the volume of the background music sound), so that the voice of the person playing on the TV is clearer; it can also reduce the volume of the reverberation sound and low-frequency sound emitted by the TV at the same time, so as to reduce the volume of the reflected sound, and at the same time reduce the volume of the TV The volume of the background music in the sound output highlights the intermediate frequency sound (that is, the human voice) played by the TV, so as to achieve the purpose of improving the sound effect of the TV.
当电视机判断反射声音的音量小于预设的反射音量阈值(即环境的吸音过多，电视机发出的混响声音过少，低频声音过少，声音听起来不好听不饱满)，则增大电视机发出的混响声音，提高混响效果；若电视机没有播放混响声音的功能，则增大低频声音的音量(即增大背景音乐声音的音量)，提高了电视机的声音效果；也可以同时增大电视机发出的混响声音和低频声音音量，以提高电视机播放声音的饱和度，使电视机播放声音更好听，从而达到提高电视机声音效果的目的。When the TV judges that the volume of the reflected sound is lower than the preset reflected volume threshold (that is, the environment has too much sound absorption, the reverberation sound from the TV is too little, the low-frequency sound is too little, and the sound does not sound good or full), then increase the The reverberation sound that the TV sends improves the reverberation effect; if the TV does not have the function of playing the reverberation sound, then increase the volume of the low-frequency sound (that is, increase the volume of the background music sound), and improve the sound effect of the TV; You can also increase the reverberation sound and low-frequency sound volume from the TV at the same time to increase the saturation of the sound played by the TV and make the sound played by the TV better, so as to achieve the purpose of improving the sound effect of the TV.
环境判断单元902，用于判断环境声音的音量是否大于预设的环境音量阈值，若是，则增大电视机发出的混响声音音量和/或减小低频声音的音量；若否，则不作处理。The environment judging unit 902 is used to judge whether the volume of the ambient sound is greater than the preset ambient volume threshold, if so, increase the volume of the reverberation sound sent by the TV set and/or reduce the volume of the low-frequency sound; if not, do not process .
当电视机判断环境声音的音量大于预设的环境音量阈值(即电视机所处环境的环境声音过大)，则需要增大电视机发出的混响声音音量，让用户在较吵的环境下能够听清楚电视机发出的声音；当电视机没有播放混响声音的功能或调整混响声音音量作用不大时，可以减小低频声音的音量，突显中频声音(即电视机播出的人对对话声音)，以调整电视机的声音效果。When the TV judges that the volume of the ambient sound is greater than the preset ambient volume threshold (that is, the ambient sound of the environment where the TV is located is too loud), it is necessary to increase the volume of the reverberation sound emitted by the TV so that the user can enjoy the sound in a noisy environment. Can hear the sound from the TV clearly; when the TV does not have the function of playing reverberation sound or adjusting the volume of the reverberation sound has little effect, you can reduce the volume of the low-frequency sound and highlight the middle-frequency sound dialogue sound) to adjust the sound effect of the TV.
在本实施例中，通过采集电视机所在外界环境中的混合声音和电视机发出的原始声音，并根据原始声音，将采集的混合声音分离为反射声音和环境声音，最后根据反射声音和环境声音调整电视机发出的混响声音和/或低频声音的音量，这样，电视机根据实时采集的反射声音和环境声音对电视机发出的混响声音和/或低频声音的音量进行动态的调节，以达到更好的声音效果，让用户可以听到清晰、准确的电视机声音。In this embodiment, by collecting the mixed sound in the external environment where the TV is located and the original sound emitted by the TV, and according to the original sound, the collected mixed sound is separated into reflected sound and ambient sound, and finally according to the reflected sound and ambient sound Adjust the volume of the reverberation sound and/or low-frequency sound emitted by the TV set, so that the TV set dynamically adjusts the volume of the reverberation sound and/or low-frequency sound emitted by the TV set according to the reflected sound and ambient sound collected in real time, so as to To achieve better sound effects, so that users can hear clear and accurate TV sound.
进一步地，参照图6，声音调整模块90还包括：Further, referring to Fig. 6, the sound adjustment module 90 also includes:
第一分配单元903，用于根据反射声音的音量与反射音量阈值的差值，得出对应的用于确定调整电视机发出的混响声音和/或低频声音的音量大小的第一参考值，并为第一参考值分配对应的第一权值；The first allocating unit 903 is configured to obtain a corresponding first reference value for determining and adjusting the volume of the reverberation sound and/or low-frequency sound emitted by the TV according to the difference between the volume of the reflected sound and the threshold of the reflected volume, and assigning a corresponding first weight to the first reference value;
第二分配单元904，用于根据环境声音的音量与环境音量阈值的差值，得出对应的用于确定调整电视机发出的混响声音和/或低频声音的音量大小的第二参考值，并为第二参考值分配对应的第二权值；The second allocation unit 904 is configured to obtain a corresponding second reference value for determining and adjusting the volume of the reverberation sound and/or low-frequency sound emitted by the TV according to the difference between the volume of the ambient sound and the threshold of the ambient sound, and assigning a corresponding second weight to the second reference value;
最终调整单元905，用于将第一参考值与第一权值的乘积加上第二参考值与第二权值的乘积得到最终参考值，并根据最终参考值调整电视机发出的混响声音和/或低频声音的音量大小。The final adjustment unit 905 is configured to add the product of the first reference value and the first weight to the product of the second reference value and the second weight to obtain the final reference value, and adjust the reverberation sound emitted by the TV according to the final reference value and/or the volume level of low frequency sounds.
优选地，反射声音的音量与反射音量阈值的差值的相反数为第一参考值，环境声音的音量与环境音量阈值的差值大于等于0时，该差值与第二参考值相等；环境声音的音量与环境音量阈值的差值小于0时，该差值为0。Preferably, the opposite number of the difference between the volume of the reflected sound and the reflected volume threshold is the first reference value, and when the difference between the volume of the ambient sound and the ambient volume threshold is greater than or equal to 0, the difference is equal to the second reference value; When the difference between the sound volume and the ambient volume threshold is less than 0, the difference is 0.
