In general, the human ear responds to the amplitude range of sound. This amplitude is expressed in decibel sound pressure level (dBSPL, 0dBSPL = 0.0002 microbar). 0dBSPL is the threshold for the smallest sound that humans can hear in the air, and 120 dBSPL is the painful threshold. 1 dB is the minimum change in sound pressure level (SPL) that can be felt audibly. A 3dB change is usually a detectable range of change, while a 6dB change is a noticeable range of change. A 10 dB change is a range of change that makes the sound feel twice as loud.

Assume that it is mounted on the part that does not.

First, it is determined whether the cover (eg, a folder) of the wireless communication terminal is open (401).
