Realize procedure below：
Processor plays back the sound to be played with loudspeaker playing module, and the week of audio amplifier is then gathered with microphone
Side sound, the peripheral sound collected are first handled by processor with echo cancellation algorithm, to filter in own voice
Interference.After echo cancellor, processor carries out discrete Fourier frequency-domain transform to peripheral sound, each in peripheral sound so as to obtain
Spectrum component intensity table in frequency, each of which spectrum component intensity characterize the sound energy included on that frequency
Amount.
Because the frequency of voice is concentrated mainly on 300hz to 800hz scope, more accurately to know in peripheral sound
The intensity of voice, obtain respectively on 300hz, 350hz, 400hz, 450hz, 500hz, 550hz, 600hz, 650hz, 700hz
Spectrum component intensity, then carries out the B1 that averages to each spectrum component intensity in the range of 300hz-800hz, and average B1 is
Characterize the intensity of the voice in peripheral sound.After the intensity for obtaining voice, first the intensity of voice is compared in advance, if average B1
No more than threshold value C1 is started, then the back drop that treating as the voice to filter out is filtered out；Otherwise the output of audio amplifier is calculated
The decibel average value of volume, then compare voice intensity divided by this decibel of average value obtained by value whether be less than predetermined threshold value
A1, if then illustrating that the output level of voice and audio amplifier broadcasting sound approaches, audio amplifier plays sound and easily disturbs voice to talk, now
Automatically should be decayed the output volume of audio amplifier, avoid people's audio amplifier volume in talk from covering voice.When people does not talk again, average
B1 is decayed to less than threshold value D1, and now the output volume of audio amplifier is arranged to the state before not decaying by processor again.
Audio amplifier also needs to consider the volume of hum during broadcast, if hum is excessive, should increase the output volume of audio amplifier.By
Be concentrated mainly on 0hz to 300hz scope in the frequency of hum, thus obtain respectively 50hz, 100hz, 150hz, 200hz,
Spectrum component intensity on 250hz, the B2 that averages then is carried out to each spectrum component intensity in the range of 0hz-300hz, should
