when the decibel value of the environmental noise is determined to be larger than or equal to a first preset value and smaller than or equal to a second preset value, determining that the target decibel range is a first range;
when the decibel value of the environmental noise is determined to be larger than a second preset value, determining the target decibel range as a second range;
the second range is greater than the first range.
5. The building intercom audio automatic adjusting method according to claim 1, further comprising:
after the power is on, a pre-stored test audio is called, the test audio is processed by a preset algorithm to obtain and store the first audio processing efficiency value.
6. The building intercom audio automatic adjusting method according to claim 1, further comprising:
when the multiparty talkback is carried out, the input audio is transmitted to an audio processing end server;
and receiving and outputting the audio mixing audio transmitted by the audio processing end server, wherein the audio mixing audio is generated by processing the audio of the multi-party intercom device by the audio processing end server according to a preset algorithm and then mixing.
7. A building intercom audio frequency automatic regulating apparatus, its characterized in that includes:
the processing efficiency transmission module is used for transmitting the stored first audio processing efficiency value to the external talkback equipment and receiving a second audio processing efficiency value transmitted by the external talkback equipment after the unilateral talkback and the external talkback equipment are connected;
the processing efficiency comparison module is used for determining that the local equipment is an audio processing end when the first audio processing efficiency value is determined to be greater than the second audio processing efficiency value;
the audio processing module is used for processing the input audio of the microphone according to a preset algorithm and transmitting the processed audio to the external intercom device when the external intercom device talkbacks, and processing the remote audio transmitted by the external intercom device according to the preset algorithm and outputting the processed remote audio; wherein the preset algorithm processing comprises:
detecting the environmental noise of an audio output party, and determining a target decibel range according to the decibel value of the environmental noise;
detecting talkback voice in audio, and when the decibel value of the talkback voice is determined to be larger than the target decibel range, attenuating the talkback voice to the target decibel range;
and when the decibel value of the talkback voice is determined to be smaller than the target decibel range, performing gain processing on the talkback voice until the talkback voice is within the target decibel range.
8. A building intercom device comprising a memory and a processor, said memory storing a computer program which, when run on said processor, performs the building intercom audio automatic adjustment method as claimed in any one of claims 1 to 5.
9. A readable storage medium, characterized in that it stores a computer program which, when run on a processor, performs the building talk audio automatic adjustment method of any one of claims 1 to 5.
