HEADSET COMMUNICATION METHOD UNDER A STRONG-NOISE ENVIRONMENT AND HEADSET

摘要

The present invention discloses a headset communication method and a headset under a strong noise environment. The method comprises: using an earplug to reduce intermediate frequency and high frequency noise entering the ear canal and using an external connecting cavity in parallel with the ear canal to branch out intermediate frequency and low frequency noises; An internal microphone is used to pick up the ambient noise signal and sound from the ear canal entering the ear canal, an external microphone is used to pick up the ambient noise signal, and a noise from the internal microphone signal Taking an external microphone signal as reference signals to remove components and leave a speech component; Using sound dynamics compression techniques to reduce and compensate for signals picked up by the external microphone in terms of sound pressure level so that the sound pressure range is compressed to the extent that it can be accepted by the human ear; The signals picked up by the external microphone and the received-end signals received by the headset are broadcast together through the receiver of the headset. By means of the technical solution of the present invention, the functions of protecting the hearing, improving the voice and monitoring the three-dimensional environment can be completely achieved under a strong noise environment.
