摘要： A method and system for attenuating noise comprises identifying a location in an area at which sound emitted from one or more speakers has acoustic characteristics that are substantially similar in measure to corresponding acoustic characteristics of the emitted sound at a location approximated to be near an ear of an occupant of the area. A microphone, which may be a virtual microphone, is disposed at the identified location. The microphone detects sound at the identified location. In response to the sound detected by the microphone, the one or more speakers emit a noise-canceling audio signal adapted to attenuate one or more frequencies in the sound detected by the microphone.

摘要： The invention discloses a headset communication method under a strong-noise environment and a headset. The method comprises: using earplugs to reduce medium and high frequency noises entering an ear canal, using an external connection cavity in parallel connection with the ear canal to divert medium and low frequency noises; using an internal microphone to pick up the sound in the ear canal and an environmental noise signal entering the ear canal, using an external microphone to pick up the environmental noise signal, and taking the external microphone signal as reference signals to eliminate the noise element in the internal microphone signal and remain the voice element to obtain transmitting terminal signals of the headset; using sound dynamic compression technology to cut down and compensate the signals picked up by the external microphone in terms of sound pressure level such that the sound pressure range is compressed to a range acceptable by human ears and the signals picked up by the external microphone and the receiving terminal signal received by the headset are broadcast together through a receiver of the headset. By means of the technical scheme of the present invention, the functions of protecting hearing, enhancing voice and monitoring a three-dimensional environment can be achieved comprehensively under strong-noise environments.
