Method for indoor communication

摘要

The method involves receiving system identification with an impulse response of a system, and evaluating the impulse response. System delay, reverberation time and frequency response are determined. Adjustment of amplification of a signal amplification device is taken place corresponding to evaluation of an impulse response of a system. The amplification of the signal amplification device in two different frequency bands are differently adjusted to the determined frequency response and psychoacoustically adapted to the system delay and/or reverberation time by an equalizing filter. Independent claims are also included for the following: (1) a software product comprising instructions to perform a method for improving communication in interior of a vehicle (2) an indoor communication system comprising a microphone.
