Room Transfer Function Estimation and Room Equalization in Noise Environments

Audio quality in listening situation is degraded by indoor room reverberation. Room equalization can be used to
increase the audio quality by applying the inverse transfer function to the input audio signals. In noise
environments, however, it is hard to exactly measure the room transfer function. In this work, we developed the
techniques to measure the room transfer function in indoor noise environments and to enhance the audio quality
by room equalization. From the experimental results, we showed that the proposed techniques can be
successfully used in indoor noise environments.
