Abstract
The present invention features systems for dynamically adjusting audio signals by applying a gain to the signal in a spectrally varying manner to compensate for ambient noise, such that the sound is perceived to be unchanged in volume and spectral composition by the listener. The system obtains a threshold elevation for each frequency component by analyzing the spectral composition of the ambient noise. This threshold elevation is then used by a psychoacoustic model of hearing to determine an appropriate gain adjustment for the corresponding frequency component of the source signal which will make that source signal perceived by the human ear to be just as loud as if the noise were not present.
