Abstract
The performance of automotive sound systems is compromised by the effects of acoustic noise. Digital techniques are necessary to measure the noise in a car accurately and to predict the effects of masking. It will be shown that it is possible to predict and reverse the effects of noise induced masking. The following paper will describe a system that modifies music signals to compensate for these effects. The system is similarly effective on music and speech.
