A volume control system is designed to adjust the playback volume based on continuous measurements of the noise. The preferred listening levels under noisy conditions were determined in a user study. Comparison of the loudnesses of the noise and the target signal has shown to be a useful criterion for determining the optimal amplification. When music is concerned, timbral correction based on the equal loudness curves is applied in order to minimize coloration. The speech signals of a telephone call can be manipulated to a larger extent since the aesthetics are secondary. We show methods that maximize intelligibility under given limitations of the playback system.<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The preferred listening level for music and speech in cars depends on the environmental noise, which can vary dynamically.
