Abstract
Noise is undesired sound. The decision, however, of whether a sound is desired or undesired, is taken by the listener in the specific situation of sound exposure. A sound that is noise for one listener, may be a useful, information carrying signal for another listener and, moreover, each listener may change his mind at any time depending on the circumstances. Consequently, once a noise level is reduced so far that a physiological danger for the listeners' ear is no longer present, a further reduction of the level may not be the adequate measure to further decrease the negative impacts of the noise. Instead, a careful redesign of the complete acoustical environment at the listeners' position may be required. To this end, proper, ear‐adequate methods for noise measurement and noise quality evaluation are needed. In this talk, some developments along these lines, as currently being discussed in Germany, will be reviewed and evaluated.
