Evaluation of sound environments is a multifactorial task, comprizing measurement of both physical (acoustic) and auditory (psychoacoustic) quantities. Physical quantities are measured by physical methods, such offering the advantage that objective results can in general be achieved with less effort than in the case of auditory mesurement, where listening tests are mandatory. Aurally-Adequate Sound-Measuring Technology (AASMT) aims at estimating auditory quantities from the results of physical mesurements. In this context, Binaural Technology in the form of artivicial heads and binaural signal-processing is extensively applied. It is expected that more and more mesurement and analysis tasks in sound-environment evaluation which could hitherto only be performed via listening test, will adequatly be dealt with AASMT-in many cases even more effectively. Nevertheless, listening test will not become obsolete. Sound-environment evaluation will continue to rely on them, especially, when cognitive factors come into play. In the light of the complex parallelity of physical and psychoacoustical factors in sound-environment evaluation and the ever growing demands of society with regard to the quality of the environment, the authors ask the question of whether a new type of expert may evolve - the sound/noise manager - or whether teams of experts with different backgrounds (noise engineer, sound designers) will have to be formed to comply with future demands.
