Improving sound quality measures through the multifaceted soundscape approach

摘要

Soundscape research represents a paradigm shift in the field of sound evaluation. First, it improves human perception, and, second, it expands on classical physical measurements and makes reference to the use of different investigative measurement methods. This multifaceted approach is basic to improving the validity of the research outcome on any subject or phenomenon, and it avoids systematic errors that can occur when relying on only one approach. The soundscape approach considers the conditions and purposes of a sound's production and how it is perceived. Consequently, it is necessary to understand that the evaluation of sound is a holistic process. The International Standard ISO/DIS 12913-1 has as its purpose the enabling of a broad international consensus on the definition of 'soundscape' and its respective evaluation. It is more than urgent to understand that there is the need to provide a solid foundation for communication across disciplines and professions with an interest in achievements on better solutions for the people concerned.
