Sound masking in buildings
Sound masking is the process of adding a low level, unobtrusive background sound to an environment to reduce the intelligibility of human speech and reduce noise distractions in that environment. The sound is typically introduced through speakers installed in or above the ceiling.
It is the process of adding to an environment a low level of unobtrusive background sound engineered to protect confidentiality and reduce distractions by reducing the intelligibility of speech, thus making the acoustical environment more comfortable. A well executed sound masking system will improve confidentiality, improve concentration and lead to increased productivity as less time is lost overhearing casual conversation or intrusive noises.
