Sound masking is a technique used to improve acoustic privacy and reduce distractions in indoor environments. It involves the addition of a soft, unobtrusive background sound, often referred to as “white noise,” to mask or cover up unwanted noises and conversations. The purpose of sound masking is not to eliminate noise but to create a more comfortable and balanced acoustic environment. It is particularly beneficial in open office spaces, healthcare facilities, and other shared work environments where privacy and concentration are essential. By raising the ambient noise level, sound masking reduces speech intelligibility and helps prevent the leakage of sensitive information. It fosters a more productive and less stressful atmosphere by creating a sense of privacy and reducing the impact of disruptive sounds, resulting in increased focus, productivity, and overall well-being for occupants.
