Noise - Environmental - Home Insulation - MaskingSolving Problems by Making More (Masking) Noise
There are some noises which are easy to ignore; they tend to be bland, broad-band sounds with a fairly constant level, e.g. fan heaters, air-conditioning or waterfalls all produce this type of noise. By contrast many intrusive "problem" noises change rapidly in level and have unusual tones or impulses and may contain information (speech or music). The principle of masking noise or "sound masking" is to generate a "bland" noise at such a level that it masks the "problem" noise, such as the neighbour's party, or the telephone conversation at the next desk.
The masking sound can be produced by
Masking sound has great potential to reduce the impact of noise in the workplace and the home; however most people find it difficult to accept the idea that increasing noise levels will reduce the noise problem.
