Masking Sound SystemsMost commonly used and necessary in the open plan office layout, sound masking systems involve the generation of the generation of random noise fed through speakers uniformly distributed though out the office to produce a subtle and uniform masking sound level. Sound masking systems provide the means to maintain speech confidentiality as well as a masking protection against other intrusive and distracting noises in the office environment. |
