Achieve acoustical privacy in open and partitioned office areas by installing Atlas Sound’s self contained, audio masking system — The Masker. Compact assembly adds low-level sound into environment to obscure ambient noise, achieving conversational privacy in designated areas. Easy-to-install system may be used in general application to increase privacy and/or productivity in individual cubical and work areas by “blocking out” surrounding conversation. It is also used in individual office areas, common waiting areas, and professional offices where confidential conversations occur. The equalized masking sound lowers intelligibility and “masks” disruptive outside sounds. Order external power supply separately, part number PS16-40AC.
