ASA-2000 Audio Spectrum Analysis Software

 REI announces the availability of Audio Spectrum Analysis Software for use with the ANG-2200 (Acoustic Noise Generator). The software gives the user the ability to analyze the effectiveness of acoustic masking in a specific environment. Using audio noise to mask sensitive or confidential conversations is a useful technique that has been utilized for many years, however it is a basic technology that is often misunderstood and improperly implemented.

REI's Audio Spectrum Analysis Software provides the capability to measure the audio that is absorbed by environmental structures, and then analyze and adjust noise-masking levels for an effective countermeasure.

Whether you are considering implementing acoustic masking noise (white noise or pink noise) as a countermeasure, or you have already implemented a noise masking system, see REI's website and the Acoustic Noise Masking Primer for more information on the effects of voice band noise masking and guidance on proper audio noise masking system installation. This software will be available in October, 2003 and will be sold with an Acoustics Leakage Laptop Probe (ALL-200).
