Choctaw Defense Services can assist with all your sound masking needs.
Sound masking works on the principle that when background noise is added to an environment, speech is less intelligible. In technical terms, the “Articulation Index” – a measurement of how intelligible speech is – can be lowered by changing the signal-to-noise ratio. A high signal-to-noise ratio means that speech is very intelligible – an amphitheater would have a very high Articulation Index, for example. Based on this principle, scientists and engineers realized that you don’t have to actually stop the sound waves from a speaker’s voice in order to obtain speech privacy; instead, you can add background noise to mask the speaker’s words and make them unintelligible.
