As you know too well, you're bombarded with more messages every day than your mind can possibly process. Your brain, however, is quite adept at filtering out what it considers to be unstructured noises and signals that do not communicate information, while constantly searching for structured, meaningful types such as speaking, music, or noises that indicate a threat. You’ve experienced this kind of thing before. When you turn on your computer, you hear the cooling fan begin to spin. However, your mind quickly filters out and ignores this unstructured sound, rendering it effectively “invisible.” The goal of any speech privacy system is to add enough sound to an area to cover up speech, yet still be quiet enough to be almost imperceptible. Good, well-tuned, quality sound masking systems will produce sound that your mind naturally tunes out. The more uniformly the sound masking system accomplishes this throughout the treated area, the more “invisible” the sound becomes. |
