Sound Masking

What is sound masking?

Sound masking is the addition of sound or white noise,  created by special digital generators and distributed by normally unseen speakers through an area to reduce distractions or provide confidentiality where needed. The sound is broad band random that conveys no information about itself to a listener.

Sound masking is the “cover” portion of the equation. Sound masking is the addition of an unobtrusive background sound, similar to airflow, to reduce the intelligibility of human speech and reduce distractions. The resulting environment leads to greater productivity and increased privacy and comfort.

A white noise or sound masking system for offices is a great way to improve productivity while providing a more comfortable and efficient working envirionment. Office sound masking systems offer cost effective solutions to a noisy work place while at the same time can provide privacy when needed.  The speech privacy systems have been developed and used in hospitals call centers and many other locations where privacy is necessary.




What is the privacy index and how does adding sound increase privacy and reduce distractions?

Speech Privacy is the inability of an unintentional listener to understand someone’s words. The higher the privacy index, the more confidential the speaker’s conversation becomes. When someone’s conversation is clearly understood, the speech becomes a distraction and the speaker has less privacy. With the addition of Qt® sound masking, the speaker’s voice becomes less intelligible. Their voice becomes less of a distraction and their privacy increases.

Imagine looking up at the stars on a clear night:

The stars shine brightly against the night sky. As dawn breaks, the stars appear to dim as the ambient light increases. The intensity of the starlight has not changed, but rather as the ambient light increases, it becomes more difficult to discern the light from the stars.

This works the same for human speech. As the ambient sound in the room increases, it become more challenging to discern an individual’s conversation from across the room. This inability to understand the conversation reduces distractions and increases the speaker’s speech privacy.
