What is Sound Masking?

Sound masking is an airflow-type background sound added to an environment. This sound is designed to cover-up unwanted conversations because it contains the same frequencies as human speech. The sound masking easily blends into the environment and makes other conversations more difficult – or impossible – to understand, and therefore more private and less distracting.

Sound Masking is designed to cover:

  • Human Voice (normal speech volume)
  • Light office sounds such as keyboard typing and papers shuffling
  • Some echoes in reverberant spaces
  • Light traffic noise

Sound masking is the only acoustical treatment that addresses all sound paths. The acoustical effect of walls, carpets and ceilings are static; sound masking can be tuned and adjusted as needed.

Adding sound masking to an open office space is the acoustical equivalent of tripling the distance between workers!

Qt Pro is a sound masking system engineered to provide exceptional sound masking in today’s changing workplace.

Qt Pro is a complete enterprise solution supporting multiple zones. A variety of control modules help fine-tune the appropriate solution for offices from thousands of square feet to hundreds of thousands of square feet.

In addition to sound masking, Qt Pro supports the distribution of music and paging. Network control provides the ability to adjust volume levels and control advanced features over the local area network.
