Sounds good.

In order to control sound within any space there are three simple principles—known as the ABCs, to understand and apply. In particular, sound masking represents the C (Cover) which is imperative when the first two principles fail to achieve their full objectives:

  • Absorb—absorbing sound is typically achieved by introducing materials such as fabric wall or acoustical ceiling panels which have a high Noise Reduction Coefficient (NRC) value
  • Block—blocking sound principles are used to contain sound within a space; this is best achieved through hard surfaces and slab-to-structure walls with a high Sound Transmission Class (STC) rating
  • Cover—covering sound is best achieved through the introduction of a noise source which gently raises the background noise level to “mask” intelligible speech
