Background sound is key to providing building occupants with improved speech privacy, noise control, and acoustic comfort. When used as the starting point for interior planning, sound masking lets building professionals set the base of background sound throughout a facility, more accurately specify the blocking and absorptive elements used in their design, allowing it to be delivered in a cost-effective manner, and with greater assurance of achieving the intended results.

Learning Objectives

  • Outline the role background sound plays in achieving effective acoustics.
  • Explain how sound masking reduces STCc requirements.
  • Use Speech Privacy Potential (SPP) to achieve project savings.
  • Understand recent changes to ASTM standards related to sound masking.
