Overview: While a loud environment can be distracting, ambient silence can also be an issue. Overhearing private conversations can lead to acoustic dissatisfaction, especially in open offices. Sound masking systems supply a low level of background noise to provide employees to a sense of confidentiality.

80: Sound Reducing Surfaces Intent: To reduce sound reverberation and maintain comfortable sound levels through absorptive ceiling and vertical surfaces

Systems Affected: •Cardiovascular •Endocrine •Nervous

Overview: Unfortunately, proper design and construction is not always enough to achieve acoustic comfort. However, sound reduction treatments can incorporate absorptive surfaces, such as wall panels, ceiling baffles, and ACT tiles, to improve comfort. The noise reduction coefficient (NRC) of a material determines it absorptive properties. The larger the NRC value, the better the material is at absorbing sound.
