Sound


Intent: The WELL Sound concept aims to bolster occupant health and well-being through the identification and mitigation of acoustical comfort parameters that shape occupant experiences in the built environment.

 

WKU Points Achieved in the Sound Feature


 

Intent: Incorporate strategic planning and mitigation required to prevent general issues of acoustical disturbance from both externally and internally generated noise.

This WELL feature requires strategic interior planning and site zoning to create an acoustical plan that identifies internal and external noise sources that can negatively impact the acoustical environment of interior spaces

  • Label Acoustic Zones: An annotated document is provided that labels specific zones throughout the project floor plan based on loud zones, quiet zones and mixed zones.

Intent: Establish background noise level criteria for enclosed spaces in order to promote best-practice HVAC and façade design techniques and ultimately bolster acoustical comfort within. 

This WELL feature requires design- and performance-based compliance that projects can adhere to in order to facilitate comfortable interior noise levels. This feature can operate in tandem with Feature S01: Sound Mapping by introducing the specific performance thresholds for background noise levels within specified locations as attributed by internal and external noise sources.

  • Limit Background Noise Levels:  Background noise levels in do not exceed average sound pressure levels: Open Workspace 55dBA and 80 dBC.  Enclosed Offices 50dBA and 75 dBC; conference rooms and classrooms 45dBA and 70 dBC

Intent: Increase the level of speech privacy between horizontally adjacent enclosures and highlight design constraints that may hinder acoustical comfort

This WELL feature requires requires design- and performance-based compliance that projects can adhere to in order to bolster acoustical privacy between rooms. This feature can operate in tandem with Feature S01: Sound Mapping by introducing the specific performance metrics of partition acoustical performance criteria and privacy [e.g., Noise Isolation Class (NIC), Sound Insulation (Dw), Speech Privacy Potential (SPP)].

  • Ensure Proper Door Specifications:  Doors which connect private offices, conference rooms, classrooms and dwelling units to other spaces are constructed with non-hollow core door and a minimum STC-30 acoustical performance.

Intent: Design spaces in accordance with comfortable reverberation times that support speech intelligibility and are conducive to focus.

This WELL feature requires steps be taken to address acoustical comfort by assigning requirements for surface finishes and reverberation time depending on the room functionality.

  • Implement Sound Reducing Ceilings Open Workspaces and Enclosed Offices with 0.7 NRC/ αwMin for at least 75% of available ceiling area, Conference Rooms 0.7 NRC/ αwMin for at least 50% of available ceiling area.
