How Sound Attenuation Contributes to Sustainability Goals

Did you know that sound control can contribute towards sustainability certifications for a building? Yes, it’s true! Energy efficiency and materials content may overshadow acoustic properties as sources of sustainability credits, but sound control measures can contribute to meeting health and comfort guidelines.

First, it’s important to know which leading sustainability standards you’ll be pursuing, and which include acoustical performance as part of their criteria. For example, LEED for Schools offers specific credits when classrooms incorporate acoustical performance as part of the overall design. See page 5 of LEED Certification Contribution document. Schools have various and specific sound control needs – from classrooms, to auditoriums, music rooms, gymnasiums and offices. Specifying hollow metal doors and frames that have high Sound Transmission Class (STC) ratings is key to sound containment, reduction, and insulation. Proper sound control counts towards sustainability credits because it enhances the learning experience, reduces distractions, and facilitates better communication between occupants.

Sound Control for Many Applications

The Steel Door Institute provides key factors for specifying and installing acoustic doors, most notably an understanding of STC ratings and an overview of applications.  STC ratings range from 25, where normal speech can be heard through a wall, to 60+, where a room is virtually soundproof, and there are hollow metal door & frame assemblies available for every level.

In other building types such as healthcare facilities, manufacturing plants, or office workplaces, sound control can contribute toward “green building” standards when spaces positively affect human health and well-being. In public buildings, of course safety and security are of utmost importance, but there’s no need to sacrifice these features in favor of sound attenuation. Due to increasing demand for quiet spaces, open floor plans and privacy, along with the traditional need for sound containment in noise-filled rooms, door manufacturers such as our brands Ceco Door and Curries have developed STC-rated door and frame assemblies for many applications, with options including fire ratings and glass kits.

Benefits of Sound Attenuation

If you’re building or updating a facility, remember to include acoustic performance in the design, for a building that’s super enjoyable to spend time in and meets sustainability goals. By correctly specifying and installing STC-rated door assemblies you won’t miss out on getting sustainability credits for sound attenuation.
