Guide to LEED Certification and Acoustic Performance for Soundproofing

Guide to LEED Certification and Acoustic Performance for Soundproofing
July 09, 2025

Whether you are a contractor busy with a new build or an architect planning a multistory apartment, you are most likely designing a LEED-compliant building. Though a Leadership in Energy and Environmental Design (LEED) certification used to focus primarily on sustainability, the acoustics in LEED certification takes sound issues into account.

LEED version 4.1 is performance-based and uses stronger criteria than previous versions for better noise reduction. It includes reducing HVAC noise and allows greater flexibility when choosing soundproofing materials.

Importance of LEED Certification and Why Acoustic Performance Matters

Noise reduction has been increasingly crucial for indoor environmental quality (IEQ) as it increases privacy and contributes to quieter, more comfortable areas. Though noise reduction has been a standard for residential buildings, other types of construction also prioritize soundproofing.

Most modern buildings designed for large groups of people, such as universities, government institutions, and large corporations, will have some acoustic LEED certifications.

How Acoustic Performance Contributes to LEED Points

A project can achieve a LEED acoustic performance certification when it satisfies specific criteria, which include:

  • Reverberation time: Also known as RT60, this criterion minimizes the sound reflecting off walls, floors and other indoor structures.
  • Sound transmission: Sound transmission class, or STC, measures how effectively surfaces block noise transferring from one room to another.
  • Background noise management: Background noise can include voices, HVAC noise and other mechanical disturbances. By reducing background noise, a building can be more pleasant and respectful of all occupants.
  • Speech privacy: Sound masking and voice privacy are crucial for office meetings and healthcare rooms, creating an environment where privacy is protected.

About Kellen Beaver

Soundproof Cow Representative Kellen

Kellen has been a member of the sales team for over a decade. Prior to delving into the soundproofing realm, he was a jack of all trades in the service industry, working both front and back of the house jobs to various degrees. This diversity in experience makes it easy to relate to the needs of a large customer base. He understands noisy environments as well as the importance of aesthetics in a space. Adding something that doesn’t fit the look can be intrusive, so knowing that acoustical needs must fit the interior design is something he’s become very well-versed in. Most of this planning comes from working with both the owner/operators as well as their design team and architects. He has been able to adapt his knowledge in the restaurant industry into projects involving schools, office buildings and large medical facilities when the situation calls for it.
