What Height Should Acoustic Panels Be Hung At?
Updated
Hang acoustic panels with their center at seated ear height, about 4 ft off the floor, so a 2 x 4 ft panel stood on end runs from 2 ft to 6 ft. That recommended height catches seated eye level, 43 to 51 in. in ADA design figures (opens in a new tab), plus standing eye height from 56 in. (5th percentile women) to 69 in. (95th percentile men) in the Army survey data tabled by NC State's Ergonomics Center (opens in a new tab). Your ears sit close to eye level.
Ear height matters because that's where reflections off the side walls, from your speakers or your own voice, bounce back to you. It's why Primacoustic (opens in a new tab) says to mount side-wall panels "at ear and/or speaker height." Adjust for how you use the room:
- Desk or couch: sit in your usual seat, measure from the floor to your ear and center the panel there.
- Standing only: in a vocal booth or at a standing desk, raise the center to about 5 ft, so the panel spans 3 to 7 ft.
- Speakers above your ears: stack a second panel on top of the first so the pair reaches tweeter height too.
For general echo in a living room or office, height matters less than total area, and how many acoustic panels you need does that math. The side-to-side position comes from the mirror trick in where to place acoustic panels.
Hanging height won't change the noise from next door. The soundproof panels guide covers what blocks it, and the soundproof panels FAQ answers more mounting questions.
