Sonex® Mini Acoustic Foam is designed for use in environments where high frequency noise control is required. Its unique sculpted pattern allows for maximum handling of high frequency sound waves. Sonex® Mini Panels are a safety-minded choice for use in machine enclosures and other confined spaces. It can withstand constant temperatures above 300° Fahrenheit, and will char, but not ignite, at temperatures above 1100° Fahrenheit. Sonex® Mini is Class 1 fire-rated and it is 100% fiber-free foam (part #MSO). Sonex® Mini has a minimal depth for use in applications where a thinner acoustic foam is required.


  • Reduces echo and reverberation
  • Improves speech intelligibility
  • Exceptional acoustical performance
  • Smaller convoluted surface pattern
  • Mold-resistant, fire-retardant

  1. Daniel Rosenau

    I bought the sonex 2'x2' 2" thick before
    The sonex mini 2'x4' 1inch thick, I was expecting a little bit depper pattern in the foam that was a little bit of a disappointment.
    I have not put it up yet until next month, when we move to our new home but I believe it will be pretty close to the 2'x2' 2" thick as far as sound quality at least I hope so.

    The color is sprayed on white foam. It’s very easy to crack the color layer.
