Sound Diffusers vs. Acoustic Panels

Sound Diffusers vs. Acoustic Panels
June 13, 2025

When considering acoustic treatments for your space, a few of your options include sound diffusers and acoustic panels. While they may seem similar, these tools serve different purposes. Understanding their differences will help you know which one to use and when to use it, allowing you to solve your sound reduction issues effectively.

How Do Acoustic Panels Work?

Acoustic panels absorb sound. They improve the sound quality of a room by reducing echo and reverberation.

Sound panels are often constructed from dense materials — including acoustic foam, fiberglass, and acoustic cotton — that trap sound waves and convert them into heat. Each material absorbs sound waves at a different level, so your ideal choice will depend on how quiet you want your space to be.

Our Udderly Quiet® Fabric-Wrapped Acoustic Panels, for example, have a dense fiberglass core that allows them to absorb sound across low-, mid-, and high-range frequencies. They also come in a range of customizable fabric wrap finishes to suit your design preferences.

What Is a Sound Diffuser?

Acoustic sound diffusers do not absorb sound. Instead, they reflect sound waves in different directions. Scattering sound waves reduces echo and improves acoustic quality. They are exceptionally helpful in spaces where you want to maintain a natural or vibrant sound, such as in a concert hall or mastering studio.

Acoustic diffusers are also ideal for:

  • Music rooms
  • Recording studios
  • Performance spaces
  • Home listening rooms
  • High-end home theaters

Which One Is Right for Your Space?

The right sound treatment for your space will depend on what you are trying to achieve.

If your room is too loud, go with acoustic panels. They can help you reduce the noise and make voices or music sound more clear. If you have hardwood floors, blank walls or a lot of windows, panels will make a noticeable difference.

On the other hand, sound diffusers help preserve the natural richness of sound in a space without the harsh echo. They are a good choice for audio professionals or anyone trying to keep their space sounding vibrant.

Sometimes, you need both treatments to create a balanced sound field with a combination of sound absorption and diffusion. You can try our perforated acoustic wood panels if you want a solution that reflects and absorbs sound at the same time. The Ecotone panels can be used as part of your interior design. They are available in a variety of finishes, sizes, and patterns, giving you plenty of choices for enhancing the style and ambiance of your space while soundproofing it.

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.
