Sound absorption products are designed to reduce echo, reverberation, and noise levels in a room. These materials absorb sound waves, converting the sound energy into heat and minimizing echoes. This process is key to improving sound clarity in spaces like classrooms and open offices. Sound absorption will reduce the reverberation in any type of space to create a quieter, clearer atmosphere. 

Sound absorption can be used in any situation where reverberation is a problem. Examples include offices, village halls, museums, classrooms, meeting rooms and music studios.

What are Echos?

Echo is sound energy repeating around a room. Sound energy will bounce off smooth hard surfaces much in the same way a rubber ball bounces off the ground. Although the direction of the sound changes, the echo sounds the same as the original sound. This creates an amplifying effect and makes everything seem very loud, often making conversation in a room hard to understand. You might have encountered this at some point in a public space where you can barely hear what the person opposite you is saying.

How Sound Absorption Works

When sound waves hit a material, they create friction between the air and the material, converting the sound energy into heat.

Materials Used For Sound Absorption

Common sound-absorbing materials include foam, fiberglass, felt, and other porous materials that trap and dissipate sound waves.

How It's Measured

The sound absorption coefficient (a) indicates how well a material absorbs sound, ranging from 0 (no absorption) to 1 (full absorption).

How Sound Absorption is Affected by Acoustic Panels

• Mass Density: Denser materials absorb low-frequency sounds better but are less effective with high frequencies.

• Thickness: Thicker materials absorb low-frequency sounds more effectively, but thickness has little impact on high frequencies.

• Small Pores: Materials with smaller pores absorb sound better than those with larger pores.

How to Apply Acoustics In An Open Space

To reduce echoes and improve sound clarity in an open space or room, install sound-absorbing panels or angled wall features to help redirect and minimize sound reflection. 

Acoustic Panels can improve environments by: 

• Improving speech intelligibility in a room

• Acoustic panels absorb sound waves, which reduces echoes and makes it easier for people to hear each other. 

• 
  

• Optimizing Room Communication

• Acoustic panels help ensure that people can hear and participate in discussions, which is important for creating an inclusive learning experience. 

• 
  

• Versatility in design

• Acoustic panels come in a variety of colors, sizes, and designs, so schools can easily incorporate them into their existing aesthetic.
