Where Does Sound Get Trapped In Your Room?

When you are looking to improve the sound quality in your room, whether it be a home office or boardroom, Gaming room or YouTube studio or a recording studio, understanding where sounds get trapped is the first step to improvement. So, in this article, we discuss where sounds get trapped in a room and which types of sounds get trapped in those locations. Essentially, it boils down to echoes and low-frequency resonance. Another benefit to understanding where sound gets trapped, it will aid you in your process of knowing what to look for when buying acoustic foam. 

How Do Echoes Work?

Echoes in a room occur from sound waves reflecting from different points in a room. Within a room, these echoes reflect off of walls, ceilings, floors, windows, doors, and other objects within a room. The material the sound wave reflects off of impacts the character of the sound wave. This change in the character of the sound waves produces an unpleasant blurring of the overall sound quality in the room.

Additionally, the frequency of the sound also impacts how it echoes within a room. Since low-frequency sound waves have long wavelengths, they require large objects to echo off of. On the other hand, high-frequency sound waves have short wavelengths and therefore can echo off of much smaller objects. So, in the case of a home office or recording studio, it’s unlikely an object will be large enough to reflect low-frequency sounds.

What is Low-Frequency Resonance?

Low-frequency resonance typically occurs in the corners of a room. This means low frequencies tend to build up in the corners of a room resulting in uneven sound quality based on the location of the listener. While other frequencies can also build up in specific areas of a room, low-frequency resonance in the corners of a room are the most prominent. This results in an overall distortion of the sound waves within a room.

When looking at acoustic treatment, understanding echoes and low-frequency resonance and where they get trapped in your room or how they reflect off of surfaces will give you a clearer picture as to which combinations of acoustic foam you will need.
