Echo vs. Reverberation

Echo vs. Reverberation
June 15, 2018

When you find yourself standing in a long hallway and decide to shout out your name, you might just hear your name repeated back in waves. This return of noise is an example of echo. The sound reflects back to the listener as the frequencies bounce off hard objects such as ceilings and walls. The sound of a humming guitar string that continues after plucking is referred to as “reverberation.”

While you might think reverberation is just a fancy way of referencing an echo, it’s not. To find out the difference between reverb and echo, you must first have a general understanding of each sound effect.

What Is Reverberation?

Do you ever find yourself singing in the shower and gaining a sense of confidence at your seemingly improving voice? There’s a reason why most people love to sing in the shower: it’s packed with reverberation!

It’s easy to see how people mistakenly confuse reverbs for echoes. However, reverberation is entirely different. When you sing in the shower, your vocal notes don’t ring out in repetition. Instead, your singing produces a more desirable sound because it mingles with the other sounds bouncing off the hard surfaces which surround you.

Many musical producers create synthetic or artificial reverbs that they manually add to a song after recording to optimize the sound produced. In other surroundings, however, reverberation generates unnecessary sounds that can provide excess noise.

Where Can You Hear Reverberations

How an Echo Differs from Reverberation

When you were a kid, you likely enjoyed yelling your name in a place, such as a valley, where you could anticipate hearing your name repeated back to you in an echoing form. Unlike reverberations, an echo takes longer to return back to our hearing. The sound is not altered or added to, but instead repeated after bouncing off a hard surface such as a wall.

Anytime you hear an echo, the repeated noise sounds like a fainter version of the original utterance or noise. You can measure an echo based on the number of seconds that pass between each repeated sound.

The Difference Between Echo and Reverberation

So, what is the difference between echo and reverberation? When we hear reverberation, it sounds like a continuous sound, while when we hear echo, it sounds like the same sound repeated multiple times. Both result from sound waves bouncing off objects around you, but reverberation will sound like one sound whereas echo will sound like several individual sounds.

Echo vs Reverberation

A Common Result of Reflected Noise

While they produce varying results, both echo and reverberation are byproducts of the reflection of sound. In both scenarios, noise reflects off a hard or solid surface in a way that alters the original sound. The primary component that differentiates the two is the amount of time that passes between each repeated interval.

Soundproofing With Echoes and Reverbs

At times, reverb is a desirable outcome that enhances musical production. If you want to limit the amount of reverberation in your space, however, opt for an acoustical foam product instead. Foams absorb the sound to increase the sound dampening properties of your area, in effect reducing the amount of reverberation that affects your sound quality.

When echo is an issue instead, opt for our Vibra Block Sound Deadening Materials to provide added protection against unwanted sounds. Our acoustical foam is also an excellent solution that reduces echoes as well as reverberation.

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.
