Types of Sound Absorbers
Within a space, sound-absorbing materials use their acoustic characteristics rather than their bulk to absorb echo.
Scientifically speaking, there can be three main types of sound absorbers which include:
- Porous absorbers
- Membrane (panel) absorbers
- Resonance absorbers
While each of these types of sound absorbers works in their own unique way, they all serve the same purpose – to reduce the amount of noise within a space.
1- Porous Absorbers
Porous absorbers are made up of small pores or holes that help to trap air and sound waves.
One of the most popular materials used for porous absorbers is fiberglass, as it is lightweight and easy to work with.
Other materials used for porous absorbers include:
- PVC foam
When sound waves hit a porous absorber, the air within the pores is set into vibration.
This causes the sound waves to lose energy and be absorbed by the material.
Porous absorbers are most effective at absorbing low and mid-frequency sounds.
They are often used in recording studios, offices, and other environments where noise reduction is important.
2- Membrane (Panel) Absorbers
Membrane or panel absorbers are made up of a thin sheet of material that is stretched over a frame.
The most common type of membrane absorber is the acoustic panel.
Acoustic panels are used in a variety of settings, including:
- Recording studios
- Home theaters
When sound waves hit a membrane absorber, the thin sheet of material vibrates. This vibration causes the sound waves to lose energy and be absorbed by the material.
Membrane absorbers are most effective at absorbing mid-frequency sounds.
They are often used in environments where noise reduction is important.
3- Resonance Absorbers
Resonance absorbers are made up of a material that is tuned to absorb a specific frequency range.
The most common type of resonance absorber is the bass trap. Bass traps are used in a variety of settings, including:
- Recording studios
- Home theaters
When sound waves hit a resonance absorber, the material vibrates. This vibration causes the sound waves to lose energy and be absorbed by the material.
Resonance absorbers are most effective at absorbing low-frequency sounds. They are often used in environments where noise reduction is important.
Different Types of Natural Sound Dampening Materials
Sound waves are a type of energy that travels through the air, or any other medium, as a vibration of pressure waves.
When these waves reach the ear, they cause the eardrum to vibrate, which the brain interprets as sound.
There are a variety of different types of natural sound-absorbing materials available on the market that can be used for sound absorption to reduce noise pollution.
Some materials are more effective than others, and some have unique benefits that make them well-suited for specific applications.
Here is a list of some of the best natural sound-absorbing materials:
