What absorbs sound best?

Sound travels in many directions; we can not eliminate the sound, we can still use some materials that can absorb sound, significantly reducing sound vibration and echoes. 

You may now think about what material absorbs the sound best; I can help you by providing the most relevant answers to your queries.

You first need to know how soundproofing materials work. This material acts by stopping sound from entering or leaving a particular room by absorbing a portion of the sonic energy of the sound wave. Then it reduces reverberation time which helps to decrease noise and echoes.

After you know how sound absorbers work, you need to know about the types of sound absorbers. There are mainly three types of sound absorbers:

  • Porous absorbers
  • Membrane (panel) absorbers
  • Resonance absorbers

Porous Sound Absorbers: it contains porous material. This sound absorbing material first stops the sound on its surface and then converts the sound energy into heat, which means only a tiny part of sound energy returns back into the room. Porous Sound Absorbers are the most effective material to treat mid-range frequencies.

Some examples of porous sound absorbers are curtains, carpets, blankets made up of different fabric materials. It also contains mineral wool insulation, open foams, glass fiber, etc.

Membrane (Panel) Absorbers: they are non-rigid and non-porous materials that are most effective in the brass frequency range but not with higher frequencies. These panels don’t feel and look; however, they could absorb more sound. They may be considered in our everyday life like the floor, chairs, tables, windows, closets, doors, and other Furniture all function as panel absorbers. 

Resonance Absorbers: they consist of an acoustic oscillation system. These absorbers have a solid plate on the front end with tight air space behind them. These plates contain perforated plasterboard, metal, or other materials that have holes or other openings.  

The hole present in the absorber acts as a bottleneck that obstructs the sound and locks in into the space located behind the material. 

Some materials absorb sound; some of these materials are a part of our day-to-day life.

  1. Soft Furniture– the first material that absorbs most of the sound is Furniture in your room; soundproofing experts always advise rearranging the Furniture in the best sound absorbing manners.
  2. Thick carpets and rugs- different fabrics absorb different amounts of sound; using a thick carpet on the floor can decrease the footsteps’ noise. You can also use carpets and rugs on the wall to eliminate most of the sound and make your room soundproof.
  3. Wallpapers, paintings, and tapestries- completely bare walls reflect more sound and increase echoes; you can add some wallpapers, paintings, canvas, or tapestries to your room, which may absorb an amount of noise.
  4. Acoustic Window Filmacoustic dampening windows film helps to bring down unfavorable noise. These films reduce the ability of the glass panes to vibrate and effectively absorb more noise.
  5. Sound-absorbing curtains- soundproof curtains have a thick and dense property; this property helps absorb more sound and block them; this is one of the most effective materials for sound absorbing and making a soundproof room.
  6. Sound Blankets and Moving Blankets are the most effective kind of soundproofing fabric; these are thick and heavy and made for portable Furniture.
  7. Acoustic Foam Panels are examples of porous absorbers, which obstruct the sound on its foam surface and preserve the energy to convert it into heat. They are usually 12 by 12 inches of foam panels, primarily used by professionals.
  8. Acoustic Bass Traps- these are similar to acoustic foam panels. Bass traps have two flat sides at a 90-degree angle suitable for a room corner and one side that faces the room.
  9. Sound Absorbing Fabric Panels- these are solid wood frames, and the whole thing is wrapped in fabric such as microsuede or burlap. These panels are 24 inches wide and 36 inches long and have a thickness of 2 inches which helps them absorb the sound.
  10. Sound Absorbing Vocal Recording Panels- last but not least, we have sound-absorbing vocal recording panels; these are foam panels that help to reduce echoes.

How to soundproof a room for recording?

For recording purposes, you need a sound-absorbing room where no other sound can interfere. You will need some equipment that may be expensive but most effective for your recording studio, which provides you professional quality audio.

You can use the following soundproofing ways for your recording room: 

Add Mass:

1- Build a thicker wall-  use thicker drywall for about 1.6cm to absorb most of the sound. You can add a sound isolation barrier inside of the drywall. The sheet blocks on the outside of the wall and conceal it with another layer of drywall.

2- Apply wall padding- after adding mass to the wall and make them denser, you can enhance soundproofing by installing absorbent panels or foam mats that lessen the noise within the room. 

Damping noise and vibrations

After adding mass, you need to do a damping method of soundproofing that throws away kinetic energy from sound waves by preventing them into panels and converting them into heat. You can use green glue between two rigid panels like plywood, drywall, or medium-density fiberboard. It is the most effective damping material in the market.

Decoupling

Decoupling is the process of blocking the travel of sound by isolating the contact points with dense, pliable rubber. Some examples of decoupling are building a floating floor such as Auralex U-Boats, building double walls, isolating layers such as resilience sound clips and resilient channels, and isolating studs from the ceiling, walls, and floors.

Filling Air Gaps

The last method you can use to soundproof a recording room is filling air gaps. There are three products available on Amazon you can buy to fill Air Gaps, Acoustical Caulk, Automatic Door Bottoms, and Foam Gaskets.
