How Does Soundproofing Work?

Noise pollution is a major problem in our society. It's not just the noise that bothers us, but also the lack of sleep and productivity it causes.

Soundproofing is the process of reducing the sound pressure generated by a specified sound source and receptor. One common place noise is annoying is inside the home. 

Often you don't want to keep the volume on your TV or music system too loud because of other people in the house. It would also be helpful to reduce noise pollution for other reasons, like studying.

Here's How Soundproofing Works

Soundproofing is the act of reducing the amount of noise that is transmitted by either airborne or structure-borne vibration. SoundProof Guru is an expert in soundproofing and can advise you on the best way to insulate your walls.

How Soundproofing Works

The following steps will show you how soundproofing works.

Step 01: Ambient Noise

First, you would want to decide where the noise is coming from. For instance, if your neighbor's dog barks all night long, it may be time to try soundproofing.

Also, if there are loud road noises outside your bedroom window every morning while you attempt to sleep in on weekends or during summer break, soundproofing would be a great solution for you.

Step 02: Decibel Levels

Ambient noise is the general noise level in an environment. It's usually expressed in decibels (dB). The higher the dB, the louder the noise. A soundproofing treatment will work best when it's applied to a surface.

Decibel Levels

Step 03: Sound Transmission

When sound waves hit a surface, they cause the material to vibrate. How much it vibrates depends on the stiffness and mass of the material. The higher the stiffness and mass, the more it will vibrate and create noise.

Sound Transmission

One way to stop this vibration is by using a barrier between the sound source and the receptor.

Step 04: Sound Insulation

The insulation contains compressed materials. The closer the molecules are packed together, the more they resist movement from sound waves. This resistance of movement will dampen sound waves and stop them from traveling through.

Sound Insulation

Sometimes these products contain a layer of foil to reflect high-frequency noise back into the source of the noise.

Step 05: Noise Reduction

There are different materials that you can use to absorb sound. Examples of these materials include insulation, drywall, foam rubber, acoustic tiles, and fiberglass batts.

Noise Reduction

These materials also reduce reverberation and echo, which gives you a more pleasant listening experience. Each material has a different resistance to sound vibration. The more the resistance, the less noise passes through it.

Types of Soundproofing

There are three types of soundproofing: noise reducing, noise-absorbing, and noise decoupling.

Types of Soundproofing

Noise Reducing

This type of soundproofing blocks the noise before it can enter the room. It is best used for stopping mid and high-frequency sounds.

Noise-Absorbing

In this type of soundproofing, materials are used to absorb and prevent the sound from being reflected in a room. It is best used for low-frequency sounds.

Noise-Absorbing

Noise Decoupling

This type of soundproofing prevents the noise from entering the room by separating the source and receptor. It is best used for stopping structure-borne noise.

Here Are Some Uses for Soundproofing

A few commonplace examples of where soundproofing is put to use are in houses, recording studios, and cars.

Some Uses for Soundproofing

Houses

One of the most popular places to soundproof is in a home. It's usually done in the walls, ceilings, and floor because these are the areas where noise travels the easiest.

Also, it can be doorways, windows, or any other place you can think of. By reducing the amount of sound that comes in and out of your house, you're not only improving the quality of your life, but you may also be increasing the value of your home.

Recording Studios

When you're trying to record music, keeping out noise is important for recording clean sounds. Soundproofing reduces external noises that influence your recording.

Recording Studios

A commonplace where loud noise needs to be kept out is in a studio. The way soundproofing works here is by reducing the amount of sound that can pass through walls, ceilings, and floors.

Often studios are built with extra insulation in the walls for this reason. Also, they often have special windows that don't vibrate as much when sound is nearby.

Cars

Similar to studios, you want to keep the noise outside of your car when you're trying to listen to music or talk on the phone.

Soundproofing Cars

One way soundproofing works in a car is by using materials that absorb and deflect sound waves. The windshield and windows are designed to minimize the amount of sound that comes into the car.

Conclusion

Soundproofing is a process that uses different materials to reduce the amount of noise that is transmitted. You can improve your quality of life by reducing the amount of noise you're exposed to by using one or more of the above techniques.

Whether it's in your house, studio, or car, soundproofing is a great way to get some peace and quiet. Hope this article was useful and helped you understand how it works!
