Every day, we are exposed to thousands of different noises in residential areas. These noises may be heard as impact, airborne, or flanking sounds. Sound frequencies in the 1000 Hz range are most noticeable to us. Sound insulation materials can be used to improve our comfort and our health.

Airborne sounds are sound waves that travel through the air. Examples of airborne sounds are vehicles, radio, conversations and dogs barking, while toys and glass falling on the ground and people walking on a wooden flooring are examples. Flanking sounds travel from walls and ceilings to floors and under walls.

Understanding the Basics Of Sound Transmission

Sound is an electromagnetic wave of pressure moving through the air. It can be heard by the human ear but cannot be seen or felt. Sound waves travel at different speeds depending on their wavelength (the size of waves).

The distance they are from each other determines the frequency of sound waves. The frequency of sound waves is lower if they are closer together. The distance between the speakers is not the only factor that will determine how loud they sound. The larger the room, and the more people in it, the lower their volume.

Hertz can be used to measure frequency. Hertz can be used to measure frequency.

Sound waves can be controlled by materials that absorb or block their transmission.

A quiet home will average 40dB. A noisy home will have a level of over 100dB. The material will be more effective if the number is higher.

STCs to Consider in Your Home

A quiet home should have a higher rating than STC40. STC 56 should be for bathrooms and living areas. STC 60 should go for bathrooms and living rooms. STC 33 refers to walls made of 2x4 and 1/2" of drywall on one side.

Insulation Noise Reduction

Before you start building, soundproof your house. If you're just beginning a construction project and don't know how to soundproof your home, we can give you some great tips.
There are tons of different things that can be done to make sure you get a quality soundproofing job. What is sound insulation? Because it reduces noise and unwanted vibrations, sound insulation is an important part of any home or building. Poor soundproofing can cause problems for people who live in homes that have poor soundproofing.
Sound Dampening

Acoustic insulation is 80. Acoustic insulation is 80.

Insulation improves the value and energy efficiency of your home. Drywall reduces noise in your home.

The wall is supported by steel beams. Sound insulation increases by 49% when 1" is replaced with 5/8".


On the other hand, the soundproofing industry is dominated by 2 types of products: drywall and fiberglass. Although drywall is mainly used in older homes it can still be a great choice for homeowners who wish to improve their home's energy efficiency. Fiberglass insulation is more in demand because of its ability lower noise levels and improve energy efficiency.

Insulation can come in two types: acoustic and mechanical. To absorb sound waves and prevent vibrations affecting sensitive areas like floors or windowsills, mechanical insulation is foam, metal-studs and steel beams. It sounds easy enough, just add insulation! How do you choose the right type?

To make walls, ceilings, floors, or furniture quieter, sound-absorbing materials can be used. These materials are made of metal, foam, rubber, plastic and rubber. They are light and porous and trap sound waves.

Sound blocks are usually thick and heavy materials that reflect sound waves. They transmit less noise.

To reduce noise transfer from different rooms, isolation walls are used. Double-studs prevent sound from being transferred between rooms. Clips are used for isolating walls from one another.

Different Types Of Insulation

The mineral wool can be used to insulate. This material absorbs sound and vibrations from both airborne and impact sources.

Fiberglass is an insulation type that is used for insulate homes.

Sound Control Foam Insulation is a type of polyurethane foam spray foam that is applied to walls to insulate a space. It has a high level of soundproofing and can reduce noise by as much as 90%
