Airborne sounds are sound waves which travel through the air. Flanking noises travel along walls, ceilings, floors, and under walls. It is often difficult to stop them and can take time.

Basics of Sound Transmission

Sound is a wave of pressure that travels through the air. It is a sound that can be heard but not felt. The wavelength of sound waves (the size and span of the waves ).).

The distance between crests determines how much sound waves travel through the air. Sound waves can be heard between 17 mm to 17 meters. In addition to the distance between the two speakers, there are other factors that determine how loud they will sound. The larger the room, and the more people in it, the lower their volume.


Frequency can be measured in Hertz. The Hertz measure frequency.

You can control sound waves by using materials that absorb or block them being transmitted. Many insulation materials are available, such as fiberglass, foam and paper. Different insulation materials can absorb different types of sound waves. Fiberglass, for instance, absorbs sound waves better that other materials due to its density.

An average home with 40dB will be quiet. On the other hand, a noisy home will have more than 100dB. Higher numbers will make the material more effective.

Considerations for Your Home

A quiet home should have a higher rating than STC40. STC 56 should be used for bathrooms and living rooms. STC 60 should apply to bathrooms and living spaces. STC33 applies to walls that are 2x4 but have 1/2" of drywall.

Insulation Noise Reduction

Before you start construction, soundproof your home. This involves adding more layers to the drywall so that the sound waves are absorbed by the walls. 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 many ways to ensure you have a high-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.

Which type of insulation is best to soundproof?

Fiberglass insulation

What R-value does soundproofing require?

When someone asks about the best R-value for soundproofing materials, they will find that R-13 and R-19 can be referred to as the best. For outside walls, R-13 to R-23 are the most common.


Is a higher R-value a sign of better soundproofing?

Higher R-values indicate more effective insulation. Although insulation is a good way to save energy, soundproofing walls can only be achieved by adding additional insulation. This will not make the walls more noise-dampening.


How effective are insulations for soundproofing.

Foam insulation can deaden sound by up to 80 percent, but you will still get some sound transmission. RetroFoam of Michigan has been helping homeowners dampen sound in their homes or pole barns since 2002, so we understand how the transmission of sound works.
