Airborne sounds are sound waves which travel through the air. Flanking noises travel from walls to ceilings, through floors and under walls. It can be difficult to control flanking noise and it takes time.

Basics of Sound Transmission

Sound is a wave of pressure that travels through the air. It can be heard by the human ear but cannot be seen or felt. The wavelength of sound waves (the size and span of the waves ).).

The distance they are from each other determines the frequency of sound waves. But sound waves can still be heard from 17 to 17 meters away. The distance between the speakers is not the only factor that will determine how loud they sound. The volume of the speakers will drop if the room is larger and there are more people.

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

Sound waves may be controlled by using materials that absorb and block transmission.

A calm home will average 40dB. Noisy homes will have a level over 100dB. Material will be more effective when the number is greater.

Considerations for Your Home

A quiet home should have a higher rating than STC40. STC 56 should apply to bathrooms and living areas. STC 60 should refer to kitchens.

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. We have some amazing tips for soundproofing your house if you are new to construction.
There are many things you can do to ensure that your soundproofing job is done correctly. One of these is sound insulation. But what does it do?
