Flanking noises travel through walls and ceilings, under floors, and between floors. It can be hard to control them.

Basics of Sound Transmission

Sound is a pressure wave that travels through the air. It can be heard by the human ear but cannot be seen or felt. Sound waves travel at different speeds according to their wavelength (the ).).

The distance between crests determines how much sound waves travel through the air. They can be heard at distances of 17 mm to 17 m. In addition to the distance between the two speakers, there are other factors that determine how loud they will sound. The louder they will sound, the larger the room and the more people there are,

Hertz can be used as a measurement of frequency. Hertz can be used to 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.

STCs to Consider for Your Home

A quiet home should get a higher rating that STC40. STC 56 should be for bathrooms and living areas. STC 60 should be used for bathrooms and living areas. STC 33 is applicable to walls of 2x4 with 1/2" drywall on each side.

Insulation Noise Reduction
