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 can be described as sound waves that travel through space. Flanking noises can travel from walls to ceilings and through floors to under walls. This is difficult to control and takes time.

Understanding Basics Of Sound Transmission

Sound is a pressure wave that travels through the air. It is a sound that can be heard but not felt. Sound waves travel at different speeds according to their wavelength (the ).).

Sound waves travel through air at different wavelengths. The frequency is lower for those with shorter wavelengths and vice versa. The frequency of the crests is determined by how far apart they are. 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 is the unit of frequency. It can be measured in Hertz.

Sound waves can easily be controlled using materials that absorb sound waves or block them from being transmitted. Fiberglass absorbs sound waves more effectively than other materials because of its density.

A home that is quiet will have an average level of 40dB. Homes that are noisy will have over 100dB. More effective material will result in greater effectiveness.

STCs to Consider in Your Home

A quiet house should be given a higher rating (STC40) than a noisy one. Bedrooms should be given a minimum rating of STC 52. STC 56 should be for bathrooms and living areas. STC 60 should apply to bathrooms and living spaces. STC33 applies to walls that are 2x4 but have 1/2" of drywall.
