Airborne sounds can be described as sound waves that travel through space. Flanking sounds travel from walls and ceilings to floors and under walls.

Understanding Basics Of Sound Transmission

Sound is a waveform of pressure traveling through the air. Although sound can be heard by the human ear, they cannot be seen and felt. The wavelength of sound waves (the size and span of the waves ).).

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. But sound waves can still be heard from 17 to 17 meters away. 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 to measure frequency. It can be measured in Hertz.

Sound waves are controlled by materials that absorb them or block their transmission. Fiberglass absorbs sound more efficiently than other materials, due to 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.

Considerations for Your Home

A quiet home should receive a higher rating than STC40. Ceilings, walls, and floors should be rated at STC50 or higher. STC 52 is the minimum rating required for bedrooms. STC 56 is for bathrooms and living area. STC 60 should be for kitchens. STC 33 applies to a wall of 2x4 with 1/2" of drywall on either side.
