Each day we are exposed and affected by thousands of different sounds in our residential areas. The use of sound insulation materials to improve comfort can make a big difference in our lives.

Airborne sounds refer to sound waves that travel through air. Flanking noises can travel from walls to ceilings and through floors to under walls. This is difficult to control and 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. Sound waves travel at different speeds depending on their wavelength (the size of waves).

Sound waves travel through air at different wavelengths. However, the closer they are the lower the frequency. Between 17 mm and 17 meters, sound waves can be heard. In addition to the distance between the two speakers, there are other factors that determine how loud they will sound. Their volume will be lower if there is more room and people are present.

Hertz can measure frequency. The Hertz measure frequency.

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

A peaceful home will achieve an average of 40dB. A noisy house will experience over 100dB. It will be more efficient if this number is higher.

Tips and Tricks 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 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.
