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 waveform of pressure traveling 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. However, the closer they are the lower the frequency. Between 17 mm and 17 meters, sound waves can be heard. Other factors, aside from the distance between them, determine the volume of their sound. The volume of the speakers will drop if the room is larger and there are more people.

Hertz can be used to measure frequency. Hertz is the unit of frequency.

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 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.

STCs to Consider For Your Home

A quiet home deserves a higher rating then STC40. 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.
