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.

Understanding the 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. The wavelength of sound waves (the size and span of the waves ).).

The distance between crests determines how much sound waves travel through the air. Sound waves can be heard between 17 mm to 17 meters. The distance between the speakers is not the only factor that will determine how loud they sound. The larger the room, and the more people in it, the lower their volume.

Hertz is the unit of frequency. It can be measured in Hertz.

Sound waves can be controlled by materials that absorb or block their transmission.

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 deserves a higher rating then STC40. 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.

Insulation Noise Reduction

Before you start construction, soundproof your home. This involves adding more layers to the drywall so that the sound waves are absorbed by the walls. If you don't have any idea what to do, we will share some fantastic tips.
There are tons of different things that can be done to make sure you get a quality soundproofing job. It is important to understand what sound insulation does. Because it reduces noise and unwanted vibrations, sound insulation is an important part of any home or building. Homes with poor soundproofing could be affected by vibrations from fans and running motors as well as vibrations from vibrating appliances such as air conditioners or fans.
