We are constantly exposed to noises from all walks of life

Airborne sounds are sound waves that travel through the air. Examples of airborne sounds are vehicles, radio, conversations and dogs barking, while toys and glass falling on the ground and people walking on a wooden flooring are examples. 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. Although it can be heard with the human ear, it cannot be felt or seen. 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. Sound waves can be heard between 17 mm to 17 meters. You can also determine how loud they will sound by other factors than the distance between speakers. Their volume will be lower if there is more room and people are present.

Hertz can be used as a measurement of frequency. It can be measured in Hertz.

You can control sound waves by using materials that absorb or block them being transmitted. Many insulation materials are available, such as fiberglass, foam and paper. Different insulation materials can absorb different types of sound waves. Fiberglass, for instance, absorbs sound waves better that 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 in 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 be for kitchens. STC 33 applies to a wall of 2x4 with 1/2" of drywall on either side.

Insulation Noise Reduction

Before you start building, soundproof your house. If you're new to building and are unsure how to soundproof your house we have great tips.
There are many different ways you can ensure that you get high quality soundproofing. One of these is sound insulation. But what does it do? Because it reduces noise and unwanted vibrations, sound insulation is an important part of any home or building. The vibration from running motors, vibrating appliances like air conditioners and fans, as well as music played by radios or televisions can all cause issues for those who live in homes with poor soundproofing.
Sound Dampening

Walls can absorb sound and also reflect it. Insulation can reduce the reverberation and make them less annoying. Acoustic insulation can absorb sound waves to reduce the echo effect. An STC for a 2x4 wall is 34. Acoustic insulation is 80.

Insulation improves the value and energy efficiency of your home. Drywall reduces noise in your home.

The drywall's support is provided by steel studs. Sound insulation may be increased up to 49% by using 5/8" instead of 1.
