Everyday, we are exposed a variety of sounds in our surroundings. Sound insulation can be used to increase our comfort.

Airborne sounds can be described as sound waves that travel through space. Flanking noises travel along walls, ceilings, floors, and under walls. It is often difficult to stop them and can take time.

Understanding The Basics Of Sound Transmission

Sound is a pressure wave that travels through the air. Although sound can be heard by the human ear, they cannot be seen and felt. Sound waves travel at different speeds according to their wavelength (the ).).

Sound waves travel through different wavelengths of air. 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. The volume of the speakers will drop if the room is larger and there are more people.

Hertz can be used as a measurement of frequency. The Hertz measure frequency.

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 calm home will average 40dB. Noisy homes will have a level over 100dB. Material will be more effective when the number is greater.

STCs to Consider For Your Home

A quiet home should have a higher rating than STC40. STC 56 should be used for bathrooms and living rooms. STC 60 should refer to kitchens.
