We are constantly exposed to noises from all walks of life

Airborne sounds, sound waves that travel through an airspace, are sounds like vehicles, radios, conversations, and dogs barking. Toys and glass can also fall on the ground, and people may walk on wooden floors. Flanking sounds travel from walls and ceilings to floors and under walls.

Basics of Sound Transmission

Sound is an electromagnetic wave of pressure moving through the air. Although it can be heard with the human ear, it cannot be felt or seen. 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. However, the closer they are the lower the frequency. Between 17 mm and 17 meters, sound waves can be heard. There are many factors that affect how loud the speakers will sound, apart from distance between them. Their volume will be lower if there is more room and people are present.

Hertz is the unit of frequency. It is the sound's tone or musical value. A Tuba's frequency or pitch is 29 Hz while a Tuba's frequency or pitch is 2,000 Hz. Most people can hear between 20 and 20,000 Hz when they are young, but as we age, this ability decreases.

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 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 go for bathrooms and living rooms. STC 33 refers to walls made of 2x4 and 1/2" of drywall on one side.
