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 noises travel along walls, ceilings, floors, and under walls. It is often difficult to stop them and can take time.

Basics of Sound Transmission

Sound is a waveform of pressure traveling through the air. It can be heard, but it 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. 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 to measure frequency. Hertz is the unit of frequency.

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.

Considerations for Your Home

A quiet home should have a higher rating than STC40. STC 56 should be for bathrooms and living areas. 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

You should soundproof your house before you begin construction. Add more layers of drywall to ensure there's no vibration between rooms. Soundproofing involves making sure the walls have enough space to absorb the sound waves. If you're new to building and are unsure how to soundproof your house we have great tips.
There are many ways to ensure you have a high-quality soundproofing job. What is sound insulation? Sound insulation is an essential feature of any building or home. It helps to reduce noise levels and vibrations throughout the structure.
