Soundproofing and Noise Control Frequently Asked Questions

We have listed below some of the most common questions and their answers in hopes of providing basic knowledge related to noise, and noise control products and systems.
What is Noise?
Noise is defined as unwanted sound. Unwanted sound can be hazardous to your hearing or can be simply disturbing, interfering or annoying. Sound does not have to be loud to be unwanted.

Sound Insulation

To understand how different types of soundproofing foam can be used, one must first understand how sound waves and noise levels are measured. The ability of an object to block sound is measured by its Sound Transmission Coefficient (STC) rating, which can range from 0 to 100. A wall with a STC rating of 50, for example, means that noise levels on one side of the wall are 50 decibels higher than on the other side. Sound absorption is measured using the Noise Reduction Coefficient (NRC), which generally falls between 0 and 1. This number shows the amount of sound absorbed by an object, and the higher the NRC value, the more noise is absorbed.

Soundproofing Door – Sound Retardant Doors – Installation Instructions

Sound control can be an important element in some buildings or certain rooms within a building. To meet sound transmission specifications, All Noise Control Door Systems offers a wide range of acoustic doors. Our Acoustic Doors provide many options to choose from

Acoustical Glossary of Terms

A-C
Absorption
The properties of a material composition to convert sound energy into heat thereby reducing the amount of sound energy that can be reflected.
Acoustical
The properties of a material to absorb or reflect sound (adjective) acoustically, (adverb).

How to Stop Sound

Sound is a form of energy that travels as a wave – when that wave hits a barrier as in a sheet of drywall, that barrier will vibrate and cause the air on the other side to vibrate, thus transferring the sound through the wall. There is no one-shot soundproofing technique that will stop noise in its tracks; rather we try to employ a combination of solutions to achieve solid performance.

Acoustical Blankets for Warehouse

Costco Wholesale Corporation contacted All Noise Control to help them find a great solution to their noise control issues they experienced. After discussing their application All Noise Control provided, Costco Wholesale Corporation, with a solution, that would help with the soundproofing, issues by suggesting using the acoustical blankets ANC-AB12
This product has the benefit of both soundproofing and noise barriers. All Noise Control’s ANC-AB12 consists of a non-reinforced 1-lb psf loaded vinyl noise barrier sandwiched between two layers of vinyl-coated fiberglass-cloth faced 1” quilted fiberglass sound absorbers.

What is soundproofing?

Soundproofing is defined as any method of reducing the ability of sound to travel between point A and point B, and is accomplished by the reduction of noise and the absorption of noise. A requirement in many professional recording studios, soundproofing is also becoming popular in residential structures, especially multi-family structures like apartments and condominiums wherein tenants share walls.

Soundproofing is any means of reducing the sound pressure…

Soundproofing is any means of reducing the sound pressure with respect to a specified sound source and receptor. There are several basic approaches to reducing sound: increasing the distance between source and receiver, using noise barriers to block or absorb the energy of the sound waves, using damping structures such as sound baffles, or using active anti-noise sound generators.
