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.
Guide to Sound Isolation and Noise Control
It starts with a simple question, “How can I stop noise from going through this wall?” We have the answer, and it usually involves patching noise leaks in the floor, ceiling joists, windows, and vibrating structures that carry sound waves through solid material.
The term “noise control” refers to both active and passive methods of mitigating unwanted sound in the environment. There are a number of reasons why noise control is an important consideration in both business and private settings, including personal well-being, environmental concerns and legislative issues. However, before proper noise control solutions can be implemented, it is first necessary to determine the source and the underlying causes behind its existence. Once this has been determined, it is then possible to establish an appropriate means of circumventing further problems.
All Noise Control manufactures heavy duty, weather resistant Sound Curtains for outdoor applications. We offer modular panels that can be used for short-term or temporary applications such as construction sites or drilling operations as well as long-term permanent applications such as HVAC systems, dust collectors and generators.
Sound is propagated in air, much like blowing up a large balloon, which expands equally in all directions.
For sound to be generated and heard it must have a source, a medium through which to pass and a receiver.
The loudest sound in recorded history occurred on August 27, 1883, just off the coast of Jakarta, Indonesia.
A volcano on the small island of Krakatoa was undergoing the cataclysmic stage of its months-long eruption. At 10:20 AM the volcano exploded with a sound heard, literally, around the world.
The Difference between Sound Absorption and Sound Blocking
Sound is like water. It doesn’t have a shape or form, but molds itself to its surroundings. And like water, sound can be absorbed by some materials and contained by others.
Sound is vibration transmitted through a medium. When we think and talk about sound, though, we mean those vibrations in air molecules that can be picked up by human ears.
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.
Read a little about what the terms mean or dive rightinto our acoustic products on the right. So what does it all mean? All soundproofing and noise control terms cover a lot of ground in the acoustics and noise control industry. All our products are broken into noise barrier materials – http://www.allnoisecontrol.com/SoundBarriers.cfm and noise absorption materials – http://www.allnoisecontrol.com/NoiseAbsorption.cfm. There are 2 main ways to deal with sound problems.
Noise control is an active or passive means of reducing sound emissions, often incentivised by personal comfort, environmental considerations or legal compliance. Practical and efficient noise control is wholly reliant on an accurate diagnosis of what is causing the noise, which first involves finding the source of noise. Once the source of noise has been found, the focus is reducing the noise at source by engineering means.
