Choosing the Right Commercial Soundproofing Technology
Certain locations have to maintain an acceptable noise level, such as schools, residential complexes, and healthcare facilities. Even industrial and commercial sites have to comply with regulations that guarantee acceptable workplace standards for employees exposed to the constant machinery sounds and other sources of noise pollution. With this in mind, commercial establishments, industries, and businesses have to conform to soundproofing standards that require the adoption of technology to dampen and control the amount of noise within a certain site.
Why Install a Soundproofing System?
Noise pollution can be caused by different sources. Different types of loud noises could be emitted by heavy machinery and industrial equipment or the constant flow of vehicles and transport system. At a certain level and duration, noise can cause health and safety issues within the immediate environment.
For workers, OSHA has set a standard permissible exposure limit (PEL) at 90 dBA for a typical 8 hour day. However, the National Institute for Occupational Safety and Health (NIOSH), has recommended a lower threshold level at 85 dBA. Just to understand what the two ratings sound like, in comparison, a typical construction noise registers at 100 dBA, while classroom conversations are at 70 dBA, according to a NIOSH meter level chart.
Different Types of Soundproofing Technology
Soundproofing technology encompasses different types of applications used for canceling, controlling and damping sound emission from the source. Installing a sound barrier to either absorb or reflect the noise is one methodology. Other sound damping mechanisms involve installing a sound baffle or any acoustic suppression setup.
When it comes to sound barriers, comparisons have been made regarding the noise control capacity of absorptive and reflective walls. The two, which are typical sound barrier material options, differ in how they treat noise emissions. An absorptive barrier is made out of a permeable … Read More ...
