An effective model for noise control is the source, path, and receiver model by Bolt and Ingard. [9] Hazardous noise can be controlled by reducing the noise output at its source, minimizing the noise as it travels along a path to the listener, and providing equipment to the listener or receiver to attenuate the noise.
Noise regulation includes statutes or guidelines relating to sound transmission established by national, state or provincial and municipal levels of government. After the watershed passage of the United States Noise Control Act of 1972, [2] other local and state governments passed further regulations.
Working Environment (Air Pollution, Noise and Vibration) Convention, 1977 is an International Labour Organization Convention. It was established in 1977, with the preamble stating: Having decided upon the adoption of certain proposals with regard to working environment: atmospheric pollution , noise and vibration ,...
The Noise Pollution and Abatement Act of 1972 is a statute of the United ... The initial EPA regulations and programs provided a basis for development of many state ...
The regulations require employers to identify which of their employees may be at risk from hand arm vibration (HAV) dissorders or whole-body vibration (WBV) disorders. [3] Hand arm vibration disorders can be caused by the use of hand-held power tools and can cause painful and disabling disorders of the blood vessels, nerves and joints. [4]
The hierarchy of controls [17] is a guideline for reducing hazardous noise. Before starting a noise reduction program, base noise levels should first be recorded. [18] After this the company can start to eliminate the noise source. If the noise source cannot be eliminated, the company must try to reduce the noise with alternative methods.
Exposure to noise and vibrations is regulated and limits for maritime vessels are given in the ISO standard 6954: Guidelines for permissible mechanical vibrations on board seagoing vessels to protect personnel and crew.
Noise measurement can also be part of a test procedure using white noise, or some other specialized form of test signal.In audio systems and broadcasting, specific methods are used to obtain subjectively valid results in order that different devices and signal paths may be compared regardless of the inconsistent spectral distribution and temporal properties of the noise that they generate.
