Methods Utilized In Industrial Noise Control In Florida

By Jayne Rutledge


Industrial noise regulation is ideal to reduce the negative impacts of noise to the environment and human health. With the enhanced technology, various methods have been developed to address the subject of sound pollution in the industrial areas. For manufacturers or businesses who deal with bulk machines that produce high levels of sound, it is important to know some of the main practices used for industrial noise control in Florida.

Sound-isolation is the practice of using barriers like deadening materials to limit the transfer of sound from certain areas. These are for instance thermal insulation materials like hardwood, glass, bricks, cellulose, fiberglass and polyethylene that prevent the transfer of sound by convection, conduction and radiation. Sound-isolation materials are either structural or non-structural and can be impermeable, incombustible and resilient to damages.

Another useful method is to use acoustic damping materials like actuators, sensors, regulating systems, mechanical springs and rubber pads. These are usually mounted on machine components like the rotary shafts and motors to keep the sound housed within the devices. The materials used have varied sizes, durability and shapes.

Nonmetallic materials can also be used to reduce sound vibration and pollution. This can be done by using nonmetallic materials such as plastic materials rather than metal products. It can also be done by installing hermetic sealers, which creates a vacuum, which bars the sound transmission.

Unwanted sound can also be absorbed to reduce pollution. Various mechanisms that absorb unnecessary sound waves would be used in recording studios to ensure clear sound provision is achieved. The main apparatus for doing this are anechoic chambers, energy absorbers, acoustic tiles and dropped ceilings.

Resonance reduction is the technique of reducing sound pollution due to uneven resonances. Resonance-control materials are made to reduce the excessive sound that would occur when the oscillation frequencies in certain devices would vary greatly. This can be done by coating metals or glasses with certain materials, which reduce and enclose such sounds averting their movement.

Electronic sound adjusting mechanisms are used to stop sound transfer by interfering with the movement of resonance waves to cause wave displacement. In order to achieve this, an active sound generating device like a loudspeaker is used to neutralize the ambient sound in certain areas. Designers would for instance install sensors, electronics and computers with these mechanisms to minimize the sound pollution by such devices.

Many of these techniques for industrial noise control in Florida rely on the phenomena of generating a sound barrier to the sound waves or form an absorbing mechanism that traps the sound averting its transmission. The substantial aspect of controlling occupational sound pollution is to provide a conducive environment for the workers and reduce some health effects which can result due to excessive sound production. It is important to know these techniques to ensure the safety of your staff and increase your company productivity.
