Noise pollution is a major problem in the modern industrialized world. A noisy environment is difficult to work in and possess a health risk as well. Proper environmental noise control is needed to better the acoustic environment. Persons who work in noisy industrial areas should undergo regular medical check-ups to ensure that they have not suffered from hearing impairment.
The management of this pollution is centered on architecture, urban planning, transport and occupational areas. Globally, aircraft and road traffic are the most stubborn sources of pollution. With the exception of electrical vehicle development, very little has been to abate road and aircraft air pollution. Recreational activities may affect people living in neighboring areas by generating amplified sounds and music. This poses a significant challenge in effective control strategies
Different methods have been used to manage interior sound levels. These include party wall designs, exterior walls, and floor and ceiling assemblies. Rooms designed for specific purposes like entertainment halls, recording rooms and auditoria generate sound which can be contained by constructing sound absorbers or baffles. Sound masking as opposed to proofing refers to active addition of sounds to minimize the perception unwanted sounds.
Development of hybrid vehicles in efforts to control road traffic sources will need to attain a market share of about fifty percent to have a significant impact on the streets. Improving tire tread designs for trucks better shielding diesel stacks are some of the ways of curbing noise at source level. Speed control is effective since the minimum sound emissions come from vehicles moving at a speed of at least thirty kilometres per hour.
In the aircraft industry, getting rid of loud engine designs is one of the few measures put in place as a noise control strategy. A number of different flight restrictions are a great potential to improved acoustic environment. This may include preferred use of runways, time of day restrictions and departure flight path. The major setbacks however are flying inconvenience, flight economics and safety.
A number of finishes and materials can be employed in ceiling panels and acoustic walls. A good panel is one that does not interfere with the substrate. Fabric covers are used for effective maximum absorption. The covers may be modified into sound blankets or curtains that are used to cover surfaces or noisy equipment. Moreover, windows that are thicker or double glazed may also serve the same purpose.
Noise from industrial equipment can be reduced by redesigning the machinery to operate in a manner less prone to produce extreme sounds. Additionally, workers can be provided ear protection equipment, shock mounting source equipment and creation of solid barriers. With regard to more conventional office environments, remedies may also involve researching for silent office equipment such as printers and photocopy machines.
A wisely laid out plan for environmental noise control is crucial in eliminating all areas of pollution. In a nutshell, sound management methods include insulation and absorption, vibration isolation and vibration damping. Sound insulation employs large barriers to prevent transmission of sound. In damping, vibration energy is extracted from the thin sheet and dissipating as heat.
