| Sound is generally fascinating to most people. For example, we would love to hear the sweet chirping of the bird when the day begins, of course the loud sound of the bell telling us that it's time to leave the classroom, or the pleasant music of the ones selling ice cream in our neighborhood. Music, which everyone likes so much, is made up of sound, and these musical pieces engulf us. What is not nice about sound is that it could be noise at times. Although our concepts of pleasant versus intolerable sounds differ, our ears have general standard of what bearable sounds are over the opposite ones. The Occupational Safety and Health Administration (OSHA) has determined that workers exposed to a time-weighted average level of 85 dBA (a decibel level/filter that relates to the inverse of the 40 dB (at 1 kHz) equal-loudness curve) for an eight-hour period are within cautionary noise zones. Even though some might enjoy the sounds of heavy machines, loud factories or bustling work environments it does not mean there is not potential for hearing damage to occur. The conveyor industry is one such business where noise levels must be taken very seriously. These conveyors are present in many workplaces. They are made up of complicated structures that cause their running very noisy. These machines are used to move materials and goods from one area of the factory to another, causing the people working with them to be exposed to a very intolerable noise level. Often regarded as just nothing, the effects of these conveyors should not be taken as if they were nothing. Reading this article will make you know the areas of conveyors that make the operation noisy and means to avoid the problems they may possibly cause. There are very few if any conveyors that can be run in complete silence. With all the working and moving parts that most conveyor processes involve, noise is inevitable. Conveyor rollers, roller bearings and roller shafts are a huge source of noise. Conveyor rolling speed is a huge determining factor as to how much sound is actually created by these devices. Often fabricated out of heavy gage steel, their frames can also be a point of heightened noise. Another part of the conveyor that largely contributes to the sound is the drives. Subparts of the drives include the electronic motors, power trains, gear boxes, bearings, belts, chains, sprockets, mounts and guards, causing towering pitched whines and disturbing vibrations to the people around. Also, hearing problems can be caused by the usage of pneumatic devices. Useless static can also be brought about by drained ports and air compression modules in a pneumatically manipulated conveyor. More so, belt based systems cannot tolerate noise as well. The design, condition and orientation of the belt surface and joints within the belt can make a huge difference in decibel levels as well as how the belt runs across the slider bed or roller bed. Finally the surrounding walls and workspaces can play a major role in noise dampening. Having an appropriate building or place to house a conveyor is as much a key to sound reduction as having the conveyor tuned and built accordingly. Now that we have identified some of the ways conveyors can make noise it is essential to review some of the ways in which these dilemmas can be solved. No company or organization should want their conveyor operators endangered by unnecessary noise. In the spirit of good business and humanity, managers should be doing everything in their power to assure the workplace is not dangerous to employee hearing. One of the most obvious ways to protect people from conveyor noise is to eliminate it all together. Either through removal or an upgrade the loudest conveyors can be quelled in some fashion. By extinguishing, replacing or changing the conveyor at the most extreme noise destinations a lot can be accomplished in regards to environment improvement. If significant resource dedication is not an option, simply maintaining current conveyors through scheduled service checks can be a positive step in the right direction towards the harmful effects of conveyor noise. Making sure all conveyor parts are lubricated properly, moving rationally and are not worn out is an almost sure fire way to keep conveyor noise levels in check. Some of the more complex conveyor noise reduction techniques include vibration isolation and dampening as well as acoustic energy absorption. This can be accomplished through creative shielding or encasing. Those fortunate enough to be starting their journey from scratch should make every attempt in their original designs to eliminate potential noise issues at their source. Conveyors may not be able to hear but they do listen when controlled and maneuvered properly. Humans are sensitive to sound while conveyors are not. Since companies really need conveyors in running their businesses, it is a must that they follow the rules set by OSHA. The employees should be sent on auditory diagnoses regularly. They have to wear audio protectors when they are exposed to 90 dBA level for as long as eight hours. This has been a growing issue-solved only if we do our roles by reducing the noise created by conveyors.
