If you say you don't use to hear when people warn you , you have no to cooperate for your Health
The use of headsets has become pervasive in the business world. However, some potentially detrimental health consequences can emerge from using headsets, especially if they are not used and maintained in the optimal manner. This is not meant as a discouragement of their use. Personal and employee health are both very important in the workplace. As long as a few simple precautions are taken, headsets can be used and their benefits taken advantage of without exposing anyone to the possible harmful effects of their use.
Hearing Loss
Anytime a speaker projects sound directly into your ear, there is the potential for hearing damage. The UCLA Ergonomics Division states that the volume of a user's headset is the largest factor in whether or not there is a risk of hearing loss. They suggest that the volume on the headset be kept low enough that someone sitting next to the user cannot overhear the conversation. It is also recommended that users of headsets take breaks of a few minutes every half hour to prevent fatigue of the auditory system.
Germs
The telephone, or the headset that accompanies it, can be one of the most prolific breeding grounds for germs in your office. University of Arizona Professor of Microbiology Charles Gerba did research on the various places where germs congregate in the work environment and found phones and headsets to be far more germ infested than more obvious culprits such as toilet seats. Headsets should be cleaned regularly with a disinfecting product to help reduce the buildup of disease causing germs.
Vocal Strain
Improper use of a headset can cause vocal strain, especially if the person using the headset is talking throughout most of their work day. If the headset has an adjustable microphone, make sure it is positioned so that it picks up a clear signal from your voice without requiring strain to speak. Speaking in a quiet, relaxed manner throughout the day helps to prevent vocal injuries. If the headset is only an earpiece with an attached mic, ensure that the input level is turned up high enough that you don't need to strain your voice.
Radiation
Questions have been raised by many groups regarding the radiation that you could be exposed to when using a Bluetooth headset. In actuality, the amount of radiation emitted from these devices is well under the threshold of what is considered harmful. While studies have still not conclusively shown that even cell phone radiation is harmful, a Bluetooth headset actually reduces the radiation that you are exposed to compared to holding your phone up to your ear. Any radiation in excess of a 1.6 watt per kilogram absorption rate is considered to be unhealthy. Standard Bluetooth headsets only emit enough radiation to be absorbed at a rate of around .001 watts per kilogram.
Do Phone Headsets Cause Earaches?
Phone headsets can play a major role in your workday that you may not even think about. Talking on a Bluetooth headset, for example, can occupy more time than you might think. Most of the time you probably use a headset without any discomfort or medical problems. However, problems stemming from phone headset use are by no means uncommon. The most important issue to determine is whether your discomfort is caused by the sound itself, headset hygiene or the fit or style of headset that you use.
Sound Pressure
The more powerful the speaker inside your headset, the more air pressure is put on your eardrum. Most headphone speaker designs enable some of the pressure to escape from the back or sides, easing the force of the impact, but higher volumes and more sealed designs can lead to barotrauma earaches, which is when the pressure inside the eardrum differs from pressure outside the eardrum, or even tinnitus, a permanent ringing in the ears. In general, keep the volume to your headset as low as possible.
Bacteria
The very things that make headsets work best -- a sealed environment close to the body -- also make them much more likely to promote the growth of bacteria. The good news is that there's very little risk that this will lead to a medical condition, unless you're already susceptible to experiencing ear trouble. Take extra care to keep your headset clean, and regularly replace old headsets and ear pads. Also avoid sharing headsets or headphones or using public headsets such as on planes, and avoid sharing headphones or earbuds.
Ergonomic Issues
Headsets can cause problems even when the eardrum itself isn't being irritated. Referred ear pain can be caused by soreness anywhere in the vicinity of the ear, from the jaws to the top of the head. If you have a poorly-fitting headset, the headband or even the housing of the microphone may cause soreness that extends to the inner ear -- again, especially if you're already prone to earaches or ear infections in general
Recommendations
Earbuds or in-ear headphones are the most likely to cause problems, especially one-size-fits-all designs which force your ear to conform to them, rather than conform to your ears. A better choice would be to switch to on-ear or over-the-ear headset models. The cushioning should be removable for cleaning and replacement, but while soft foam is more comfortable, it's more difficult to clean and sterilize than plastics or vinyl. Obviously, if the earache is recurring or persists for more than a day or two, don't hesitate to seek medical attention.
