Whenever anything involving radiations is invented by the scientific community, health concerns regarding this product are immediately raised. Whether this radiation is within the safe range of the radiation spectrum? Will this radiation be harmful to any part of the body in the long run? Have strict measures been taken to ensure the safety of users before releasing the product into the market for regular use? Quite the same type questions are raised by frequent users of Bluetooth Headsets. Can prolonged use of Bluetooth headsets damage the eardrum or any other part of the human ear? Are the radio waves emitted by these headsets harmful at such a close range?
As long as listening devices are concerned, wireless or not all headsets should not be utilized at high volume levels. Still, studies have indicated that ear buds are more likely to trigger hearing problems as compared to normal wired headphones. Ear buds being nearer to the ear drum have more capability to do damage than traditional headphones. This is one main hazard of Bluetooth headsets rectified by maintaining a sensible volume, neither high nor low. High volumes make you less aware of your surroundings which a risk in itself. Less frequent use is also advisable. Doctors suggest using headsets that block down external noise so that the user is not driven towards increasing the volume level. Many models of Bluetooth headsets like Jaybird JF3 and Sony DRBT100CX are external soundproof headsets making sound clearer even at a low volume.
Being wireless in nature Bluetooth headsets are definitely to emit a certain type of radiation in order to communicate with the device it is synced with whether mobile or computer. The concern in this matter is that the Bluetooth radio is situated right next to the wearer’s head which obviously would be the receptor of most of the radiation emitted, being directly in line. Does this make Bluetooth headsets dangerous? The U.S government after great research has established a limit for assimilation speed (SAR) of all consumer wireless gadgets which is 1.6 maximum. An average Bluetooth radio produces a SAR of 0.001 watts for every kg. This level is good enough being within limit. Also it is way too low than the SAR emitted by a regular cell phone. The low amount of SAR is because the Bluetooth is of a very low power and also its usage short range as compared to other wireless devices emitting such radiations for example a mobile phone has to emit enough amount of radiation to reach the nearest mobile tower. This makes it a long range device and naturally because of that it has to emit more radiations. It can therefore safe to conclude that radiations emitted by wireless headsets are insignificant and hence not a health issue.
