JUST THE FACTS MA'AM JUST THE FACTS W here is most of the damage coming from? Well if you ask someone who does not ride then they may well think that it comes from exhaust noise. Anyone that does ride will tell you that it is the wind buzz that makes the major impact on hearing. Now we as explorers tend to ride longer hours and at various speeds in all kinds of conditions so we do get a greater exposure to the elements. Here are the figures that the Health and Safety people cause legal action against a company for noise levels and what we can expect to be exposed to riding a bike. At 70mph, the legal limit in the UK (at the moment) then the noise level can get to 105dB. If you’ve been on the German playground where all bets are off then you can expect to get 110dB at 100mph and at 120mph you may be looking at 115dB. If you are doing 120mph then it’s also a good idea to check that anything strapped to the back is still there when you get to the border! So we have 105dB at 70 but if you had that at work then the law in the UK would say that if you’re exposed to a noise level of 80dB as a daily or weekly average then you must have Aircraft carrier deck = 140dB training and make hearing protection available, at the company’s cost. At just 85dB average for the day or weekly exposure then the law states that the employer must take reasonable action to reduce the noise. The use of hearing protection becomes mandatory for all. Then the upper limit accepted by the Health and safety body is down as 87dB, above this level no worker can be exposed (taking hearing protection into account). But there we are running along all day with no protection and exposed to upward of 105dB of noise that is generated from wind turbulence. There can be no doubt that this is going to have a detrimental effect on your hearing. The big thing is that it builds up, each tour could make you a little more deaf and there is no ‘cure’ for this, once your hearing is gone, it’s gone! Leaving you with a snazzy hearing aid and perhaps worse… tinnitus!
