Most people would associate noise with planes, trains, road traffic, construction sites or even a factory. Rarely do we think about noise levels from recreational activities. Actually, I think we spend so much effort mitigating the former, that we forget that recreational activities can also cause hearing damage. In fact, may people inadvertantly expose themselves to high levels of noise during recreational activities. So you might be protected at work, but your activities might effect you.....
What type of activities are we talking about?
a) Music in clubs and concerts - I couldn't agree more on this point. I go to a charismatic church and they have a band and all. It's more like a rock concert! I have to stuff tissue (though, probably not effective) in my ears.
b) Sound in cinemas - According to IOA, films which rely on special effects are more liekly to have higher noise levels with average levels of 78dB(A) over a 3 hour period. That's like having a tractor in your house for 3 hours.
c) Personal music systems - Well, I get really annoyed by people who have their mp3s on full blast to drown out the background noise on the train. Not only is it annoying for everyone else to listen to their music, but they're getting ear damage. According to an Australian study in Sydney, sound levels from their mp3s was on average 79.8dB. 25% of listeners exceeded the Australian work exposure criterion of 85dB!
d) Motor sports - I'm thinking F1 here, and with the next Singapore F1 in Sep, a lot of Singaporeans (well, those who can afford the tickets!) will be exposed to noise from the vroom vroom. Those who can afford seats with the best views will definitely be exposed to noise from the revving, racing, and amplified music. Hamilton and co will be protected by their state of the art hearing protection, but I don't think ear plugs for the patrons will be as effective. According to IOA, a spectator could be exposed to around 90dB(A)!!
e) Car stereo systems - You know who you are! Those of you who like to drive round with the window down and have your stereo on full blast, as if we didn't know you were there. On full blast, it can go up to 104dB(A)!!
