Unfortunately, we hear about people who have suffered hearing damage from exposure to (excessively) loud noise all too often. This hearing damage manifests in several ways, e.g. through continuous ringing or humming in the ears. This is the daily reality of over 2 million Dutch people.
Noise can be harmful above 80 dB. For every 3 dB increase in volume, the length of time you can be exposed to it without suffering hearing damage decreases by half. Volumes at a concert soon reach around 103 dB, which means you risk hearing damage after just a few minutes without hearing protection!
