Did you know that the sound from a heavy truck moving down the road – approximately 85dB (decibel) – can have an adverse effect on your health?

How about ambulance and police sirens, or the loud ‘hum’ of traffic on a nearby expressway? What about low-flying airplanes, with their engines blaring in your ear drums?
