In ancient Rome, rules existed as to the noise emitted from the ironed wheels of wagons which battered the stones on the pavement, causing disruption of sleep and annoyance to the Romans. In Medieval Europe, horse carriages and horse back riding were not allowed during night time in certain cities to ensure a peaceful sleep for the inhabitants. However, the noise problems of the past are incomparable ...

Apart from hearing loss there are many other effects of excessive noise. Speech interference: In an extra-noisy environment it’s hard to hear people talk – and that’s a safety hazard in itself. Annoyance: Unpleasant sounds, particularly sudden and uneven ones, may cause fear, anger and emotional wear and tear. Inefficiency: Noise may cause fatigue or distract attention from demanding or difficult tasks. These all add up to ...

In engineering, noise is defined as a signal that interferes with the detection of or quality of another signal.

As with other forms of energy pollution (such as heat and light pollution), noise pollution contaminants are not physical particles, but rather waves that interfere with naturally-occurring waves of a similar type in the same environment. Thus, the definition of noise pollution is open to debate, and there is no clear border as to which sounds may constitute noise pollution. ...
