Noise originates in all sorts of ways and from a multitude of sources. Noise can be defined as any unwanted or offensive sounds that unreasonably intrude into and disturb our daily lives. But in some situations a sound can distract us, break our concentration or, if it’s very loud, even harm us. When this happens, the sound becomes unwanted noise, and it can negatively affect both our physical and mental health. Sound is an important part of everyday life: for communication, for enjoyment or for alerting us to danger. Even in a quiet building, you might be able to hear an air conditioner humming, phones ringing or a clock ticking. If you’re outside, you can likely hear a range of sounds―the wind, traffic or snippets of conversations. Close your eyes for a moment and listen to the world around you.
