Sound in space is what always surrounds us as background music. A person is adapted to local noise, in which he dwells for a long time. For example, someone lives near the airport and no longer notices the sound of an airplane flying by, or someone living near a railway constantly hears the sound of wheels. A person from the countryside will acutely feel the difference between suburban silence and city traffic noise, construction site sounds, sharp and sudden sounds that fill big cities. The environment itself, the locality, the change of time and day determine the local dialect of sounds that affect the psychological and emotional state of a person.
