Noise is an unavoidable part of our everyday lives and unfortunately, it can be harmful to our hearing. However, as it can be difficult to avoid on occasion, people usually become annoyed and irritated when exposed to it. The human mind is programmed to protect itself from any harm and to become cautious and anxious when it picks up danger. Many sounds of a particular frequency and decibel level are perceived by the brain as a potential attack (such as alarms, sirens or horns) and evoke a sense of emergency. That elevates the adrenaline level and increases the heart rate. If the danger is not real, as it is with many noises that we experience every day,
this leads to irritation.
