The electronic "beep" irritates the brain Bashny.Net

By "bipom" we mean notifying a sound signal - such as a car hooter, sound sms or something nasty squeaking, which publishes the washing machine, washing ending. This sound is one of the most common sounds in the modern world. It turns out that the brain perceives it as an irritant.

Natural sounds are different from artificial because it does not break off sharply. To make a sound, it is necessary to transfer kinetic energy from one object to another and cause vibration. For example, hit the stick on the drum. The sound is uneven, and gradually decaying. No matter how loud the sound is not obtained from nature, the brain recognizes it and says - "Well, ok».

Another thing is a flat electronic sound created by using a diffuser and a magnetic coil or a piezoelectric speaker. No matter how important that even a soft "beep" we hear well, because this unnatural sound is released by the brain of the natural flow. "I would not want to hear this stuff" - sighs the brain when your microwave has finished warming up.

Manufacturers know this technique. For example, in most phones, the default ringtone is available that simulates the old phone call: the "dzyyyn!" Gradual decay. It is very popular because even the imitation of natural sounds dearer and more pleasant to the human ear than a digital "beep».
