Not just the actual sounds, but even the thought of those sounds (fork scraping across the plate) makes me feel an indescribable way on the inside.
In: Biology
These sounds have a high pitch. When you hear something, a small membrane in your ear vibrates. How often it vibrates for a specific sound determines it’s pitch.
High pitched sounds trigger not only the part of our brain that perceives sounds but also the amygdala, our emotional center, which triggers our fight-or-flight response, our survival instinct.
We aren’t 100% why these sounds trigger the amygdala but it’s probably related to the fact that the sounds are similar in pitch to a human scream. Way back, a scream often ment a danger to our life. So we probably developed the effects to get in high alert mode when a possible danger exists.
