Why are voices so unique and distinguishable? Even a single word can let you recognize someone.
In: Biology
Our ears are very fancy, they are not like single microphone, but rather set of thousands of microphones called [[“hair cells”]](https://iiif.wellcomecollection.org/image/B0000114.jpg/full/880%2C/0/default.jpg), that allow us to distinguish not only a single sound, but also “whole bouquet” of all sound frequencies that fall into our ear.
Someone talking to us might have a major sound that is dominating in their voice, but it will always be a combination of many different sounds and reflections, that’s also how even with our eyes closed we can recognize if a person is standing in front of us or behind.
