Question

How is audio processed in the brain when receiving sounds with different lengths? I.e. car horn vs bird chirp? How does the brain separate each other when they are intertwined?

In: Biology

Answer 1

Sound is vibrations in the air.
The pitch is determined by frequency.
Multiple frequencies of waves can coexist, so your brain can pickup the frequency of the car horn and the bird chirp and compare them to the memory of the things you’ve heard in the past to seperate them.
