How We Localize Sound
Hunters, and the animals we hunt, are designed with two ears, so brains gather different information in each ear with slightly different clues. Because ears are on opposite sides of the head, the sounds heard by either ear will vary in timing, volume, and frequency. These differences are the clues your brain uses to decode a sound’s location.
Let’s say sound is coming from the left:
Variations in Timing: That sound hits the left ear milliseconds before hitting the right ear.
Variations in Loudness: That sound will be slightly louder in the left ear than the right ear.
Variations in Frequency: Because the head blocks some frequencies, the left ear will get all the frequencies, while the right ear gets less frequency information.
At TETRA, our hearing scientists have designed AmpPod technology to maximize your hearing clues in both ears.
