When land dwelling animals evolved they now had to detect environmental sounds that traveled through the air. This created a special challenge because their inner ears continued to be fluid filled.

We can hear sounds because our ears turn sound vibrations from the air, into signals that are sent to our brain. We can’t hear all levels of sounds. Sound waves with very high frequencies are ...

When an object vibrates it produces a longitudinal wave which travels through air to your ear. For a sound to be heard you need three things: A vibrating object A material for the sound wave to ...

Interaural intensity differences between the two ears are the result of the acoustic shadow created by the head for frequencies in the middle to high frequency range. If, for instance, a sound comes ...

Researchers from the Keck School of Medicine of USC, in collaboration with Baylor College of Medicine in Houston, Texas, used an innovative imaging tool to examine the mouse inner ear and made a ...

In the natural world, however, two physical factors determine the intensity that reaches a listener's ears: the intensity at the given sound source in the environment (which is equivalent to the ...
