NSF SCIENCE360 SUPER SCIENCE REWIND: CELL TALK

In this Super Science Rewind, Charlie and Jordan demonstrate how the cells responsible for relaying information from the ear to the brain adapt to noise levels in an environment. A cell in the auditory nerve exposed to loud sounds for a prolonged period of time can alter its behavior and structure, allowing you to hear new sounds. Remove the background noise and the cell changes again to adapt to the quieter environment.
