The Benefits of Linear Frequency Lowering for Music
Successful approaches for preserving harmonics in music programs can retain the same overall sound of music for hard-of-hearing people.

Researchers at Uppsala University have created the “first 3D map of the hearing nerve showing where the various sound frequencies are captured,” according to an article on the university's website. Using what is known as synchrotron X-ray imaging, they were able to trace the fine nerve threads and the vibrating auditory organ, the cochlea, and find out exactly how the frequencies of incoming sound are distributed.
The human ear, like those of other mammals, is so extraordinarily sensitive that it can detect sound-wave-induced vibrations of the eardrum that move by less than the width of an atom. Now, researchers at MIT have discovered important new details of how the ear achieves this amazing ability to pick up faint sounds.
