Using light instead of heat, the UV curing process is based on a photochemical reaction. Liquid monomers and oligomers are mixed with a small percent of photoinitiators, and then exposed to UV energy. In a few seconds, the products - inks, coatings or adhesives instantly harden.
(more on hair cells on the next page) Roughly in parallel with the row of 3,500 inner hair cells, three rows of outer hair cells (OHCâs) are situated along the same membrane. The main function of the inner hair cells is to pick up the membraneâs vibrations (like a microphone). The main function of the outer hair cells is to feed back mechanical energy to the membrane in order to amplify the resonance peaks, actively increasing the systemâs sensitivity by up to 60dB(*4C).
But it's certain that the loss of hair cells is what diminishes hearing the most. Hair cells are part of the inner ear that help transmit impulses to a nerve that transfers them to your brain for processing. Nerve damage, injury, exposure to loud noise, and certain medications can cause hair cell loss.earing loss is one of the most common complaints of getting older, especially for men, who are more prone to hearing loss at any age. Aging produces a progressive hearing loss at all frequencies, known as presbycusis.
