| Summary: | The clinical assessment of hearing loss has been transformed and revised in terms of interpreting the characteristics of patterns found in relation to the relative frequency of certain diseases. However, increasing the threshold to 4 kHz as a starting point for hearing loss has shown to be common to different diseases such as noise-induced hearing loss. In noise-induced hearing loss, for example, six mechanisms can be considered: conversion of sound pressure level into hearing level, vascular failure in the cochlear region responsible for hearing at 4 kHz, sound wave propagation velocity is very high and causes the displacement amplitude in the cochlear duct, the structure anatomy of the cochlea causes a collision of fluids in the first curve of the cochlea, characteristics of auricular pavilion resonance and external auditory canal, and sound attenuation of the acoustic reflex. It is hoped that this new paradigm for the different hearing losses will result in a different approach to the physiological changes that affect the auditory system in the form of high-frequency hearing loss. As such, preventing, treating, and avoiding exacerbations are possibilities to be investigated in order to guarantee efficient communication and quality of life for individuals. |
