It is especially accentuated when those affected are in a noisy environment.
The otolaryngology determines multiple causes for hearing loss. Typically there is a problem in the outer ear, middle or a problem in the inner ear.
The pathologies of the outer ear and middle ear transmission cause hearing loss since what is difficult is the coming of sound to the inner ear. In these cases by increasing the amplitude of the sound can be heard comfortably reach.
The pathologies of the inner ear leading to sensorineural hearing loss, which also reduce hearing, cause a failure to understand the language and especially in times when there is background noise.
The vast majority of sensorineural hearing loss stem from the inner ear, particularly in the organ of Corti. Which originate in the auditory nerve in the auditory pathway or in the cerebral cortex are exceptional.
Another interesting fact is that the vast majority of sensorineural hearing loss are genetic, ie they are inherited and also hereditary, here we include what we call presbycusis (hearing loss caused by aging), the most frequent undoubtedly.
The most common symptoms of hearing loss include hearing loss, tinnitus and difficult to understand, but sometimes can be accompanied by vertigo.
