Adults or the elderly mostly suffer from sensorineural and mixed neuropathic hearing loss, resulting in more mid-to-high frequency loss, and decreased speech resolution, which reflects the hearing but inaudibility problems in daily life, and the brain will gradually lose over a long period of time. Many verbal memories require a long time to adapt and recover part of hearing even after wearing hearing aids. This is why we recommend that people with hearing impairment choose hearing aids as soon as possible.Early detection and early intervention are extremely necessary to protect and compensate the existing hearing.
Those factors determine whether we can hear clearly?
In an environment that is too noisy, because the sound signal itself becomes ambiguous, people with normal hearing can’t hear it clearly; a similar situation can occur if the signal is too small.For example, the TV sound is too low, and we normal hearing people can’t hear it.But this is not the whole problem.The inner ear has the ability to analyze acoustic signals.After the inner ear is damaged, the auditory analysis ability will be significantly reduced.But because our auditory discrimination ability has enough leeway, we don’t have to hear 100% clearly to ensure that we understand.Therefore, less serious inner ear damage will not completely deprive the patient of auditory discrimination.The listening center has more important sound signal analysis capabilities.The auditory center is damaged, and the auditory discrimination ability will be worse.
