Generally speaking, hearing consists of three stages: hearing (perceiving) and hearing clearly (discernment), and listening (understanding), these three stages are the relationship of inclusion, such as hearing clearly, it must be heard, and hearing is not necessarily clear. This suggests that the higher the back, the higher the nervous system is involved in the activity.
The inner ear has the ability to distinguish sound signals simply. When the inner ear is damaged, the ability to distinguish hearing is reduced. However, due to the fact that there is enough room for human auditory discrimination, 70% recognition of a passage is enough to ensure that we can understand it, and we do not have to demand 100%.
Therefore, less severe inner ear damage does not cause the patient to completely lose hearing discrimination. The auditory center system has more complex and powerful acoustic signal analysis capabilities. If the auditory center is damaged, the auditory recognition ability will be significantly reduced.
When entering a noisy environment, because the speech signal itself becomes indistinct, it is more difficult for people with normal hearing to sound, and patients with hearing loss are unable to hear clearly; A similar situation can occur when the signal is too quiet. For example, the TV is so quiet that we can't hear it clearly. Unfortunately, most patients with sensorineural hearing loss have damage to the inner ear and auditory center, but the degree is different, and the more severe the hearing loss, the worse the ability to discriminate, except for the auditory nerve case.
As a result, most people with sensorineural hearing loss complain of hearing but not hearing clearly. In addition, the central nervous system of the elderly is degenerated, the brain's ability to process information is weakened, and the recognition ability of the elderly is also poor compared to younger people with the same degree of hearing loss. It is more common to be unable to hear clearly and not understand.
