Although living conditions have improved now, hearing loss is not uncommon, and many people have this problem. When hearing loss occurs, auditory function declines, which will seriously affect normal life and work.

Do people with hearing problems have the same hearing properties?

People with hearing problems have different causes of hearing loss, so the nature of their hearing will also be different.

If there is a hearing problem, we must intervene in time. Don’t just buy one online for free. This may cause secondary damage to hearing. hurtful. Be sure to go to a professional hearing aid fitting center and let the hearing aid fit you to achieve the best listening effect. Choose the right hearing aid according to your hearing condition to hear better and more comfortably. It is recommended to consult a professional fitting center.

The International Health Organization (WHO-1997) classifies hearing loss as follows:
Average hearing loss of less than or equal to 25 decibels is normal;
Average hearing loss A hearing loss between 26 and 40 decibels is considered mild;
An average hearing loss between 41 and 60 decibels is considered a moderate hearing loss;
An average hearing loss between 61 and 80 decibels is considered a severe hearing loss;

Severe hearing loss is defined as an average hearing loss of 81 decibels or more.

Usually, hearing loss can be divided into three types according to the location and nature of ear lesions:
(1) Conductive hearing loss (conductive deafness): caused by the external ear There are lesions in the middle ear that hinder the sound conduction process and cause hearing loss. Common causes of deafness include external auditory canal obstruction, foreign bodies, inflammation, congenital ear canal atresia, acute and chronic suppurative otitis media, acute and chronic non-suppurative otitis media, congenital malformations, tumors, bullous myringitis, early otosclerosis, etc.
(2) Sensorineural hearing loss (sensorineural deafness, neurosensory deafness): refers to the inability of the cochlear spiral organ to convert sound waves into nerve excitement or the disorder of the nerves and their central pathways and the inability to transmit nerve excitement into the brain; or the brain Cortical center lesions cannot distinguish speech, collectively referred to as sensorineural hearing loss. Such as Meniere's disease, ear drug poisoning, labyrinth syndrome, noise damage, acoustic neuroma, etc. Hearing impairment caused by lesions of the cochlear spiral organ in the inner ear is called sensorineural deafness (clinically, conductive deafness in the inner ear caused by lesions of the endolymph and basilar membrane is also summarized in sensorineural deafness), and nerve conduction pathways occur. Deafness caused by lesions is called neurological deafness. However, it is usually not easy to distinguish the differences between the two clinically, so the two are often combined and called sensorineural deafness. so,Clinically, deafness is caused by ear complications of various acute and chronic infectious diseases, drug or chemical substance poisoning, labyrinthitis, membrane labyrinth hydrops, temporal bone fracture, acoustic neuroma, craniocerebral trauma, cerebrovascular accident, cerebrovascular sclerosis or spasm, etc. and presbycusis can be summarized in sensorineural deafness.
(3) Mixed hearing loss (mixed deafness): There are lesions in both the sound-transmitting and sound-sensing mechanisms. Such as long-term chronic suppurative otitis media, advanced otosclerosis, blast deafness, etc. Supplement: According to the nature of the disease, it is divided into two categories: organic deafness and functional deafness. The former refers to the deafness caused by the abnormal structure of the auditory organ, and the latter refers to the deafness caused by the decline of auditory function.

Hearing, vision, and smell are all very important to the human body. Loss of one of the three will have a great impact on daily life. Therefore, we must pay attention to the care of our senses, especially our hearing. We must stay away from noisy environments and wear less headphones. Both of these aspects can protect our hearing.
