Can 20-year-old mild deafness recover
Deafness can be divided into conductive deafness, neurological deafness and mixed deafness. If neurological deafness has not recovered for more than half a year, it is less likely to consider recovery. It is recommended to actively check pure tone audiometry and acoustic impedance. If neurological deafness is, it is also necessary to distinguish between low-frequency speech frequency and high-frequency hearing loss. Generally, low-frequency decline has the possibility of recovery.
