It is generally believed that the hearing of the left ear is 5 meters and that of the right ear is 5 meters. The way to detect hearing by distance is voice detection, which belongs to coarse screening and is generally used for hearing screening in physical examination.
The hearing of the left and right ears is normal when it reaches about five meters. If the hearing of the left and right ears is less than five meters, it may be that the hearing system is damaged, which leads to hearing loss, so it is necessary to check and treat it in time. There are many reasons for hearing loss. If the earwax in the ear is not cleaned in time for a long time, it will block the ear canal, affect the hearing conduction and cause hearing loss. It is recommended to clean ear secretions regularly, but not excessively. If there is suppurative otitis media in the ear, suppuration will cause perforation of tympanic membrane. If the auditory nerve is damaged, it will also cause hearing loss. If you have hearing loss, you should seek medical advice in time.
