3. External factors: Loud noise, ear trauma, and infections may affect the hearing system and even cause deafness.
4. Ear diseases: for example, otitis media, middle ear malformation, acoustic neuroma, Meniere’s disease, etc., the lesions after aggravation, will cause damage to the hearing, thus inducing deafness.
