Deafness is categorized into conductive deafness and sensorineural deafness, etc. In the case of conductive deafness, bone conduction is normal, and the sound of one’s own speech may be partially transmitted through the skull and one is able to hear it. In the case of neurological deafness, the sound of one’s own speech is still not effectively conducted, and the brain is unable to perceive and hear one’s own speech.
Conductive deafness refers to the process of sound transmission from the outside world to the ear, by the outer ear, middle ear and other sound transmission structures lead to auditory dysfunction, the main lesion site in the external auditory canal, middle ear or eardrum. For example, tympanic membrane perforation, chronic suppurative otitis media, auditory ossicular chain fracture and other diseases.
If a person with conductive deafness has normal bone conduction, the sound of their own speech may partly pass through the conduction of the skull and they are able to hear it themselves.
Sensorineural deafness, also known as sensorineural hearing loss or sensorineural deafness, is caused by damage to the cochlear receptors and auditory nerve fibers. In this case, the sound of one’s own speech remains ineffectively conducted and cannot be perceived by the brain.
