Which description applies to a total deaf disorder?

A total deaf disorder is characterized by a complete inability to hear any sounds. This level of hearing loss means that individuals do not perceive auditory stimuli, which significantly impacts their ability to communicate and navigate their environment through sound. In cases of total deafness, individuals often rely heavily on visual cues, such as lip reading and sign language, for communication.

The other options describe varying degrees of hearing loss or alternative methods of sound perception, which do not align with the definition of total deafness. Hearing aids may assist individuals with partial hearing loss but do not benefit those who are completely deaf. Similarly, mild hearing loss indicates some level of auditory perception, and interpreting speech sounds through vibrations is a technique more common among those with residual hearing ability rather than total deafness.
