- Deaf people develop keener senses of observation, feeling, taste, and smell to compensate for their loss of hearing. Deaf persons process both touch and visual stimuli much more than hearing individuals do.
- Hearing loss may be inherited, caused by maternal rubella or complications at birth, certain infectious diseases such as meningitis, chronic ear infections, use of toxic drugs, exposure to excessive noise and ageing.
- Half of all cases of hearing loss are avoidable through primary prevention.
- People with hearing loss can benefit from devices such as hearing aids, assistive devices and cochlear implants, and from captioning, sign language training, educational and social support.
- Employment opportunities for deaf and hearing impaired people are significantly less than for hearing applicants.
