Hearing Impairments

Measuring hearing: the audiogram -air versus bone conduction

Deficits of up to 15 dB are ignored

1. Conductive deafness -otosclerosis -otitis media -cholestatoma

1. Conductive deafness -otosclerosis -otitis media -cholestatoma (Meniere’s disease)

2. Nerve deafness (sensorineural hearing loss) -Presbycusis (auditory example)

2. Nerve deafness (sensorineural hearing loss) -Presbycusis -Tinnitus (auditory example)

2. Nerve deafness (sensorineural hearing loss) -Presbycusis -Tinnitus -loudness recruitment -pathological adaptation
