Document Summary

Lowest level at which the patient detects speech at least 50% of the time. Infants and young children: patients with profound hearing loss. Look into patient"s ear: example: occluding cerumen may need to be removed prior to testing, concept of threshold, pure tone threshold: lowest intensity level that a stimulus can be heard 50% of the time, measured in db hl. Instructions to patient: clear and explicit instructions are important and can affect the results, example: telling a patient to respond when he hears a sound vs when he thinks he hears a sound. If there is no response increase to 50 dbhl. If not heard at 50db, sound is increased by 10db until signal is heard: finding threshold, down 10, up 5. If there is no response, a downward arrow is added to the symbol: what can the audiogram tell us, degree (severity) of hearing loss.
