![]() ![]() Hearing status can be further assessed with tuning forks. ![]() Screening with the tone-emitting otoscope was the most efficient screening method, as the questionnaire led to unnecessary audiology evaluations with little added benefit in terms of hearing loss detection. Hearing aid use one year after screening was 6 percent in the tone-emitting otoscope group compared with 4 and 7 percent in the questionnaire and dual screening groups, respectively. In a randomized trial of screening strategies in 2305 veterans (mean age 61 years), fewer patients evaluated with a tone-emitting otoscope screened positive (19 percent versus 59 and 64 percent of patients evaluated with questionnaire and dual screening, respectively). In addition to the whispered voice test, tone-emitting otoscopes and/or questionnaires are often used. Whisper a short sequence of letters and numbers and ask the patient to repeat them. To perform a whispered voice test, stand at arm's length behind the patient (to prevent lip reading) and mask hearing in one ear by occluding the ear canal and rubbing the tragus with a circular motion. These include a whispered voice test, tone-emitting otoscope, questionnaires, and tuning forks.Ī systematic review of the whispered voice test concluded that in four studies in adults the sensitivity for hearing impairment was 90 to 100 percent and the specificity was 70 to 87 percent. Office hearing evaluation - There are a variety of methods used to test hearing in the office setting. Many patients, however, will require formal audiologic testing or other specialized tests. (See "Sudden sensorineural hearing loss in adults: Evaluation and management".)ĮXAMINATION - The examination for some patients will involve only simple tests that can be performed in a primary care office. Patients with sudden hearing loss require urgent referral as treatment success is related to early initiation of treatment.
