A simple screening test for hearing impairment in elderly patients

This study investigated the reliability of simple bedside free-field voice testing in the detection of hearing impairment in patients admitted to a geriatric unit. Sixty-two consecutive admissions were assessed at four graduated levels of loudness by geriatrician and otolaryngologist independently. Pure tone audiometry was then performed blind. Voice testing by both observers was concordant in 88% of all ears and in 100% of ears able to hear a whispered voice (WV) at 2 ft (approximately 0.6 m). The WV at 2 ft was the most discriminant test with a sensitivity of 100%, a specificity of 84% and a predictive value of 92% for hearing impairment likely to benefit from provision of a hearing aid. Free-field voice testing appears a simple, reliable and reproducible test for detecting hearing impairment in elderly patients.
