Objective: The elderly hearing in nursing hospital is important for care giving and communication with their family. This study aims to investigate the elderly hearing in the nursing hospital with the otoacoustic emission (OAE).
Participants & Method: 58 of whom aged from 65 to 91 were analyzed for the results. The signal-to- noise ratio (SNR) was used for transient evoked OAE (TEOAE) and distortion product OAE (DPOAE). OAE lower than 5 ㏈ SNR at speech and high frequency range was categorized to suspicious hearing loss.
Results: It was impossible to evaluate 10.53 % and 13.16% of all participants because it was to have issues in the external and middle ear, and brain problems. The suspicious rate at TEOAE was 31.03, 8.62, 10.34, 48.28, 53.45 % at right ear and 39.66, 12.07, 13.79, 41.38, 67.24 % at left ear in 1000, 1414, 2000, 2828, and 4000 Hz. The mean of speech and high-frequency range were observed to be 15.52, 55.17 % at right ear, 15.52, 48.28 % at left ear. The dB SNR at speech range in the 60s, 70s, and 80s were significantly decreased to 16.1, 13.41, and 8.28 dB SNR, on average.
Conclusion: The SNR of TEOAE was significantly lower in the high-pitched range than in the speech range according to frequency and showed a tendency to worsen with age. For hearing screening in the elderly, TEOAE is more useful than DPOAE with a higher referral rate of 81.03~98.28 %.
