[Göttingen sentence in noise for different audiogram classes].

BACKGROUND: In addition to the standardized Freiburg sentence test in silence validated speech tests in noise are available. They are mainly used to test the benefit of hearing systems in everyday-life situations. In diagnostics tests in noise can also give additional information of the patients' hearing impairment. The determined speech reception threshold (SRT) depends on the degree of hearing loss and the used speech and noise test material. Aim of this study was to analyze the results of the Göttingen sentence test in noise in relation to different audiogram classes.
MATERIAL AND METHODS: The Göttingen sentence test in stationary noise (65 dB) was performed for 135 patients with different degrees of hearing losses. Based on the air-conducted threshold all ears were categorized to an audiogram class by an automated procedure.
RESULTS: For the mild hearing losses the results of the Göttingen sentence test increased with increasing pure-tone-average (PTA) and the values are smaller than 0 dB SNR with a small standard deviation (± 1-2 dB SNR). For the moderate hearing losses values of 5 dB SNR with a standard deviation of 6 dB SNR were achieved on average. Patients with a high hearing loss achieved values higher than 20 dB SNR.
CONCLUSION: For the mild hearing losses the results were located in a small range. However, they can give important information about the patient's hearing impairment mainly appears in a noisy environment. With increasing hearing loss also the reduced hearing in silence affects the results achieved with the Göttingen sentence test in noise. Therefore the hearing in silence has to be taken into account at the interpretation of the results. © Georg Thieme Verlag KG Stuttgart · New York.
