The present study investigates the test-retest reliability of category loudness scaling with pure tones for each of the scaling categories: 'very soft', 'soft', 'OK', 'loud', 'very loud' and 'too loud' at the audiometric frequencies 0.5, 1 kHz, 2 kHz and 4 kHz. Category loudness scaling at two sessions separated by between 1 and 4 weeks was obtained from 16 normal-hearing subjects who all had normal otoscopy, present acoustic reflexes at audiometric frequencies 0.5-4 kHz and middle ear pressure within +/-50 daPa. Intra-subject between-session reliability was found not to be frequency dependent, and comparison with other studies revealed that reliability is not dependent on the applied stimulus signal. Test-retest reliability varied between the different categories: In the categories 'very soft', 'loud', 'very loud' and 'too loud' the test reliability is in the same range as found for hearing thresholds determination, whereas for the 'soft' and 'OK' categories it is poorer. The greater uncertainty for intermediate levels should be considered when using category loudness scaling, e.g. for calculating hearing aid parameters.
本研究调查了在听力测试频率0.5、1千赫、2千赫和4千赫时，对于“非常轻柔”“轻柔”“正常”“响亮”“非常响亮”和“太响亮”这些响度等级类别，使用纯音进行类别响度标度的重测信度。从16名听力正常的受试者获取了间隔1至4周的两次测试的类别响度标度，这些受试者均具有正常的耳镜检查结果、在0.5至4千赫听力测试频率下有正常的听觉反射且中耳压力在+/-50达帕范围内。发现受试者内的测试间信度不依赖于频率，并且与其他研究的比较表明，信度不依赖于所施加的刺激信号。不同类别之间的重测信度有所不同：在“非常轻柔”“响亮”“非常响亮”和“太响亮”类别中，测试信度与听力阈值测定的信度处于相同范围，而对于“轻柔”和“正常”类别，信度则较差。在使用类别响度标度时，例如用于计算助听器参数时，应考虑中间等级存在的更大不确定性。
