Abstract

Objective: The ability to discriminate natural soundscapes recorded in a temperate terrestrial biome was measured in 15 hearing-impaired (HI) listeners with bilateral, mild to severe sensorineural hearing loss and 15 normal-hearing (NH) controls.

Design: Soundscape discrimination was measured using a three-interval oddity paradigm and the method of constant stimuli. On each trial, sequences of 2-second recordings varying the habitat, season and period of the day were presented diotically at a nominal SPL of 60 or 80 dB.

Results: Discrimination scores were above chance level for both groups, but they were poorer for HI than NH listeners. On average, the scores of HI listeners were relatively well accounted for by those of NH listeners tested with stimuli spectrally-shaped to match the frequency-dependent reduction in audibility of individual HI listeners. However, the scores of HI listeners were not significantly correlated with pure-tone audiometric thresholds and age.

Conclusions: These results indicate that the ability to discriminate natural soundscapes associated with changes in habitat, season and period of the day is disrupted but it is not abolished. The deficits of the HI listeners are partly accounted for by reduced audibility. Supra-threshold auditory deficits and individual listening strategies may also explain differences between NH and HI listeners.

感觉神经性听力损失改变了自然声景的听觉辨别能力。
目的:在15名患有双侧、轻度至重度感音神经性听力损失的听障(HI)听众和15名正常听力(NH)对照中,测量了在温带陆地生物群落中记录的自然声景的辨别能力。设计:使用三区间奇异性范式和恒定刺激方法测量声景辨别力。在每次试验中,在60或80的标称SPL下,对一天中不同栖息地、季节和时段的2秒记录序列进行立体呈现 结果:两组的辨别得分均高于偶然水平,但HI的辨别得分低于NH。平均而言,用频谱形状的刺激测试的NH听众的分数相对较好地解释了HI听众的分数,以匹配单个HI听众可听性的频率依赖性降低。然而,HI听众的得分与纯音听力阈值和年龄没有显著相关性。结论:这些结果表明,辨别与栖息地、季节和一天中的时间变化相关的自然声景的能力被破坏了,但并没有被废除。HI听众的不足部分是由于可听性降低造成的。阈上听觉缺陷和个体听力策略也可以解释NH和HI听众之间的差异。
