Binaural hearing is important for hearing target signals against competing ones, and for spatial hearing.
Survey of results using the Speech, Spatial and Qualities of Hearing scale (SSQ), a measure emphasizing contexts that rely on binaural hearing ability. Results show that self-rating can identify binaural hearing influences and benefits. RESEARCH DESIGNS: Retrospective design compared fitting with one versus two hearing aids. Prospective design compared one versus two cochlear implants. Brief descriptions are made of studies using other comparative designs.
There were 69 new adult-age clients of an audiology clinic with unilateral hearing aid fittings, 34 with bilateral (and n = 63 in a pre-aided sample); there were 14 people with one cochlear implant (CI), 18 with two; in both CI groups, age ranged from 20 to 90 yr.
The data are scores on the 49 items comprising the SSQ, grouped into 10 "pragmatic" subscales, analyzed using t-tests and ANOVA.
Two aids offer advantage for challenging conditions (e.g., multistream signal monitoring), for dynamic spatial hearing, and in reducing listening effort. These outcomes are observable, though less distinctly, in one versus two implants. Overall advantage of two implants is very clear in a 20-59-yr-old cohort of patients. Recent application and development of the SSQ indicates sensitivity to subtle differences in abilities.
Self-report data are valuable in revealing the everyday listening domains in which improvement in binaural hearing function provides beneficial outcomes.
双耳听力对于在竞争性声音中听清目标信号以及空间听觉很重要。
使用言语、空间和听力质量量表（SSQ）对结果进行调查，该量表强调依赖双耳听力能力的情境。结果表明，自我评估能够识别双耳听力的影响和益处。研究设计：回顾性设计比较了单耳与双耳佩戴助听器的情况。前瞻性设计比较了单侧与双侧人工耳蜗植入的情况。还简要描述了使用其他比较设计的研究。
一家听力诊所的69名新成年客户单侧佩戴助听器，34名双侧佩戴助听器（预佩戴样本中有63名）；14人植入了单侧人工耳蜗（CI），18人植入了双侧；在两个CI组中，年龄范围为20至90岁。
数据是SSQ包含的49个项目的得分，分为10个“实用”子量表，使用t检验和方差分析进行分析。
双耳佩戴助听器在具有挑战性的条件下（例如多流信号监测）、动态空间听觉以及减少听力努力方面具有优势。在单侧与双侧人工耳蜗植入的比较中也可观察到这些结果，尽管不太明显。在20至59岁的患者队列中，双侧人工耳蜗植入的总体优势非常明显。SSQ的最新应用和发展表明其对能力细微差异具有敏感性。
自我报告数据对于揭示双耳听力功能改善能带来有益结果的日常听力领域很有价值。
