The goals of this investigation were to determine whether hearing aid benefit improved significantly over the first 10 weeks of hearing aid use and whether time-related changes in benefit (if any) were affected by the type of benefit measurement (i.e., objective or subjective). A total of 17 hearing-impaired subjects participated, with different subjects completing different phases of the study. Benefit was measured soon after the hearing aid fitting and again after 10 weeks of adjustment to hearing aid use. Objective benefit data were determined using the Connected Speech Test. No significant changes in objective benefit were noted in noisy or reverberant listening environments when visual cues were available. However, in a low-noise setting and in a noisy setting without visual cues, improvements in objective benefit were seen over time. Subjective benefit data were derived from responses to the Profile of Hearing Aid Benefit. These data indicated significant benefit improvement over time in all five types of daily life situations assessed, although the improvement was small in reverberant and noisy environments. Significant, but modest, correlations were found between objective and subjective data for low-noise and reverberant listening environments. Comparison of experienced and novice hearing aid wearers suggested that although experienced wearers obtain more benefit than novice wearers, they evidence similar time-related changes in benefit during the first 10 weeks of new hearing aid use.
本研究的目的是确定在使用助听器的前10周内，助听器的助听效果是否有显著改善，以及助听效果随时间的变化（如有）是否受助听效果测量类型（即客观或主观）的影响。共有17名听力受损受试者参与，不同受试者完成研究的不同阶段。在助听器验配后不久以及在适应使用助听器10周后再次测量助听效果。使用连贯言语测试确定客观助听效果数据。当有视觉线索时，在嘈杂或混响的聆听环境中未发现客观助听效果有显著变化。然而，在低噪声环境和无视觉线索的嘈杂环境中，随着时间的推移客观助听效果有所改善。主观助听效果数据来自对《助听器助听效果概况》的回答。这些数据表明，在评估的所有五种日常生活情境中，助听效果随时间有显著改善，尽管在混响和嘈杂环境中的改善很小。在低噪声和混响聆听环境中，客观数据与主观数据之间存在显著但适度的相关性。对有经验和无经验的助听器佩戴者的比较表明，尽管有经验的佩戴者比无经验的佩戴者获得更多益处，但在新使用助听器的前10周内，他们在助听效果方面的时间相关变化相似。
