目的：绝大多数先前的研究表明，可接受的噪声水平（ANL）和纯音听阈之间没有关系，纯音听阈被报告为平均纯音听阈（纯音平均值）。本研究的目的是探讨（a）在个别频率和ANL和（B）的听力图和ANL.Method的斜率的测量听阈之间的关系：63丹麦成人助听器用户参加。评估纯音听力图和3个不同版本的ANL测试单耳在2个不同的sessions.Results：研究结果表明，低频听阈和听力图的斜率显着相关的所有版本的ANL。结论：可能以前的研究没有发现ANL和听阈之间的关系，因为使用了宽的4频纯-平均音调。这对我们理解ANL测试有影响。
Purpose: The vast majority of previous studies suggest that there is no relationship between the acceptable noise level (ANL) and pure-tone hearing thresholds reported as the average pure-tone hearing thresholds (pure-tone average). This study aims to explore (a) the relationship between hearing thresholds at individual frequencies and the ANL and (b) a measure of the slope of the audiogram and ANL.Method: Sixty-three Danish adult hearing aid users participated. Assessments were pure-tone audiogram and 3 different versions of the ANL test made monaurally at 2 different sessions.Results: The findings show that low-frequency hearing thresholds and the slope of the audiogram are significantly related to all versions of the ANL.Conclusion: It is possible that previous studies have failed to discover a relationship between ANL and hearing thresholds due to the use of the broad 4-frequency pure-tone average. This has implications for our understanding of the ANL test.
