目的：比较言语呈现水平对听力正常和听力受损的听众对噪音接受的影响。方法：参与者为听力正常的听众（n = 24）和听力受损的听众（n = 46）。听力正常的人进行匹配的常规可接受噪声水平（ANL）。然后在8个固定的语音呈现水平（40、45、50、55、60、65、70和75 dB HL）下测量ANL以确定全局ANIL（即，在语音呈现水平上平均的ANL）或ANL生长（即，结果：使用整体ANL评估了言语呈现水平对噪声接受的影响。ANL的增长。结果表明，全球ANIL和ANL增长没有显着不同的听力正常和受损的听众，无论是ANL措施与纯音平均听力受损的听众。此外，传统的ANLs显着相关的全球ANLs和ANL的增长为所有listeners.Conclusion：这些结果表明，语音呈现水平对噪声的接受效果是不相关的听力灵敏度。这些结果进一步表明，听众的常规ANL与他或她的全球ANL和ANIL增长有关。
Purpose: To compare the effects of speech presentation level on acceptance of noise in listeners with normal and impaired hearing.Method: Participants were listeners with normal (n = 24) and impaired (n = 46). hearing who were matched for conventional acceptable noise level (ANL). ANL was then measured at 8 fixed speech presentation levels (40, 45, 50, 55, 60, 65, 70, and 75 dB HL) to determine if global ANIL (i.e., ANL averaged across speech presentation levels) or ANL growth (i.e., the slope of the ANL function) varied between groups.Results: The effects of speech presentation level on acceptance of noise were evaluated using global ANLs. and ANL growth. Results showed global ANIL and ANL growth were not significantly different for listeners with normal and impaired hearing, and neither ANL measure was related to pure-tone average for listeners with impaired hearing. Additionally, conventional ANLs were significantly correlated with both global ANLs and ANL growth for all listeners.Conclusion: These results indicate that the effects of speech presentation level on acceptance of noise are not related to hearing sensitivity. These results further indicate that a listener's conventional ANL was related to his or her global ANL and ANIL growth.
