摘要
根据2003年颁布的ISO226对原版本作了显著修正的现象,进行了针对中国人群的60phon～80phon等响曲线的初步研究,旨在检验中国人群的等响曲线与新颁布的ISO标准的符合程度。研究结果表明,中国人群的60phon～80phon等响曲线的结果与新版本ISO标准仍然存在一定的差异,而与日本人群的等响曲线相对接近。根据初步研究结果,提出了等响曲线存在地域性人群差异的概念以及需要对各地域人群的等响感知特征进行区别研究的思想。
Taking into account the significant differences between the recently revised equal-loudness level contours （ELLCs） and that specified in the former version of ISO 226 standard, a preliminary investigation of Chinese speakers＇ ELLCs from 60phon to 80phon was carried out. The purpose of the study is to verify the conformity of Chinese speakers＇ ELLCs with the new ISO standard. Our results show that remarkable differences still exist between China and ISO, and ELLCs of Chinese speakers are closer to that of Japanese. From the initial results, it may be concluded that ELLCs have regional difference. Therefore it is necessary to study the effects indi＇ vidually on a regional basis.
