摘　　要：实验采用极限法,测量不同频率声音的听觉阈限,进而研究纯音听觉阈限与不同频率的关系。实验表明:对同一被试,绝对听觉阈限与不同频率的刺激有关,且呈现"U"字的相关;听觉感受性最高的频率在2000HZ到4000HZ之间;深吸气对绝对听觉阈限有一定的干扰;听觉阈限的测量中存在着"回视"现象。This experiment adoption limit method, measure the auditory threshold of the different frequency voice, then study the relation between the pure sound auditory threshold and different frequency. Experiment indicate： To same the subject, the absolute auditory threshold has something to do with the different frequency stimulus, and present ＂U＂ correlation; The hearing impressibility maximal frequency is between the 2000 -4000 HZ; Deeply inhale to have certain interference to the absolute auditory threshold ; It exist ＂ Back - skipping ＂ phenomenon in the measure the auditory threshold.
