电视及无线电的声音广播质量在很大程度上取决于音响工作人员的业务水平。其中最重要的因素之一就是要有极好的听觉。为了检查听觉上的缺陷,首先要进行听力测量。这种测量在医学单位是按鉴定过的方法进行的。但是对于评价一个音响工作者的听觉,这种方法是不够的,还需要用客观的方法,以评价音乐听觉的精细程度和在高声强负荷情况下的听觉的稳定性,从而选出最好的音响导演的候选人。听觉差阈的测量方法西绍尔于1910年首先研究出了这种方法。它籍助一组音叉来检查被测者能清晰分辨音调高度的最小间隔,确定了在较好的情况下这个间隔等于1～3音分(1音分=0.01
The quality of the sound of television and radio broadcasts depends very much on the sound quality of the audio staff. One of the most important factors is to have excellent hearing. In order to check the auditory defects, we must first make audiometry. This measurement is carried out in a medical unit according to the method identified. However, this method is not sufficient for evaluating the hearing of an acoustic worker. It is also necessary to select an objective method to evaluate the fineness of the auditory sense of hearing and the auditory stability under loud and intense loading conditions Audio director’s candidate. Measurement method of auditory threshold Thierseurs first developed this method in 1910. It uses a set of tuning forks to examine the minimum interval at which the subject can clearly discern the pitch and determines that in the better case this interval is equal to 1 to 3 points (1 point = 0.01
