活动场所的语言清晰度和鸡尾酒会效应

本文讨论人们活动场所的语言清晰度，鸡尾酒会效应和它对语言清晰度的影响，对会议厅，剧院，教室，侯机大厅，侯车厅，体育馆，溜冰场等处的测量和清晰度试验，建立了主观评价和清晰度得分关系并给出一些这类场所不引起鸡尾酒会效应的允噪声级阈值，最后讨论了鸡尾酒会效应的计算机模型。

Speech intellingibility and the cocktail-party effect in activity areas

In this paper are discussed the assessment of the speech intelligibility and the phenomenon of cocktail-party effect in activity areas, referring to halls accomodating noisy speech activities. Through measurements in many areas like conference halls, theaters, meeting rooms, churches, we establish a correspondance between the subjective assessment of speach listening quality and intelligibility scores as percentages. Various allowed thresholds of noise level in order to prevent the cocktail-party effect are suggested and a computer model for the effect is established.
