目的：评估在声场中鸡尾酒会环境中的听力困难，以更好地展示患者在噪声中的听力困难，并与对照组相比，研究时间和方向线索对噪声中听力困难患者言语可懂度的影响。设计：本研究检查并分析了16名无听力困难主诉的对照受试者和16名在东北大学附属医院耳鼻咽喉头颈外科门诊就诊的听力困难患者，特别是在背景拥挤的情况下，尽管在常规听力图和言语听力测定中具有相对良好的听力。使用位于受试者前方的五个扬声器，从前方向左和向右分别为30和60，目标声音的单词清晰度（女性说话者）从一个扬声器中随机顺序呈现四个干扰声音（男性说话者）在以下提示条件下进行评估：（1）“没有额外的时间/方向提示（2）“固定时间线索，无方向性线索”（就在单词呈现之前，以500 ms的间隔从五个扬声器呈现白色噪声突发[提示声音]）;（3）“方向性+可变时间提示”（从扬声器呈现提示声音，其中下一个目标词将被呈现，在提示声音和词呈现之间具有500、1000、1500或2000 ms的可变刺激间间隔[ISI]）;（4）“方向性+固定时间线索”（提示声音从扬声器呈现，其中下一个目标词将以500 ms的固定ISI呈现）。（1）与对照组相比，听力障碍患者在干扰物下的单词可懂度显著下降，虽然使用耳机系统的噪声测试中的临床言语在两组之间没有显示出任何显著差异;（2）在干扰物作用下，提前提示方向性信息能显著提高听力障碍患者的词汇可懂度;（3）在大多数提示条件下，听力障碍患者的单词可懂度个体差异与其双耳分听能力显著相关，双耳分听能力是评价听觉选择性注意能力的指标之一。本研究的结果表明，有用的演讲理解在鸡尾酒会的情况下，在听力困难的患者，以及在鸡尾酒会的情况下，空间上的听力困难的程度进行评估的重要性的方向性线索的介绍。
Objectives:To evaluate the listening difficulty in a cocktail party environment in the sound field in order to better demonstrate patients’ difficulties listening in noise, and to examine temporal and directional cue effects on the speech intelligibility in patients with listening difficulties in noise in comparison with control subjects.Design:This study examined and analyzed 16 control subjects without any complaints of listening difficulties and 16 patients who had visited the outpatient clinic of the Department of Otolaryngology-Head and Neck Surgery, Tohoku University Hospital, with complaints of listening difficulties, especially in background crowded conditions, despite having relatively good hearing on routine audiograms and speech audiometry. Using five loudspeakers located in front of the subject and at 30 and 60 to the left and right from the front, word intelligibility for the target voice (female talker) presented from one of the loudspeakers in random order with four distractor voices (male talker) was assessed under the following cue conditions:(1)“no additional temporal/directional cue (only talker sex as a cue)”;(2)“fixed temporal cue without directional cue”(white noise bursts [cue sounds] were presented from the five loudspeakers just before word presentation at 500-ms intervals);(3)“directional+ variable temporal cues”[cue sounds were presented from the loudspeaker where the next target word would be presented with a variable inter-stimulus interval [ISI] of 500, 1000, 1500, or 2000 ms between the cue sound and word presentation); and (4)“directional+ fixed temporal cues”(cue sounds were presented from the loudspeaker where the next target word would be presented with a fixed ISI of 500 ms).Results:The results indicated the following:(1) word intelligibility under distractors was significantly deteriorated in patients with listening difficulties compared with control subjects, although the clinical speech in noise test using the headphone system did not show any significant differences between the two groups;(2) word intelligibility under distractors for patients with listening difficulties was significantly improved with directional cues presented in advance; and (3) under most cue conditions, individual differences in word intelligibility among patients with listening difficulties were significantly correlated with their dichotic listening ability, which is one of the indicators used to assess auditory selective attention ability.Conclusions:The results of this study indicate the usefulness of the presentation of directional cues for speech comprehension in the cocktail party situation in patients with listening difficulties, as well as the importance of evaluating the degree of listening difficulties spatially in the cocktail party situation.
