Ecological momentary assessment (EMA) outcome measures can relate people's subjective auditory experience to their objective acoustical reality. While highly realistic, EMA data often contain considerable variability, such that it can be difficult to interpret the results with respect to differences in people's hearing ability. To address this challenge, a method for "guided" EMA is proposed and evaluated. Accompanied and instructed by a guide, normal-hearing participants carried out specific passive and active listening tasks inside a real-world public lunch scenario and answered EMA questionnaires related to aspects of spatial hearing, listening ability, quality, and effort. In situ speech and background noise levels were tracked, allowing the guided EMA task to be repeated inside two acoustically matched, loudspeaker-based laboratory environments: a 64-channel virtual sound environment (VSE) and a three-channel audiology clinic setup. Results showed that guided EMA provided consistent passive listening assessments across participants and conditions. During active listening, the clinic setup was found to be less challenging than the real-world and the VSE conditions. The proposed guided EMA approach may provide more focused real-world assessments and can be applied in realistic laboratory settings to aid the development of ecologically valid hearing testing.
生态瞬时评估（EMA）的结果可以将人们的主观听觉体验与客观声学现实联系起来。虽然 EMA 数据非常逼真，但通常包含相当大的可变性，因此很难根据人们的听力能力差异来解释结果。为了解决这一挑战，提出并评估了一种“引导”EMA 的方法。在一位指导者的陪同和指导下，正常听力的参与者在现实世界的公共午餐场景中进行了特定的被动和主动聆听任务，并回答了与空间听觉、听力能力、质量和努力相关的 EMA 问卷。原位语音和背景噪声水平被跟踪，使引导 EMA 任务可以在两个声学匹配的基于扬声器的实验室环境中重复进行：一个 64 通道虚拟声音环境（VSE）和一个三通道听力学诊所设置。结果表明，引导 EMA 在参与者和条件之间提供了一致的被动聆听评估。在主动聆听期间，发现诊所设置比现实世界和 VSE 条件更具挑战性。所提出的引导 EMA 方法可以提供更集中的现实世界评估，并可以在现实实验室环境中应用，以帮助开发具有生态有效性的听力测试。
