The Impact of Individual Head-Related Transfer Function Augmentation on Spatial Release from Masking

Anonymised Behavioural Data from Speech-on-Speech Spatial Release from Masking Tests This repository contains anonymised behavioural data collected for the study: “The Impact of Individual Head-Related Transfer Function Augmentation on Spatial Release from Masking.” Marggraf-Turley, N., Pontoppidan, N., Picinali, L. (2025) Data Description The dataset includes trial-by-trial responses from spatial release from masking (SRM) experiments. In these tests, participants were presented with spatialised speech stimuli based on their individual head-related transfer functions (HRTFs) and two augmented HRTF conditions involving interaural magnification. Stimuli were derived from the Coordinate Response Measure (CRM) corpus and followed the structure: “Ready [Call Sign], go to [Colour] [Number] now.” Each sentence was defined by a combination of: - Call Signs: Arrow, Baron, Charlie, Eagle, Hopper, Laker, Ringo, Tiger - Colours: Blue, Red, Green, White - Numbers: 1–8 Each trial specifies the target and masker sentence configurations based on these values. Usage Notes - Stimulus Reconstruction: Specific target and masker sentences can be reconstructed from the call sign, colour, and number combinations listed in each trial record. - Data Anonymisation: All participant identifiers have been removed in accordance with ethical guidelines. - Experimental Context: Participants completed trials across multiple masker separations (co-located and spatially separated maskers) and HRTF types (individual and augmented).

(2025)。 ## 数据集说明 本数据集涵盖掩蔽空间释放（Spatial Release from Masking, SRM）实验的逐试次反应数据。实验中，参与者接收基于其个体头相关传输函数（Head-Related Transfer Function, HRTF）以及两种涉及耳间放大的增强型HRTF条件生成的空间化言语刺激。 刺激素材源自坐标响应度量（Coordinate Response Measure, CRM）语料库，语句结构统一为："Ready [呼号], go to [颜色] [数字] now." 每一句语句由以下要素组合定义： - 呼号：Arrow（箭头）、Baron（男爵）、Charlie（查理）、Eagle（鹰）、Hopper（跳跃者）、Laker（湖光）、Ringo（林戈）、Tiger（老虎） - 颜色：Blue（蓝色）、Red（红色）、Green（绿色）、White（白色） - 数字：1至8 每一试次均基于上述要素明确目标语句与掩蔽语句的配置。 ## 使用须知 - 刺激重构：可根据每一试次记录中列出的呼号、颜色与数字组合，还原出对应的目标与掩蔽语句。 - 数据匿名化：所有参与者标识均已依据伦理准则移除。 - 实验背景：参与者完成了多组不同掩蔽声间距（共置与空间分离掩蔽声）以及不同HRTF类型（个体型与增强型）的试次。 若需了解实验方法、信号处理细节（包括耳间相位差（Interaural Phase Difference, IPD）/耳间声级差（Interaural Level Difference, ILD）与耳间时间差（Interaural Time Difference, ITD）/ILD增强算法）以及模型评估结果，请参阅完整论文手稿。
