这项贡献描述了通过使用双耳耳机合成改变或塑造记录的双耳室内脉冲响应的两个基于能量的参数对听觉事件的感知方向、距离和外部化的影响。提出并评价了非个性化双耳耳机复制中距离知觉的受控修正。该算法系统地改变基于时间和能量的脉冲响应的距离相关特性。新的双耳房间脉冲响应(BRIR)由基于初始时间延迟间隔的能量自适应来形成。听力测试表明，测量的BRIR和新合成的BRIR导致相似的距离知觉。在第二个实验中，直接混响比(DRR)被改变，直到测试者感觉到合成的房间和收听室之间的一致性。所有测试还考察了合成室和听音室之间的一致性和差异性的知觉效应。
This contribution describes effects on perceived direction, distance, and externalization of auditory events by changing or shaping two energy based parameters of recorded binaural room impulse responses using a binaural headphone synthesis. A controlled modification of the distance perception in non-individualized binaural headphone reproduction is presented and evaluated. The algorithms change systematically time and energy based distance-dependent properties of impulse responses. The new binaural room impulse responses (BRIRs) are shaped by an energy adaption based on the initial time delay gap. Listening tests show that measured BRIRs and the newly synthesized BRIRs cause similar distance perception. In a second experiment the direct-to-reverberant-ratio (DRR) is changed until the test person perceived congruence between the synthesized and the listening room. All of the presented tests also investigate perceptual effects of congruence and divergence between the synthesized room and the listening room.
