关门声入射角度对人工头双耳测试结果的影响

Influence of Incidence Angles of Door Closure Sound to Binaural Test Results of Artificial Head

关门声在不同入射角度时,人工头双耳所测的声压级、响度和尖锐度等关门声品质客观评价参数会产生变化。借助响度总体感知模型,分析讨论响度和尖锐度总体感知随关门声入射角度的变化。结果表明,随着入射角度不断增大,单耳响度和尖锐度变化较大,总体感知则变化较小。

The binaural variation of the attributes, such as SPL, loudness and sharpness, which quantify the sound quality of door closure at different incidence angles, were changed. Based on the overall loudness perception model in dichotic conditions, the overall perception of loudness and sharpness was analyzed. The results show that the loudness and sharpness of each ear had a big change with the increase of incidence angel, while the overall perception had little change.
