瞬态响应对耳机清晰度的影响

摘要

利用不同的耳机均衡方法对耳机到鼓膜的传递函数进行均衡,以探讨瞬态响应对耳机清晰度的影响.主客观实验结果表明,瞬态响应衰减越快,耳机重放声源的清晰度提升越显著.由于耳机与助听器发声单元类似,对耳机清晰度的研究也对如何提高助听器言语或音乐的清晰度起指导作用.%To investigate the effects of transient response on headphone articulation,different headphone equalization methods are used to equalize the headphone-to-eardrum transfers function.The objective and subjective experiments suggest that the faster the transient response attenuates,the greater the headphone articulation will be.As the acoustic transmission units in the hearing aids are similar to that in headphones,this investigation can guide.The improvement speech or music articulation in hearing aids.
