技术英国研究人员日前开发出了一种声音分离装置,该装置可以帮助有听力障碍的人选择要听的声音并降低背景噪音,从而听懂更多的语句。目前市场上的感应回路系统和助听器虽然可以用来提高周围声音的音量,但不能瞄准目标并有效地放大特定声音。英国皇家聋人协会(RNID)的40名会员已对该装置的原型机进行了测试。志愿者用他们的助听器(设置到T档)收听通过一个回路系统播放的一系列录音。每段录音都有一系列的押韵字词,志愿者要在不同程度的背景噪音下佩戴与不佩戴该智能扩音器来辨别这些词。测试结果显示,参与者在中等程度的背景噪音下佩戴该智能扩音器多听懂了差不多50%的言语。
Technology British researchers have recently developed a sound separation device that can help hearing impaired people choose to listen to the sound and reduce the background noise to understand more sentences. While currently available inductive loop systems and hearing aids can be used to increase the volume of surrounding sounds, they can not aim at a target and effectively amplify a particular sound. Forty members of the Royal Deaf Association (RNID) have tested the prototype of the unit. Volunteers use their hearing aids (set to T-range) to listen to a series of recordings played through a loop system. Each recording has a series of rhyming words, volunteers to be with different levels of background noise wear and do not wear the smart speaker to identify these words. The test results showed that participants wearing the smart loudspeaker with a medium level of background noise understood almost 50% of the speech.
