单独控制的降噪装置为学龄儿童提供更好的教室声环境发表时间:2021-09-03 15:36 最近发表的一项基于模拟的研究证明了单独控制的降噪装置(ICND:Individually Controlled Noise-reducing Device)对改善教室声学质量的效果。作为后续研究,本研究旨在开发一个真正的ICND,并用其目标用户 — — 小学生对其进行测试。在这项研究中开发的原型看起来像一个挂在桌子上的天篷,是经过挑选和原型化的。它有两种模式,即打开和关闭,可通过遥控器轻松更改。有了这个装置,学龄儿童可以自己控制当地的声环境。超过200名小学生被邀请在SenseLab的声学室中测试该设备的两个原型。结果显示,83%的孩子喜欢这个设备,61%的孩子想在自己的教室里使用它。然而,由于这是一个原型,仍有改进的余地。根据孩子们的反馈,总结了未来修改的几点建议。 ![]()
