TACTILE AIDS AND DIRECTIONAL MICROPHONES

可穿戴触觉设备作为语音阅读辅助设备的用途包括 比助听器更快地受到背景噪音的影响。 然而，在试图处理这个问题时，必须牢记 这样的触觉设备也被用作简单的声音识别辅助设备 对于失聪人群，所以采用了减少朗读的方法 困难必须考虑到这类装置的其他使用方式。 定向传声器降低噪声干扰的能力 语音朗读和小型语音麦克风的制作技术 在第一阶段部分已经演示了抗机箱噪音的封装 在这项研究中。在这项后续研究中描述的工作重点是 通过将定向麦克风与触觉用户相结合来满足不同需求 一种自适应电子网络，自动使麦克风 当没有响亮的语音信号时，作为全方位单元运行 沿着接收的主轴。这部分研究的主要目标是 是构建这样一个自适应麦克风系统的两个版本，一个 穿着身子，戴着一个头，并与有经验的人进行现场评估 触觉辅助用户。这种自适应定向传声器系统 将提高触觉辅助系统、人工耳蜗系统的效用 可能还有助听器。如果工作成功， 听觉工程学要么制造出这样的自适应 麦克风系统或与另一个人签订许可协议 制造商必须这样做。

The utility of wearable tactile devices as speech reading aids are compromised by background noises even more rapidly than are hearing aids. However, in attempting to deal with this problem it must be kept in mind that such tactile devices are also used as simple sound awareness aids by the deaf population, so methods used to reduce the speech reading difficulty must take into account other use modalities of such devices. The ability of directional microphones to decrease noise interfering with speech reading and the technology for building such microphones in small case-noise resistant packages has been demonstrated in the Phase I portion of this study. The work describe in this follow-on study focuses on the different needs of tactile users by combining a directional microphone with an adaptive electronic network that automatically causes the microphone to operate as an omnidirectional unit when no loud speech signal is present along the main axis of reception. The major goal in this part of the study is to construct two versions of such an adaptive microphone system, one body worn and one head worn, and field evaluate them with experienced tactile aid users. This kind of an adaptive directional microphone system would enhance the utility of tactile aid systems, cochlear implant systems and probably hearing aids as well. In event the work is successful, Audiological Engineering would either manufacture such an adaptive microphone system or enter into a licensing agreement with another manufacturer to do so.
