摘要

由于大规模集成电路(VLSI)的技术进步，高速数字信号处理(DSP)芯片变得足够快，可以在足够小的可穿戴设备上实时实现助听器算法。本文研制了一种基于专用DSP芯片的体戴式数字助听器(DHA)。在Win95操作系统的支持下，开发了相应的PC机软件。拟合协议是基于应用于八个频段的NAL-R程序，但它旨在支持曲线拟合，以应对听障听众的非线性感知。关于语音清晰度和感知质量的初步主观测试显示，新的DHA可能对助听器用户有益。

A digital hearing aid with 8-band curvilinear loudness fitting

Owing to technological advances in very large-scale integrated (VLSI) circuits, high-speed digital signal processing (DSP) chips become fast enough to allow for real-time implementation of hearing aid algorithms in units small enough to be wearable. In this paper, a body-worn type digital hearing aid (DHA) based on a dedicated DSP chip is developed. A fitting software running on a PC supported by the Win95 OS is also developed. The fitting protocol is based on the NAL-R procedure applied to eight frequency bands, but it is designed to support a curvilinear fitting to cope with the nonlinear perception of hearing-impaired listeners. Preliminary subjective tests regarding the speech intelligibility and perceived quality revealed that the new DHA could be of benefit to hearing aid users.
