描述(改编自申请人摘要)。 该项目是开发一种高频入耳式扬声器和麦克风 用于灵敏度高达100 kHz的听觉研究。演讲者将是 能够在耦合环境中产生至少100 dBSPL，并具有平坦的 从1千赫到100千赫的频率响应。麦克风将会是 宽带，与扬声器的带宽匹配，并将有足够的带宽 灵敏度(5 mV/pa)和低噪声电平(&lt；10 dBSPL)，用于在 用于耳部信号和耳声发射的研究。演讲者 麦克风外壳的设计将使它们可以很容易地连接到 各种大小的实验动物的耳朵。扬声器和麦克风 将使用静电技术开发，该技术提供 需要较宽的带宽。 建议的商业应用： 用于研究应用的高频扬声器和麦克风。

Description (Adapted from applicant's Abstract). The project is to develop a high-frequency in-the-ear speaker and microphone for auditory research with sensitivities up to 100 kHz. The speaker will be able to produce at least 100 dB SPL in a coupled environment and feature a flat frequency response from 1 kHz to 100 kHz. The microphone will be wide-bandwidth, matching that of the speaker and will have sufficient sensitivity (5 mV/Pa) and low noise level (<10 dB SPL) for calibrating in the ear signals and for performing studies with otoacoustic emissions. The speaker and microphone housings will be designed so that they can be easily coupled to a wide range of ear sizes of experimental animals. The speaker and microphone will be developed with electrostatic technology that provides the wide-bandwidth required. PROPOSED COMMERCIAL APPLICATION: High frequency speaker and microphone for research applications.
