Additionally, the ultrasonic speaker is implemented with an impedance matching element or optimized for matching the response within a user's ear canal.Brian Alan KappusElwood Grant Norris
Thus the stapes became an important element in an impedance matching system, coupling airborne sound waves to the receptor system of the inner ear. 故此鐙骨是阻抗匹配系統中的一個重要元素,將空氣傳播的聲波,帶到內耳的接收器中。 WikiMatrix The impedance matching method and impedance matching syste...

It is concluded that the acoustic impedance matching criteria are of great value in layer thickness measurement using ultrasonic interferometry. 针对超声干涉法测量薄层厚度的原理,讨论了薄层及与其相邻介质声阻抗匹配分别满足界面声压反射系数|R1|<1/2或|R1|>1/2时回波信号的选取原则,并以薄层声压反射系数谱为...
Additionally, the ultrasonic speaker may be implemented with an impedance matching element or optimized for matching the response within a user's ear canal, and the ultrasonic audio transducer system may include The ultrasonic audio headphone system can further include a frequency mismatched microphone ...

Yes, the difference inimpedancewould be fairly large. EXTRALIFE – By Scott Johnson - These guys are brilliant…2008 One of the problems the middle ear has to overcome is the mismatch inimpedancebetween air and the cochlea, but impedance matching by the middle ear results in only a 30 dB ...
in the recording industry to this day. One consequence of this direct borrowing of technology was that early broadcast and recording studios also employed the 600Ω matched-impedance principle for almost everything — tape machine outputs, console inputs, and so on. However, the idea of matching...
