One of the problems the middle ear has to overcome is the mismatch in impedance between air and the cochlea, but impedance matching by the middle ear results in only a 30 dB increase in sound energy transmitted to the inner ear. A Decade Spanning Single Exchange 2008 Guts: One of the pro...
The larger aperture controlled the resonance frequency and the smaller one allowed the resonance tone to be heard when placed to the ear. (The reader might like to consider how connection to the ear canal alters the resonance frequency.) The archetypal Helmholtz resonator, consisting of a neck ...
Headphones, like loudspeakers, also present a load impedance to the driving amplifier. However, there are three main classes of headphone design — and I'm talking just about impedances here, not the arguments over closed-backed, open-backed, or in-ear designs. The impedance of a headphone...
“The single most important technological factor to consider when looking for a headphoneamplifierthat works well with your ear phones is impedance matching.”–RHA Audio We will look at the rules around finding that perfect match in some detail below. For now, it is enough to understand that...

Another object of the present invention is to provide the impedance matching type electrical connector described above, wherein each male conductor further has plate portions, and first and second ear portions bent on both ends of the male conductor in a direction taken along a width of the male...
An acoustic horn has an acoustic impedance matched with impedances of an ear and a driver. The acoustic horn can be used in an electroacoustic transducer including the driver, and t
