impedance
noun
im·ped·ance im-ˈpē-dᵊn(t)s 
a
: the apparent opposition in an electrical circuit to the flow of an alternating current that is analogous to the actual electrical resistance to a direct current and that is the ratio of effective electromotive force to the effective current
b
: the ratio of the pressure to the volume displacement at a given surface in a sound-transmitting medium
Example Sentences
Recent Examples on the Web And finally, this MacBook has more ports again, including an HDMI port, three USB-C ports with Thunderbolt 4, an SD card slot, and a high-impedance headphone jack. 
Medea Giordano, WIRED, 9 Sep. 2022 The audio jack supports high-impedance headphones, which is nice. Ewan Spence, Forbes, 10 June 2022 The AK HC2 has an analog amplifier powerful enough to drive high-impedance headphones and the option of a 4.4mm balanced output offers lower noise, higher output and clearer channel separation. Mark Sparrow, Forbes, 13 May 2022 The scale tracks this information using bioelectrical impedance technology, which basically sends a low electrical current through your body, then measuring the resistance of tissue in the body to the current. Maren Estrada, BGR, 27 Apr. 2022 The easy-to-drive ADVAR are designed specifically to pair well with a wide selection of audio devices thanks to their high sensitivity and low impedance. Mark Sparrow, Forbes, 12 Apr. 2022 Special care has been taken to marry a low-density nitrile surround to the cone, to match its impedance and reduce reflections from the cone edge. Mark Sparrow, Forbes, 17 Mar. 2022 Body fat analyzers: There are affordable, easy-to-use body fat analyzers out there, including skinfold calipers and bioelectrical impedance analyzers, which use low-level electrical currents to measure your body fat percentage. Suzie Glassman, Health.com, 31 Jan. 2022 The HybridDigital nCore design has a wide bandwidth, flat frequency response, clean clipping behavior with instant recovery, high current capability, and stability when used with demanding low-impedance speakers.
