Impedance matching — In electronics, impedance matching is the practice of designing the input impedance of an electrical load (or the output impedance of its corresponding signal source) to maximize the power transfer and/or minimize reflections from the load.… … Wikipedia
impedance — 1. Total opposition to flow. In electricity, when flow is steady, i. is simply the resistance, e.g., the driving pressure per unit flow; when flow is changing, i. also includes the factors that oppose changes in flow. Thus, deviations of i., from … Medical dictionary
Acoustic reflex — The acoustic reflex (stapedius reflex, attenuation reflex, or auditory reflex) is an involuntary muscle contraction that occurs in the middle ear of mammals in response to high intensity sound stimuli.When presented with a high intensity sound… … Wikipedia
