BENCHMARK: Audio application notes – Speaker Sensitivity and Amplifier Power

John Siau writes:

Speaker sensitivity is a measure of how loud a speaker will play at a given input power or at a given input voltage. Sensitivity is normally measured with a 1 watt power input or a 2.83 Vrms voltage input. The acoustic output is normally measured in an anechoic space at a distance of 1 meter from the speaker. At 8-Ohms, 1 watt and 2.83 Vrms are equivalent. The following chart shows typical sensitivity ranges:
