clapometerとは 意味・読み方・使い方

A clap-o-meter, clapometer or applause meter is a measurement instrument that purports to measure and display the volume of clapping or applause made by a studio audience or an audience at some other event. It is used to decide the result of competitions based on the popularity of the contestants, or at least give an indication of their popularity. It may or may not be based on an actual sound level meter. Clap-o-meters were a popular element in talent shows and television game shows in the 1950s and 1960s, most notably Opportunity Knocks, but have been since been supplanted by other, more sophisticated, methods of measuring audience response.
