Abstract

Describes the method for measuring the characteristics at load (internal mechanical vibration loss, electroacoustic conversion efficiency, etc.) of a bolt-clamped Langevin vibrator of which the resonance frequency is 10 kHz to 100 kHz (hereafter referred to as "vibrator") by the wattmeter method and calculating them.
