Abstract

A previous report [Margolis and Stiepan (2012). "Acoustic method for calibration of audiometric bone vibrators," J. Acoust. Soc. Am. 131, 1221-1225] described a reliable, inexpensive, acoustic method for calibration of audiometric bone vibrators. As a follow up to that report harmonic distortion measurements were made with the standard electromechanical method and the acoustic method using five Radioear B71 vibrators and one Radioear B81 prototype vibrator. Lower distortion was seen for measurements made with the acoustic method compared to the electromechanical method and for the Radioear B81 vibrator compared to the Radioear B71 vibrator.
