摘要:
The reliability of two methods in detecting the acoustic null with the Zwislocki bridge using trained listeners was investigated. One method consisted of the subjects listening directly from the bridge with a stethoscopic headset. The other method consisted of the signal being amplified and then detected by an oscilloscope readout and listening combined. There were no significant differences between methods even though the subjects preferred the direct listening method.
