Tapping the tuning fork, collecting acoustic waveform. It was found: tapping thetuning fork, fork small amplitude, small-amplitude waveform, then the soundemitted by the tuning fork is small; heavy knock amplitude tuning fork, fork is large, the amplitude of waveform is large, then the sound emitted by the tuning fork is also large. Description: loudness with tuning fork vibration amplituderelated. Amplitude, the greater the loudness; amplitude is smaller, the smaller theloudness.
