WebAmplitude is also the y-axis of the vibration time waveform and spectrum; it helps define the severity of the vibration. Amplitude Distribution a representation of time-varying noise indicating the percentage of time that the noise level is … WebWhen these high amplitude vibrations impinge upon the eardrum, they produce a very forceful displacement of the eardrum from its rest position. This high intensity sound wave causes a large vibration of the eardrum and subsequently a large and forceful vibration of the bones of the middle ear.
