Significance of Amplitude
Amplitude, according to Science, is defined as the height of the EEG waveform, measured as a bilateral EEG amplitude of at least 1.5 cm from peak to trough. It serves as a measure of the strength of auditory brainstem response, recorded in microvolts (μV) to reflect neural activity. Additionally, amplitude is a key parameter in Vestibular Evoked Myogenic Potentials (VEMPs), indicating the magnitude of the response and aiding in the diagnosis of peripheral vestibular lesions.

The concept of Amplitude in scientific sources
Amplitude is defined as the height of EEG waveforms, measured bilaterally, as well as a key parameter in VEMPs for diagnosing vestibular lesions and the strength of the auditory brainstem response, assessed in microvolts.

(1) This is a measure of the height of a wave, expressed in millimeters, and is a key factor in understanding the effects of vibration on the body.[1] (2) Amplitude is a VEMPs parameter, which refers to the magnitude of the response, and is mainly used to diagnose peripheral vestibular lesions.[2] (3) This is a measure of the strength of the auditory brainstem response, which can be measured in microvolts (μV), indicating the neural activity.[3] (4) Amplitude refers to the height of the EEG waveform, and it is measured as a bilateral EEG amplitude of at least 1.5 cm in height from the peak to the trough.[4]
