Clinical and research concerns with vibratory stimulation: a review and pilot study of common stimulation devices
The parameters of vibrators used for sexual stimulation in laboratory settings and therapeutic contexts are usually unknown. The unidentified range of vibrator characteristics commonly used for sexual stimulation would help identify
appropriate vibrator for different purposes and clients. Seven vibrators used for sexual stimulation were tested using a piezoelectric accelerometer mounted on their housing to quantify frequency, displacement, and acceleration of each.
Vibratory frequency ranged from 43 to 148 Hz
