Something very bad happened in the class need some advice :)?

Wore brush's and frequency, A hum above or below human hearing. Pulsed by a electronic wave. Set the inner ears to vibrating. It is rare. But has happened. If the school can not afford to check that one. It would make a interesting science project for the class. Check with tuning forks, To determine frequency. Next check if it falls in the right range for this to happen, Next check why, Cracked bushing, wore brush's, So science, medical, and engineering project. Or you may come up empty handed. But being around a pulsing frequency, COULD. DO, THIS.???
