NIOSH 1968 May:25 pages
Hearing threshold shifts are measured in subjects at 500 to 3000 hertz after exposure to fatiguing noise, and before and after administering Robaxin, Soma, Miltown, or Valium, with comparison to a placebo, to determine muscle relaxant effects on noise induced hearing threshold shifts. Test results indicate no effects by the muscle relaxants, contrary to a hypothesis that the drugs, in affecting the normal reflex response of the middle ear, would cause greater shifts.
