Abstract
Is it essential to maintain the air pressure in the monitored ear equivalent to that of the middle ear pressure while measuring stapedius
muscle reflex threshold? It is customary to maintain the air pressure in the monitored ear equivalent to that of middle ear pressure while measuring stapedius reflex threshold. It is logical because reflex change could be easily detected only if the tympanic membrance is at its maximum compliance. This can be achieved when the air pressure an either side is the same.
