“…Although originally not designed for researching the middle ear function, many early studies did provide insight into this issue (for a review, see Arnold & Schindler 1963). Largely based on these studies, the following beliefs have become popular: ECP affects the middle ear conduction of low-frequency sounds more than highfrequency sounds, and positive ECP has a greater effect than negative ECP (for reviews, see Rasmussen 1946;von Békésy & Rosenblith 1951).…”

“…Historically, our knowledge pertaining to the effect of MEP primarily originates from earlier research on hearing sensitivity and loudness perception of sounds in humans under a varied ear canal pressure (ECP), which was employed to simulate the MEP effect (for reviews, see von Békésy & Rosenblith 1951;Arnold & Schindler 1963). In follow-up systematic studies using modern audiometry, the effect of MEP on hearing thresholds was also simulated with ECP variations (Truswell et al 1979).…”

Effects of negative MEP and ECP variations on DPOAEs in human ears are comparable, to a great extent, to findings from previous studies on hearing sensitivity in humans and tympanic membrane vibration at the umbo in human temporal bones. The present study demonstrates that positive ECP can be used to simulate negative MEP in research on the middle ear function in live humans. Results also suggest that long-lasting beliefs regarding the ECP effect on the middle ear conduction should be amended: (1) only positive ECP, not negative ECP, attenuates sound transmission more for low frequencies than for high frequencies, and (2) positive ECP has a greater effect than negative ECP only for low frequencies and not for high frequencies. Discussion of the present results together with those from previous studies sheds light on the middle ear dynamics under diverse pressure changes across the tympanic membrane and proposes that distorted configuration of the tympanic membrane and ossicular chain is the key factor in the effect of MEP or ECP on the middle ear sound transmission for low frequencies.
