Notes: Abstract A simple inexpensive electroacoustic instrument utilising the transforming properties of a half-wavelength acoustic transmission line has been developed for performing a simple screening test of the middle-ear pressure. This device monitors changes in the magnitude of the acoustic impedance of the tympanic membrane as the pressure difference across it is varied. A 25 db h.l. hearing test at 4 kHz is also included.
