NTRODUCTION
Thank you for purchasing a Welch Allyn MicroTymp 4, a hand-held, portable tympanometer that
will give many years of reliable service if treated with care. The instrument performs two types
of measurement:
Tympanometry is used to measure the admittance of the tympanic membrane and middle ear
at a fixed frequency over a range of pressures.
Acoustic Reflex tests are used to measure stapedial reflexes. The MicroTymp 4 measures
ipsilateral reflexes and, when selected, reflex measurement is automatically carried out after a
tympanogram is taken.
Features
 Automatic measurement of ear canal volume, tympanic admittance peak, placement of
the peak and the gradient
 Automatic detection of stapedial reflexes
 Up to 32, dual-ear patient tests can be stored in non-volatile memory
 Configurable settings for user preferences, held in non-volatile memory
 Printout of data to a printer
 English, German, French, Spanish, Portuguese or Italian operating language (selectable by
the user)
