The Welch Allyn TM 286 AutoTymp is a flexible screener for tympanometry, audiometry, acoustic reflex measurements. It is lightweight, portable, and designed to make detection and documentation of the middle ear pathologies fast and accurate.
The TM286 Auto Tymp is available with both 226Hz and 1Khz probe tones to accommodate testing for patients between the ages of birth through geriatric. The instrument is to be used by trained personnel only, such as audiologists, ENT surgeons, physicians, hearing healthcare professionals or personnel with a similar level of education. This device should not be used without necessary knowledge and training to understand its use and how results should be interpreted.
An optional soft-sided carrying case is available for portability. Also, a patient handswitch, patch cords, and earphone sound enclosures may be purchased as optional accessories.

Probe Tone
226 Hz, ±2%
Sound Pressure Level
226 Hz: 85.5 dB SPL, ±2.0 dB, measured in a 2.0 cm3 coupler
Harmonic Distortion
< 3%
Admittance (Compliance)
Range: 226 Hz: 0.0 to 1.5 cm3 or 0.0 to 3.0 cm3
Note:
The range is automatically selected based upon the amplitude of the compensated tympanogram.
The maximum uncompensated (ECV + tympanogram peak) admittance (compliance) range is 0 to 5.0 cm3.
ECV/cavity limits for initiating pressurization is 0.2 to 5.0 cm3. Compliance Accuracy: ±0.1 cm 3 or ±5%, whichever is greater.
Pressure Range
+200 to -400 daPa
Pressure Accuracy
±10 daPa or ±15%, whichever is greater
Rate of Sweep
600 daPa/sec except near tympanogram peak where sweep rate slows to 200 daPa/sec to provide better definition of peak compliance.
Direction of Sweep
Positive to negative
Tympanogram Test Time
Approximately 1 second
Gradient
Measurement of the tympanogram width taken at 50% of peak compliance.
Note:
1 daPa = 1.02 mm H20
The pressure sweeps to at least -100 daPa. To save test time, pressure sweep stops when tympanogram returns to baseline after -100 daPa.
Full pressure sweep for 5 cm3 from sea level to 7000 ft. altitude with no leak.
High compliance tympanograms (test time) will take somewhat longer.
Frequencies
500, 1000, 2000, and 4000 Hz for ipsilateral stimulation
Accuracy
±3%
Total Harmonic Distortion
< 5% for outputs less than 110 dB HL and <10% at 110 dB HL
Rise/Fall Time
5 to 10 msec
Transducers
Ipsilateral
Probe Assembly
Output Levels
Ipsilateral
500 and 4000 Hz: 80, 90,100 dB HL 1000 and 2000 Hz: 85, 95, 105 dB HL
Pressure
Reflex measures are set automatically to pressure at peak compliance with an offset of -20 daPa if peak pressure is negative and +20 daPa if peak pressure is positive.
Reflex Determination
Compliance change of 0.05 cm3 or greater
Reflex Test Time
1 to 12 seconds depending upon the number of ipsilateral test frequencies selected (4 maximum) and intensity required.
Note:
Ipsilateral stimuli are time multiplexed with probe tone (93 ms ON, 66 ms OFF).
Stimuli are presented at lowest level first. If there is no response, the intensity is increased by 10 dB until a response is detected or the maximum dB HL is reached.
