Product Description

TM286 AutoTymp Tympanometer

The Welch Allyn TM 286 AutoTymp® provides flexible screening for tympanometry, acoustic reflex measurements and audiometry to meet your testing needs today and in the future.

The TM 286 AutoTymp is lightweight and portable. It is designed to make detection and documentation of middle ear pathologies fast and accurate.

Features and Benefits

  • Tympanometry, ipsilateral acoustic reflex testing, and manual or automated audiometry packaged in a single, user-friendly device
  • Multi-function capability enables management of ear health through detection and documentation of otitis media, perforated tympanic membrane, patent tympanostomy tube, ossicular disruption, tympanos
  • The tympanograms and the following summary information are clearly shown on the crisp LCD once the test is complete.
  • LEDs on the probe guide the tester through the test sequence. All test results can be printed on the internal printer.
  • The ASHA normal box can be shown as a guide on the display and printouts, if desired.
  • A hand-held probe is provided with versions providing 226 Hz only measurements.

Technical Specifications

Tympanometry Mode

  • 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
  • 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

Reflex Mode

  • 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
  • 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

Audiometry Mode

  • Frequencies: 125, 250, 500, 750, 1000, 1500, 2000, 3000, 4000, 6000, 8000 Hz
  • Accuracy: ±2%
  • Total Harmonic Distortion: < 2.5% (125 to 3000 Hz measured acoustically at maximum dB HL; 4000 and 6000 Hz measured electrically)
  • Audiometric Headset: Pair External earphones Type 51 cushions (60 ohms impedance). Headband force per ANSI S3.6 and IEC 645 (4.5 N ±0.5)
  • Insert Earphones: Ear Tone Insert Earphones (50 ohm impedance)
  • External Headset Earphones: 125 Hz: -10 to 50 dB HL; 500 to 6000 Hz: -10 to 90 dB HL; 250 and 8000 Hz: -10 to 70 dB HL
  • Accuracy: 125 to 4000 Hz ±3 dB; 6000 and 8000 Hz ±5 dB
  • Step Size: 5 dB
  • Signal-to-Noise Ratio: > 70 dB in 1/3 octave; less than -10 dB HL for levels less than 60 dB HL
  • Rise/Fall Time: 20 to 50 msec
  • Continuous: Tone is steady when present bar is depressed
  • Pulsed: Tone is pulsed at 2.5/sec (i.e., 200 msec ON, 200 msec OFF)
  • FM (frequency modulated): Tone is frequency modulated at a rate of 5 Hz, ±5%

Miscellaneous Data
