GSI 39 Auto Tymp

GSI 39 Auto Tymp

Flexible, screening product for tympanometry, acoustic reflex measurements and audiometry



The GSI 39 Auto Tymp is lightweight and portable.

It is designed to make detection and documentation of middle ear pathologies fast and accurate.

 

TECHNICAL SPECIFICATIONS :

PROBE TONE: Frequency: 226 Hz +⁄- 2%
Intensity: 85.5 dB SPL +⁄- 2.0 dB; measured with an IEC 60318-5 2 cc coupler
Harmonic Distortion: < 3%
COMPLIANCE: Range: 0.0 to 1.5 cm3 and 0.0 to 3.0 cm3
Note: Range is automatically selected based on amplitude of the tymp peak.
Accuracy: +⁄- 5% or +⁄- 0.1 cm3, whichever is greater
PRESSURE: Range: +200 to -400 daPa
Setting The Clinical Standard
Accuracy: +⁄- 10 daPa or 15%, whichever is greater, measued in 0.5 to 2.0 cc cavities
Sweep Rate: 600 daPa/sec, except near tympanogrm peak where sweep rate slows to 200 daPa/sec to provide better definition of the peak compliance
Sweep Direction: Positive to negative
Gradient: Tymp pressure width at 50% of peak compliance
Test time: Approximately 1 second
REFLEX: Frequencies: 500, 1000, 2000, and 4000 Hz
Accuracy: +⁄- 3%
Total Harmonic Distortion: Rise/ Fall Times: 5 to 10 msec
OUTPUT LEVELS (MEASURED WITH A 2CC COUPLER): IPSI
- 500 and 4000 Hz: 80, 90, 100 dB HL, +⁄- 3 dB
- 1000 and 2000 Hz: 85, 95, 105 dB HL, +⁄- 3 dB
CONTRA
- 500, 1000, 2000, 4000 Hz: 90, 100, 110 dB HL, +⁄- 3 dB
Note 1: Stimuli are time multiplexed with the probe tone (93 ms ON, 66 ms OFF);
Note 2: Contra available on versions 2 and 3 only.
Pressure: Automatically set to pressure at peak compliance with an offset of + or – 20 daPa depending on location of peak compliance
Determination of reflex present: Compliance change of 0.05 cm3 or greater
Test time: 2 to 12 second
