Ear Tubephone
Part #: OUT101A, OUT101E, OUT101T

Use the OUT101A tubephone to deliver clicks and tones in auditory evoked response applications (e.g., ABR auditory brainstem response). The Tubephone transducer attaches to a short, flexible, plastic tube, which fits into the subject’s ear(s) with the aid of a foam tip. Use of the Tubephone reduces ambient noise and bone conduction problems, which can interfere with auditory response recordings. Furthermore, because the Tubephone provides a 1 msec acoustic signal delay (due to plastic tube), it automatically separates true response from electromagnetic artifact resulting from speaker activation.

Advantages 

  • Incorporates “”touch-proof”” electrical connection for safety
  • Smooth frequency response
  • Provides 30+ dB external noise exclusion—equivalent to a single-wall booth when used with deeply-sealed foam eartips
  • Provides 70+ dB isolation (interaural attenuation) between ears; reduces the need for masking
  • Reduces test/retest variability compared to supra-aural earphones
  • Eliminates test errors due to collapsed ear canals

Accessories
