Tubephones & Accessories
Life Science Data Acquisition at its Best
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 participant’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
