EPL Cochlear Function Test Suite

The Eaton-Peabody Laboratories Cochlear Function Test Suite (CFTS) performs acoustic calibrations and basic assays of cochlear function in laboratory animals. The CFTS is a package of programs written in LabVIEW that control digital stimulus generation and data acquisition using National Instruments input/output boards. The programs are already compiled and do not require a LabVIEW license to run. This means, however, that they cannot be changed. If a user wants to change the labeling or functionality, the underlying LabVIEW programs (called virtual instruments, or “VI’s”) can also be downloaded. Using these VI’s requires the LabVIEW programming environment and a LabVIEW license (these can be obtained at http://www.ni.com/). The basic elements of LabVIEW are relatively easy to learn so that small changes (changing the labeling or adding an additional input) might be done by an experimenter who has little programming or engineering background.

The cochlear function tests and procedures are:

  • Acoustic Calibrations
  • Auditory Brainstem Response (ABR) input-output functions
  • Compound Action Potential (CAP) input-output functions
  • CAP tuning curves
  • Distortion Product Otoacoustic Emissions (DPOAE) input-output functions
  • Basic data-analysis routines such as creating equal-response contours (DPOAE “tuning curves”) from multiple DPOAE level functions
