Equipment - ABR & DPOAE Work Station - Ann Arbor

Notice of Intent to Sole Source Requirement The Department of Veterans Affairs, VA Healthcare System, NCO 10 intends to negotiate a sole source order under FAR Part 13. The VA Ann Arbor Healthcare System requires an order for a ABR & DPOAE Workstation in accordance with FAR 13. The purchase will include the following items: Z-Series 4-DSP Bioacoustic System w/Attenuators and Optic fiber 4-Channel Pre-Amp/Digitizer and Low Impedance Headstage Electrostatic Loudspeaker - Coupler Model AEP/OAE Software for RZ6 Experiment Control Workstation 22 Inch Widescreen LCD Monitor 1/4" Free Field Measure Calibration Mic Kit Distortion Product OAE Microphone System 30 Needle Electrodes Cable Kit: BNC Cables, T-connector, BNC Female Adapter While there are commercial systems designed for obtaining auditory brain stem response (ABR) in people, these are not suitable for our animal studies.

Animal Studies require: Ability to acquire threshold measurements of Auditory Evoked Potentials in mice and rats. Ability to generate signals at different frequencies suitable for rodent hearing (up to 64kHz). Magnetic speakers for high frequency stimulation with detachable tips allowing them to be used in either free-field or closed-field use. Software for generation presentation sequences. Includes an integrated signal calibration program to calibrate transducers at frequencies up to 90 kHz.

Ability to generate an impulse noise exposure. Hardware with a stimulus bandwidth in excess of 80 kHz. The commercial systems for people do not have these necessary features to enable measurement in our animal models (rats and mice). In addition our studies require the ability to generate and measure Distortion Product Otoacoustic Emissions (DPOAE), which is possible with the requested Tucker Davis System and not in any other commercially available device.

We also study the Vestibular system and the Tucker Davis system can be configured to measure vestibular sensory evoked potentials (VsEP) an important metric in our studies. The associated NAICS code for this procurement is 334519. The vendor will be Tucker-Davis Technologies, Inc., 11930 Research Circle, Alachua, FL 32615. A firm fixed price contract is anticipated and shall be awarded.
