About the Facility

The Auditory Laboratory contains several areas and stations that help support the work and research that is done for auditory research activites and efforts. See the Lab Layout.

Total Space:

  • 3400 sq. ft. (including lab, office, and secretarial areas)

Main Lab Space:

  • 1200 sq. ft. (consisting of one large open room)

Six Sound Booths:

  • For middle ear, auditory nerve, auditory cortex, otoacoustic emissions, endocochlear potential studies, and sound exposure.

Three Cell Biology Stations:

  • For in vitro analysis of hair cell function. These stations include suspension tables, Farraday cages, Zeiss microscopes, patch recording equipment, water microjet apparatus, video imaging equipment, photodiode motion detectors, and equipment to measure membrane capacitance.

Other Research Stations, dedicated to:

  • Single-unit recordings from cochlear nerve
  • Single-unit recordings from the auditory cortex
  • Laser-interferometry of the middle ear
  • Otoacoustic emissions

Histology Lab and Tissue Preparation:

  • Four dissection stations
  • Universal Zeiss and Zeiss inverted microscopes for histologic examination
  • Shared scanning electron microscope facilities
  • Laminar flow hood
  • Incubator
  • Noise exposure room (two chambers)

Additional Equipment:

  • Electrode pullers and microforge
  • Pipette impedance electrometer
  • Morphologic measuring system
  • Dissecting microscopes
  • 9 PC computers used for real-time, on-line control of experiments; data and image analysis, graph production, and word processing.
  • 5 PC computers are networked
