Providing basic hearing tests using remote computing technology

We administered pure tone and otoacoustic emissions testing to subjects in a distant community using remote computing technology. Fifteen men and 15 women ranging in age from 18-30 years were tested. An audiometer was used to measure subject pure tone thresholds. In addition, distortion product otoacoustic emissions (DPOAEs) data were recorded using a portable system. Both systems were interfaced to a PC which was connected to the local area network at Minot State University (MSU). An examiner at Utah State University, 1100 km away, could control both the DPOAE and the audiometer equipment at MSU. Overall, the pure tone means for the face-to-face and telemedicine trials were equivalent at each frequency. Moreover, DPOAE recordings exhibited equivalent results at each frequency for telemedicine and face-to-face trials. These results support the use of remote computing as a telemedicine method for providing pure tone audiometry and DPOAE testing to distant communities.
