ABSTRACT:
An earphone cover, for attachment to an operative region of an audiometric testing device includes a body formed from a substantially antiviral, acoustically-transparent material, and is constructed for covering such operative region. The body is preferably formed as a polyethylene film with a thickness of about 1-mil. Anti-viral testing shows that the earphone cover is an effective barrier throughout a 60-minute exposure time to a viral organism described as .phi.X174 bacteriophage ATCC# 13706-B1. Acoustic transparency testing shows the earphone cover exhibits acceptable % total harmonic distortion and attenuation. A method of preventing patient cross-contamination associated with audiometric testing is also described. Both the structure and method are usable without affecting calibration of the audiometric testing device.
