The American Institute for Voice and Ear Research shares space and resources with the Philadelphia Ear, Nose, and Throat Associates and The Voice Foundation at 219 N. Broad Street, Floor 10, Philadelphia, PA 19107.

Voice research resources include a comprehensive, extensively-equipped laboratory for acoustic, aerodynamic, vibratory and other phonatory assessments; strobovideolaryngoscopy rooms; and facilities for singing and acting voice analysis, research, therapy and training.

Ear research resources include comprehensive audiology facilities, special audiometric equipment for ultra-high-frequency audiometric testing, brainstem evoked-response audiometry, promontory stimulator testing, electroneuronography, eletrocochleography, otoacoustic testing, cochlear implant program and rehabilitation facilities, electronystagmography, and computerized dynamic posturography (CDP). Extensive occupational hearing loss research and management have been an integral and internationally renowned component of AIVER. University facilities are utilized for histologic, biochemical, genetic, non-human and other special research needs.
