Setting The Clinical Standard

Grason Stadler had a vision over 65 years ago to produce audiologic equipment that is accurate, easy to use and functional. Founded in 1949, GSI provided instrumentation for research and clinical measurement in the field of hearing. Over the past 6 decades, our vision has become the gold standard for audiometric testing. Today the diversity of hearing health care professionals and clinical settings is great, each with varying needs. GSI offers a full line of audiometers, middle ear analyzers, otoacoustic emissions and auditory evoked potential instruments for clinical, diagnostic and screening environments. GSI couples the comfort and tradition of testing on a dedicated device with the convenient one button data transfer to a PC. GSI has been setting the clinical standard worldwide in audiometric instrumentation health professionals in over 70 countries.
