About Us

Originally known as Foster Hearing Centers, Stan Foster started the company in the 1940’s. In the early 1980’s our name was changed to Foster Special Instruments when we began selling audiometric instruments to the Occupational Health industry. The hearing centers were later sold off and the company began adding additional instruments to our product offering.  Now with over 70 years in business, we are proud to represent the leading instruments in the Occupational and Safety industries.
