About us

e3-hc-audiometrics-your-local-experienced-expertse3 HCI Audiometrics, an e3 Diagnostics company, is an amalgamation of three different companies that joined together in early 2013. The former companies were: Electro Acoustic Company (EAC), Health Care Instruments (HCI), and Sonic Medical Devices (SMD). Each of these companies has its own unique history. In addition to these three companies, selected personnel from the Southern California counterpart, Audiometrics, were brought to Northern California to be a part of e3 HCI Audiometrics.e3-hci-audiometrics-service-calibration

Our Individual Histories

eac-logoFounded by L. Glen Pew in 1952, Electro Acoustic Company (EAC) began as a part-time business calibrating and repairing audiometers, primarily in the greater San Francisco Bay Area. In the mid-1960s, it became a full-time endeavor. Interestingly, Glen Pew designed and built an automatic audiometer. EAC’s principal equipment line at this time was Maico. In 1974, the company expanded to include all of Northern California, Nevada and Utah. Also in that year, Ron Pew, his wife Sharon, and Glen’s son Stephen joined what had become a family business. EAC represented Beltone, Zenith, Tracoustics and other equipment lines. Glen’s son-in-law Dan Beesley joined the company in 1979. Ron Pew was instrumental in forming NASED (National Association of Special Equipment Distributors). On March 1, 2013, Ron Pew sold EAC to what is now known as e3 Diagnostics.


Health Care Instruments (HCI) began in 1992 as MSR California (founded and operated by Roger Ott and Brian Hillabush). In 1999, Ron Macon (brother-in-law of Brian) and Merlyn Lubiens purchased MSR California from Roger and Brian and changed its name to Health Care Instruments. In 2000, Ron Macon purchased Merlyn’s share of the company and assumed 100% ownership. Also in 2000, Dan Hatch joined the company as its CFO. In the ensuing years, HCI specialized in higher-end equipment (ENG/VNG, Real Ear, OAE, and ABR) though it serviced and sold equipment to a full range of clientele, from screening to diagnostic to clinical.  HCI excelled in particular as an exclusive manufacturer’s representative for Audioscan and Bio-logic. Ron Macon sold HCI to what is now known as e3 Diagnostics on January 31, 2013. He passed away on April 8, 2014.


Duane Hillabush, Brian Hillabush’s brother, began working in the field in 2007, first providing engineering and sound booth installations for MSR. At that time, his company was known as Sonic Acoustics. Duane even dabbled in building sound booths which he sold to MSR. In May of 2009, Duane retired from his former career in the roof truss business. Beginning in 2010, Duane provided booth installation and other services for Health Care Instruments. Also in 2010, Duane incorporated his business as Sonic Medical Devices. He began by representing and distributing for Maico and Otodynamics, later picking up Interacoustics. With four employees in early 2013, Duane sold Sonic Medical Devices to e3 Diagnostics on January 30, 2013.
