Introducing the Electronic Tuning Fork – an Innovation to Detect Ear Blockage

Manual tuning forks have been used for hearing health care since Weber in the late 18th century discovered a process for identifying ear blockages often due to wax, fluid or other diseases of the ear.

Summus Hearing  Solutions and TeTo Technologies are pleased to announce a major electronic upgrade for wide use by physicians, audiologists and other professionals concerned with hearing status as well as by consumers at home.

The Electronic Tuning Fork (ETF) is easily hand-held, includes a rechargeable battery, and at the press of a button produces a 500-hertz tone.

When applied to a person’s forehead and one ear is plugged at a time, the  ear is likely blocked if the sound does not appear to get louder. On the other hand, if the sound does get louder, the ear is likely not blocked indicating no significant air-bone gap.

When appropriate, a follow-up audiogram is recommended and provided virtually by the TeTo testing/interpretation engine. The process is quick, typically completed in under five minutes, Related instructions and reports are made available in a  simple to understand software solution. 

“Extensive applications are possible for patient treatment in clinic, as well as for hearing conservation programs and school screening. Follow-up and corrective action when needed are facilitated efficiently and at a minimal cost.” 

Distribution and a simple demo also make the ETF a valuable wellness instrument for home use, much like the portable blood pressure monitor has become. 

Inquiries are welcome as supply is scheduled to be available by March 2021. The price point is targeted to be under US$100.
