Offering Quality Sound-Based Products SInce 1981


Formed in 1981 to research non-toxic forms of pest control, Sonic Technology and its founders confirmed that high-frequency ultrasound could be used as a behavior modification technique to repel rats and mice from an area.  The result of that research was the PestChaser® ultrasonic rodent repeller, also referred to as an electronic rodent repeller, which was introduced the following year.  In the ensuing two decades, despite knock-offs and attempts at imitations by competitors, millions of PestChasers® were sold and successfully used to repel rodents around the world.  Six years after the PestChaser® line was sold to Woodstream Corp. in 2003, Sonic discovered another line of rodent repellers, manufactured by Innovative Technology, which Sonic felt was equal or superior in performance and design. Sonic began distributing these new and effective products with great success.


Over the past 3 decades Sonic has introduced a variety of dependable products including the popular SuperEar® and SuperEarPlus® lines of Personal Sound Amplifiers; the AudioTech Probe™  Electronic Diagnostic Stethoscope used by auto mechanics, machinists, plumbers and HVAC professionals for detecting leaks and mechanical problems; and the ElectroSensor a popular hand held Electro Magnetic Field Detector (or gauss meter) used by professionals and homeowners to detect potentially dangerous sources of EMFs, as well as by paranormal investigators and ghost hunters.


In 1999, Sonic introduced the original ToneMaster 2100 Electronic Muscle Stimulator and Personal Fitness System.  The ToneMaster quickly became one of the most popular and successful products of its kind, with thousands sold around the world via television, magazine and the internet.  In 2007, Sonic redesigned the ToneMaster to incorporate many new features that our customers had requested.


The latest successor to the ToneMaster is the ElectroMassage System EMS2200 (to be replaced in 2010 by the new ToneMaster TM2200™…smaller, more portable and with a host of popular features. The unit provides the ability to operate from a 9 volt battery as well as from household current.  It also includes a timer and greater choices of pulse duration and strength. The muscle stimulator is ideal for athletes, therapists or anyone desiring to augment a muscle-toning regime.


Sonic Technology will continue to refine and improve its products…and back them with personal service, value, honesty and integrity.  That was our mission in 1981 and it remains our corporate focus almost 30 years later.
