# Geoffrey R. Ball

Geoffrey R. Ball (born 1964) is an American physiologist specializing in Biomechanics and the inventor of the VIBRANT SOUNDBRIDGE active middle ear implant – a medical device designed to treat his own hearing loss.
Ball has a Bachelor of Science from the University of Oregon (Human Development & Performance – majoring in physiology & biomechanics) and a Master of Science from the University of Southern California (Systems Management). Ball co-founded medical device company Symphonix Devices Inc, which focused on the development of middle ear implants and introduced the VIBRANT SOUNDBRIDGE to the market. Since 2003, Geoffrey Ball has been a Chief Technical Officer at hearing implant manufacturer MED-EL in Innsbruck, Austria and has numerous international patents registered in his name.

## Background

As a child, Geoffrey Ball suffered a severe fever attack and developed severe sensorineural hearing loss. Conventional hearing aids were tried as a treatment, however, these brought no benefit. As a young man, he showed interest in active middle ear implants but was advised that the technology was only in its first development phase and therefore could not be used to treat his hearing loss. After completing a Bachelor of Science from the University of Oregon (Human Development & Performance – majoring in physiology & biomechanics) and a Master of Science from the University of Southern California (Systems Management), Ball worked for many years in the fields of neuroscience, biomedical and auditory research. His most notable development during this period was a new type of Laser Doppler Vibrometer, which used signal processing software developed in cooperation with Jont Allen from Bell Labs. The device was the most sensitive optical vibrometer ever developed at the time. Ball was able to use this device to build and test small high-fidelity transducers.
This work led to the development of the Floating Mass Transducer (FMT), a minute electromechanical converter that turns electrical signals into mechanical vibrations. The FMT could be attached to the ossicles, the smallest bones in the body that transmit vibrations from the eardrum to the inner ear. Using this technology, Ball’s team developed the VIBRANT SOUNDBRIDGE, a middle ear implant that comprises an implantable part, known as the VORP, and an audio processor. The device actively vibrates the bones of the middle ear and can be used to treat mild to severe sensorineural hearing loss, as well as conductive or mixed hearing loss. It is often used as an alternative for patients who receive no benefit from hearing aids.
Geoffrey Ball was himself one of the first patients to be implanted with the VIBRANT SOUNDBRIDGE and is currently a bilateral user. He is the only living person known who was implanted with a medical device to cure a chronic medical condition, that he also invented. He continues to use a middle ear device in one ear and is also implanted with a cochlear implant in his second ear.
Ball’s company, Symphonix, was launched in 2011 and later sold to hearing implant manufacturer MED-EL, where he now works as a Chief Technical Officer. The VIBRANT SOUNDBRIDE is still produced by the company today. At MED-EL, Ball also supported the invention of the BONEBRIDGE, the world’s first active transcutaneous bone conduction implant. The device also consists of an internal implant and an external audio processor and can be used to treat conductive and mixed hearing loss, as well as single-sided deafness.

## Personal life

Geoffrey Ball was raised in Silicon Valley, California.
Since 2003, Geoffrey Ball has lived just outside Innsbruck, Austria with his wife and son.
He is the author of his 2011 autobiographical book "No More Laughing at the Deaf Boy" (288 pages, Haymon Verlag, Innsbruck-Vienna) that tells the story from his childhood to the creation and sale of his company Symphonix Devices Inc.
His personal experiences as a child with hearing loss has also led Geoffrey Ball to launch “Ideas 4 Ears” young inventor’s competition that encourages children to create innovative ideas that help people with hearing loss.

## Patents

Geoffrey Ball has over 102 issued and pending US and international patents covering 26 patent families in the field of hearing implants, drug delivery, neuro-stimulation and other implantable medical devices.
