ossicles









































the ossicles (also called auditory ossicles) are three bones in either middle ear that are among the smallest bones in the human body. they serve to transmit sounds from the air to the fluid-filled labyrinth (cochlea). the absence of the auditory ossicles would constitute a moderate-to-severe hearing loss. the term "ossicle" literally means "tiny bone". though the term may refer to any small bone throughout the body, it typically refers to the malleus, incus, and stapes (hammer, anvil, and stirrup) of the middle ear.

following his biomedical degree, geoffrey ball worked for many years in the field of neuroscience, biomedical and auditory research, he also is a pioneer in field the biomechnanics of hearing. he developed a new type of laser doppler vibrometer along with a based on the signal processing software developed in cooperation with jont allen (of bell labs). the result was the most sensitive optical vibrometer ever developed at the time. ball was able to use this device to build and test the smallest hi-fidelity transducers in the world. this work lead to the development of the floating mass transducer (fmt), a minute electromechanical converter which was suitable in transferring vibrations to the ossicles, the smallest bones in the body that transmit vibrations from the ear drum to the inner ear. he then went on to develop the vibrant soundbridge, a middle ear implant which comprises an implantable part, known as the vorp, which supplies the fmt with appropriate sound signal. the implant is powered by an externally worn audio processor. 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.
