Acoustics:
the science of sound
Audiology: the study of the hearing mechanism
Biocompatible: capable of being used within the
body without adverse effects.
Electrode: can be used to deliver electricity to
the body for stimulation or to receive electricity from
it to detect and record signals.
Hermetically: made airtight by fusion or sealing.
Hermetisation: process of sealing or fusing and
removal of air.
Microphone: an instrument which is capable of transforming
the air-pressure waves of sound into changes in electric
currents or voltages.
Neurotransmitter: a chemical substance, given off
by the ends or terminals of a nerve cell or fibre affecting
the next nerve cell or fibre in the chain, allowing
a message to be passed between the cells or fibres.
Otolaryngology: Otolaryngology (pronounced oh/toe/lair/in/goll/oh/jee)
is the the medical and surgical management and treatment
of patients with diseases and disorders of the ear,
nose, throat (ENT), and related structures of the head
and neck.
Otology: the science of the ear and its diseases.
Phonetics: the science of speech sounds and their
production.
Piezo-electric microphone: a microphone containing
crystals that convert changes in pressure into electricity.
Potentiometer: an instrument for measuring direct
current electromotive force or potential differences.
Prostheses: an artificial part to replace a defective
body part, such as an artificial leg or an eye.
Sensori-neural deafness: a defect lies in either
the cochlea or the transmission of sound signals to
the brain once they have left the cochlea. This form
of deafness tends to occur with age, and is accelerated
by exposure to loud sounds.
Speech processor: a device which analyses information
and converts it into an electrical code.
Tender: offer made in writing to provide a service
or product at a set cost.
Titanium: a metallic element.
Transmitting coil: The coded signal travels via
a cable from the speech processor to the transmitting
coil in the headset. Radio waves from the transmitter
coil carry the coded signal through the skin to the
implant inside the ear.
