Is the middle ear a transducer?
The middle ear is essentially a transducer that converts air oscillations in the outer ear (on the left) into fluid oscillations in the inner ear (on the right).
What is the floating mass transducer?
The Vibrant Soundbridge Floating Mass Transducer® (FMT) is part of a commercially available implantable hearing device in which the FMT can be placed in the round window niche (RW) or attached to a partial (V-PORP) or total ossicular replacement prosthesis (V-TORP) contacting the stapes head or footplate.
What acts as a transducer in the ear?
The Ear Transduction The ear is the peripheral receptor of the auditory system and, essentially, a mechanoelectrical transducer which converts sonic vibrations into an electrical signal, the receptor potential.
What kind of implant has a floating mass transducer that is placed on the ossicles?
SOUNDBRIDGE is an active middle ear implant that uses minuscule vibrations to provide excellent amplification with a natural sound quality. SOUNDBRIDGE uses a floating mass transducer (FMT) to turn electrical signals from the audio processor into mechanical sound vibrations.
What’s in the middle ear?
The middle ear consists of three bones: the hammer (malleus), the anvil (incus) and the stirrup (stapes), the oval window, the round window and the Eustachian tube.
How much does a middle ear implant cost?
Costs about $15,000-$30,000 per ear. Not covered by Medicare; some private insurers may pay.
How do middle ear implants work?
The implant works by directly moving the bones of the middle ear, or by vibrating the membrane window of the cochlea. In either case, it is designed to amplify sounds by adding extra movement into the natural hearing pathway. The middle ear implant relies on a working cochlea and hearing nerve.
Is the basilar membrane in the middle ear?
The basilar membrane is a stiff structural element within the cochlea of the inner ear which separates two liquid-filled tubes that run along the coil of the cochlea, the scala media and the scala tympani….Basilar membrane.

What is the purpose of the middle ear?
The primary function of the middle ear is to offset the decrease in acoustic energy that would occur if the low impedance ear canal air directly contacted the high-impedance cochlear fluid.
