Bone conduction audio prothesis

The hearing prosthesis of claim 1 further comprising: An example mathematical expression for the transfer function is given below. In one embodiment, the computer contains a database of frequencies and amplitudes associated with a specific prosthesis recipient. This broader bandwidth enhances spatial hearing abilitywhich is a key limitation for SSD patients.

The hearing prosthesis of claim 1 further comprising output circuitry and an acoustic speaker, wherein the output circuitry is configured to create a signal for the acoustic speaker based at least in part on the first mechanical vibration signal measured by the first vibration sensor.

The hearing prosthesis of claim 26 further comprising a seismic mass, wherein the seismic mass is coupled to the sensor unit and is configured to tune Bone conduction audio prothesis sensor unit to adjust an output of the sensor unit.

Thus, the computer may also be configured to calculate a head-related transfer function from the first hearing prosthesis a to the second hearing prosthesis b. However, many features and functions may be equally applicable to other types of hearing prostheses.

In these cases, the head-related transfer functions may be used to calculate a filter to maximize constructive interference caused by the cross talk.

This binaural both ear fitting allows crosstalk between hearing prostheses a and b to be measured. The hearing prosthesis and vibration sensor may be integrated the same unit or may be connected together and attached to a recipient according to any of the configurations described herein.

For example, the computer may record the output of the vibration sensor The method of further comprising varying the amplitude of the electrical signal.

When the computer knows the impedance parameters associated with the recipient as well as the parameters of the impedance loada recipient-specific calibration can be achieved without the need to attach the hearing prosthesis to the recipient.

In one embodiment, the mechanical stimulus is based at least in part on an acoustic signal received by a microphone associated with the hearing prosthesis. In one embodiment, the mechanical stimulus e. Study participants wore SoundBite for 6 month.

The recorded amplitude may correspond to a voltage applied to the electromechanical transducer within the hearing prosthesis. The transcutaneous technology avoids several complications of the percutaneous bone conduction implants including skin reaction, skin growth over the abutment, and wound infection.

Additionally, the connections between elements may be wired or wireless. For example, the computer may cause the hearing prosthesis to create a stimulation signal with a known amplitude at a set of predetermined frequencies.

The method of claim 12 further comprising creating an acoustic output based on the measured first mechanical stimulus, and applying the acoustic output to an acoustic speaker. The person monitoring the conducted audio signal can assist with system diagnostics.

The methods and apparatuses described herein allow both hearing prostheses a and b to be measured at the same time.MEDICAL POLICY POLICY TITLE IMPLANTABLE BONE-CONDUCTION AND BONE-ANCHORED HEARING PROSTHETIC DEVICES POLICY NUMBER MP Page 2 [Note: Final page is signature page and is kept on file, but not issued with Policy.] insufficient evidence to support a conclusion concerning the health outcomes or benefits.

Audio Bone transmits music through your bones directly to your inner ear – so you can still hear everything around you.

Audio Bone is available in two different editions: Audio Bone and Audio Bone Adjustable. Audio Bone is our most popular product. It provides the best quality sound, and a stylish design. The hearing prosthesis may be a bone anchored hearing aid or other vibration-based hearing prosthesis, or any other type of hearing prosthesis configured to receive and process at least one signal from an audio transducer (such as microphone ) of the prosthesis and create a mechanical vibration output.

The Bonebridge (MED-EL, Austria) prosthesis is a semi-implantable hearing system: the BCI (Bone Conduction Implant) is the implantable part that contains the Bone Conduction-Floating Mass Transducer (BC-FMT), which applies the vibrations directly to the bone; the external component is the audio processor Amadé BB (MED-EL, Austria), which.

holds the external audio processor in place (Amadé BB) and transmits the signal through the coil to make this system transcutaneous. The Bone Conduction Implant (BCI) may be Active Bone Conduction Prosthesis: BonebridgeTM Zernotti, Bravo pocket beneath the periosteum.

Then, the BC-FMT should be.
