Phone Speech Recognition Improvement in Noisy Environment: Use of a Bluetooth Accessory.

Objective: To evaluate speech understanding in noise and patient satisfaction using the new Cochlear Wireless Phone Clip device.

Material And Methods: Twenty-nine experienced cochlear implant (CI) users (>6 months usage) were situated in a soundproof room where a 65 dB SPL Spanish cocktail noise was generated continuously from 4 loudspeakers. Lists of disyllabic words were presented through the clinic landline telephone to the patients.

Wireless inertial measurement unit (IMU)-based posturography.

Background: Classical posturography techniques have been recently enhanced by the use of different motion tracking devices, but for technical reasons they are not used to track directly the body spatial position of a subject.

Objective: To describe and clinically evaluate a wireless inertial measurement unit-based mobile system to track body position changes.

Methods: The developed system used a calculus transformation method using the acceleration data corrected by Kalman and Butterworth filters to output position data.

[Surgical implantation of the fully implantable middle-ear hearing device].

The new fully implantable middle ear device (CARINA) is useful in sensorineural, conductive and mixed hearing loss. Surgical implantation of this device in the different types of hearing loss is similar in some aspects but differs in others. Consequently, we describe the surgical procedure in sensorineural and in conductive hearing loss separately.
