Evidence for the Use of a New Patient-Centered Fitting Tool

A new patient-driven fitting tool called SoundPoint provides the patient with a means for fine-tuning a hearing aid by moving a pointer on a computer display or Apple iPad™ screen. Movement of the pointer to different areas of the screen results in instantaneous changes to the frequency shaping, gain, and compression parameters of the hearing aid.

High Frequencies and Microphone Placement Lead to a New Type of RIC Hearing Aid

A high frequency boost occurs when the hearing aid microphone is moved from the top of the ear (as in BTEs) to somewhere inside the auricle (as in ITEs)—with potential benefits in directivity and localization. A new microphone and receiver in the canal (MaRiC) design incorporates a small canal-worn module that contains both the microphone and receiver to take maximum advantage of the high frequency focusing ability of the auricle.

V & V and Its Impact on User Satisfaction

Verification and validation (V & V) are clinical tools to ensure functionality of hearing aids as well as individual patient benefit. However, they are not always employed by clinicians, even though they have been found to be correlated with user satisfaction. Rationale and research into the benefits of verification and validation measures are discussed, in addition to ways to implement them into clinical practice.
