WaveFit is WaveTech’s software for programming digital hearing aids, designed for use by speech and hearing professionals during user tuning sessions. The Software is fully presented in Portuguese, in order to make it easier for operators to take advantage of all the subtleties of performance evaluation and understanding and application of user perceptions and manifestations. It eliminates, therefore, any losses of unsatisfactory application of the standard language.

The “WaveFit” is compatible with the unified NOAH platform, available for the SUS, and can be customized of the Portuguese language, promoting immediate adaptation. The NOAH platform is the unified hearing aid database supported by all major international manufacturers.

WaveTech software is capable of communicating with HI-PRO programmers (the world’s leading hearing instrument programmer) and also with the ON-SEMI DSP “Programmer”. It presents a driver and has implemented the protocols of communication of said programmers, both to record parameters and to read their current state in the connected prosthesis. A graphical interface was developed in order to allow different levels of speech therapist action.

Due to the relatively large number of algorithms and options present in the device, each one with several parameters, it is convenient to automate tasks of greater complexity, allowing, however, their manual manipulation, if it is considered necessary. Thus, in the software is inserted a basic adjustment mode, to reduce the period required for the change, and an advanced mode, for particular cases that contains important differentials.

Another relevant feature concerns the before and after technique, similar to the work system used by ophthalmologists. In an adaptation, the professional changes a parameter and asks the patient if there was improvement or worsening. In the WaveTech device, with each change, the software registers the difference and, by dichotomy, it reaches an optimum point. In other systems, setpoints can be infinite, which makes the activity more complex and diffic

A third important feature is that WaveTech software has what is called a psychoacoustic character. This means that he interprets the patient’s perceptions of sound and transfers them to the algorithm.
