DASY8/6 Module HAC V1.2: Packed with New Features

Simplified procedures, additional viewer options, and more: SPEAG has further improved the user experience when testing compatibility with DASY8/6 Module HAC V1.2 between a wireless device and hearing aids according to ANSI C63.19-2019.

After the successful launch of the first version of our hearing aid compatibility module, DASY8/6 Module HAC V1.0, in November 2021, SPEAG has further improved the features and workflow of the module based on valuable customer feedback. Streamlined procedures and improved visualizations now make it easier and smoother to demonstrate compliance with ANSI C63.19-2019.

Compatibility with Windows 10/1

Module HAC V1.2 supports the latest hardware revision of the Audio Magnetic Measurement Instrument (AMMI). Based on the Roland Rubix22 USB audio interface, it is fully compatible with Windows 10/11.

Simplified Procedure

In Module HAC V1.2, the hearing aid compatibility test arch position and probe calibration results are persistent. It is no longer necessary to import them after restarting the Jupyter notebook – the last used values are automatically restored.

AngleCalibration

System response during probe angle determination

 

Automated Calculation of Codec / System Delay

The audio signal emitted by the wireless device under test may be delayed due to the codec latency. In Module HAC V1.2, this parameter no longer needs to be evaluated manually: it is now determined automatically in post-processing.

Additional Viewer Options

The field viewer comes with many new features: for example, users can now edit the color bar range and export all displayed data. In addition, the spectrally weighted undesired magnetic noise can now be visualized.

FieldViewer

H-field distribution for a Telephone Magnetic Field Simulator (TMFS) measured in transverse orientation. The color bar range is editable

 

Intuitive Communication System User Interface

The communication system selection has also been further improved: the layout is more user-friendly and the most frequently used test channels (low/middle/high) are more prominently highlighted.

Improved Post-Processing of Undesired Audio Band Magnetic Field

The post-processing algorithm for evaluating the undesired magnetic field in the audio band has been improved to avoid overestimation of when low-frequency components dominate.
