System 5000 - Our Premier System

The lab GUI image showh below is a view of the System 5000 User Interface in operation as it runs on our resident laboratory configuration. This GUI shows up on the Muse Receptor screen to enable our calibration. The user will rarely have any reason to modify these settings.

System 5000 accommodates symmetric and asymmetric hearing characteristics. The left two panels enable us to dial in the user's audiology which consists of measured hearing threshold elevations at standard half-octave frequencies.

The last two frequency bins, 12 KHz and 16 KHz, cannot be reliably measured with current audiology practices. But we provide the ability to set these anyway, since some users have requested them.

When hearing is symmetric and exhibits straightforward sensioneuro impairment, we can forego all these audiology settings and simply dial in one parameter to match the user's hearing. That parameter is something we call V-Tuning. That one simple control is sufficient to set the entire thing up. (In the language of our mathematics, we have managed to orthogonalize a problem with more than 300 dimensions.)

The Atten control is provided to reserve some headroom for our processing. The 4-position switch on the lower-right panel allows us to switch between various outboard make-up equalizers.
