FONIX 7000 v1.62 Frye Electronics is pleased to announce software version 1.62 for the 7000 Hearing Aid Test System. This is a small “bug fix” release that does not add any new features or change the user interface or RS232 protocol in any way. In software version 1.62, the method for performing real-ear spectrum analysis measurements has been improved. Previously, noise reduction averaging was performed in the time domain before the FFT was performed. Although this method is preferred for normal measurements using the built-in test signals, it is not desirable for spectrum analysis measurements using an external input signal. In the new release, noise reduction averaging in real-ear spectrum analysis measurements will now be performed in the frequency domain (after the FFT). Coupler spectrum analysis was already using the frequency domain noise reduction averaging method, so this upgrade only affects real-ear spectrum analysis measurements. No other changes were made to the 7000 software.
