Why do the way that DSL-IO targets for broadband (eg speech) and narrow band (eg pure tone) are displayed on Unity and Aurical differ?
This due to spectral density. The Aurical system applies a correction so that they are displayed the same. For the Unity there may be significant differences in the curves displayed, but this does not affect the actual measurement itself. The targets on the Unity are based on spectral density and therefore are lower than for the Aurical when a broadband signal is used. The targets on the Aurical are displayed in Equivalent SPL values (assuming the display setting is “FFT in Equivalent SPL”) Source: E-mail Amy Mclauchlan 11.04.
