Alteration in auditory threshold and loudness measurement according to bDLF.

In order to analyse whether the DLF alterations occurring at the bDLF might also influence auditory threshold and perceived loudness scaling, a two-way repeated-measures ANOVA was performed for various frequencies around the bDLF (Fref, bDLF–1/8 octave, bDLF and bDLF+1/8 octave) and for the various times of rehabilitation (before, and at 1 month, 3 months and 6 months). However, no significant effect of auditory rehabilitation on hearing threshold (F(3,24)=0.422, p=0.739) or on loudness matching performance (F(3,24)=1.508, p=0.238) was found at any of these frequencies.
