High-Frequency Filtered (HFE) and Low-Pass (HFE-LP) Lists
Data on patients with ski-slope hearing loss indicate some of these individuals
benefit from extended high frequency amplification (full bandwidth response),
while others perform poorer with a full bandwidth response.
High frequency emphasis was added to the QuickSIN recordings using the gain
values prescribed by the FIG6 fitting formula for 65 dB inputs, using an
audiogram with a 60-70 dB ski-slope loss.
The HFE-LP recordings were generated by low-pass filtering the HFE recordings
with a brickwall filter set at 2.5 kHz.

By comparing the results obtained with the HFE and HFE-LP lists, it may be
possible to determine whether or not extended high frequency amplification is
useful for an individual having a ski-slope hearing loss. For a test accurate
to 1.9 dB, four HFE lists and four HFE-LP lists are required.
