  1. Note. RGD 0.5. Random gap detection subtest 500 Hz. Scores are in milliseconds.
  2. RGD 1. Random gap detection subtest 1000 Hz. Scores are in milliseconds.
  3. RGD 2. Random gap detection subtest 2000 Hz. Scores are in milliseconds.
  4. RGD 4. Random gap detection subtest 4000 Hz. Scores are in milliseconds.
  5. RGD C. Random gap detection subtest clicks. Scores are in milliseconds.
  6. HINT. Hearing-in-noise test. Scores are in dB signal-to-noise ratio. HINT SRT: binaural speech recognition threshold for sentences in quiet; HINT 1: noise and sentences delivered at 0° azimuth; HINT 2: noise delivered to the right ear (90° azimuth) and sentences delivered to the front (0° azimuth); HINT 3: noise delivered to the left ear (270° azimuth) and sentences delivered to the front (0° azimuth); HINT C: composite value calculated combining the previously three HINT conditions.
