Table 1.
Thresholds from Exemplar Older Adults. All measures collected on three subjects with absent F0 in the sABR (O-1 to O-3) as well as the older adult with the strongest F0 (O-4) and the group means and standard deviations.
| Subject | F0 SNR | Summed SNRa | Mistuned Harmonic | Masking Release | PTAb | 8000 Hz Threshold | Age | Cognitive Screenc |
|---|---|---|---|---|---|---|---|---|
| O-1 | 0 | 12.01 | 3.00 | 7.95 | 16.7 | 35 | 69 | 25 |
| O-2 | 0 | 14.58 | 1.00 | 10.17 | 13.3 | 35 | 71 | 29 |
| O-3 | 0 | 28.67 | 1.08 | 9.43 | 11.7 | 15 | 67 | 30 |
| O-4 | 17.38 | 51.69 | 3.40 | 12.13 | 6.7 | 30 | 66 | 27 |
| O-Mean (s.d.) | 9.52 (5.65) | 34.49 (14.61) | 1.66 (0.85) | 9.15 (2.23) | 12.0 (4.4) | 29.6 (15.5) | 69.7 (4.4) | 27.1 (1.8) |
a
The summed SNR for the sABR response was the sum of the first five spectral components, H1-H5.
b
PTA = Pure tone average of audiometric thresholds 1000, 2000, and 4000 Hz.
c
All cognitive screen results presented here were obtained using the Montreal Cognitive Assessment.
