TABLE 3.
Group | 1 kHz (%) | 3 kHz (%) | 4 kHz (%) | 6 kHz (%) |
---|---|---|---|---|
Veteran high noise | 99.95 | 99.75 | 99.05 | 93.90 |
Veteran low noise | 51.30 | 62.05 | 64.45 | 66.60 |
Non Veteran firearms | 99.40 | 97.10 | 94.30 | 86.65 |
The probability that noise exposure group mean ABR wave I amplitude is lower than in the non Veteran control group is shown for a 110 dB p-pe SPL stimulus at each tested frequency. These probabilities are calculated from the Bayesian regression analysis. The highest probabilities are seen in the Veteran High Noise and non Veteran Firearms groups.
ABR indicates auditory brainstem response.
