Graph 1Comparison of awareness about the effects of noise in the exposed group (n=65) and not-exposed group (n=50).
Graph 2Auditory and extra-auditory complaints and symptoms in the exposed (n=65) and non-exposed (n=50) groups.
Audiograms in the exposed group (GE) and the non-exposed group (GNE) to firearm noise (N=104).
| Audiogram classification | Exposed group (n=56) | Non-Exposed (n=48) | |
|---|---|---|---|
| Normal auditory thresholds | 75% (42) | 100%(48) | 0.0001 |
| Suggestive of | 25% (14) | 0%(0) | 0.0001 |
Student's t test; p< 0.05.
Results of TOAE in the exposed group (GE) and the non-exposed group (GNE) (N=104).
| TOAE | GE (n=56) | GNE (n=48) | |
|---|---|---|---|
| Present – bilateral | 21.42% (12) | 54.16% (26) | 0.0008 |
| Absent – bilateral | 58.92% (33) | 35.41% (17) | 0.0186 |
Student's t test; p< 0.05.
