| Total Participants | 31 | 18 | 30 |
For mean values, standard deviations are shown in (). PTA – pure tone average, EHF – extended high frequency, LENS-Q – Lifetime Exposure to Noise and Solvents – Questionnaire, MOS – Military Occupational Specialty. High MOS rating refers to a high probability of hazardous noise exposure associated with that MOS.
