简要总结
Fatigue is one of the most common non auditory effect in occupational noise exposed population.
According to previously done studies, listening related fatigue is an early symptom of noise induced hearing loss. Population with prolonged occupational noise exposure who has listening related fatigue are at high risk of NIHL.
Assessment of listening related fatigue using Indian version of Vanderbilt Fatigue Scale - Adult will help in identification of the people who are at risk of developing NIHL.
Hearing screening will be done using potable audiometer and otoscope. The audiometry is done using modified Hughson -Westlake method. Pure tone average for air conduction threshold will be obtained at 500 Hz, 1kHz, 2kHz and 4kHz frequencies.
A self-administered one-minute noise screening is done. The subject is instructed to select any single option and the options given are never, every few months, monthly, weekly and daily. The scores range from 0 for never and 4 for daily. The noise score is calculated by calculating the sum of scores obtained in 3 questions. Scores of 0 to 4 represents lower risk and 5 and above represents higher risk. Subjects with higher risk and noise exposure of 85 dBA for 8 hours will be selected for the study.
Individuals under medication and treatments like chemo, radiation therapy, pain killers, heart drugs and antidepressants and individuals with systemic illness are not included in the study.
The study procedure is explained to the participants and the consent forms are obtained study participants.
Indian version of VFS-A is given to each subject to evaluate the listening related fatigue and the participants are instructed regarding the self-administration of the questionnaire. The VFS-A has 4 domains which includes Cognition, Emotion, Social and Physical. There are 2 sets of questions. For each item in the first set of questions, the subject has to select any single response from 0 being Never/ Almost never to 4 being Almost Always/Always. For each item in the
second set of questions, the subject has to select any single response from 0 being Strongly disagree to 4 being strongly agree.
