Kerketta S et al. – The hearing loss is found to be at 6 kHz, thus the working areas of the subjects working at work zone should be regularly rotated in less noisy areas to reduce the exposure duration. High frequency noise protective device should be advocated among all the subjects in general and HEMMs operators in particulars. Regular audiometry test of all the subjects should be performed to identify the hearing loss of the subjects occurring at 6 kHz. It is essential to perform periodic maintenance of all the HEMMs to keep all the vehicles in good condition those are generating noise at dominating frequency of 4 and 6 kHz.
