Introduction: Occupational noise exposure can negatively affect hearing acuity and temporal processing, particularly in workers like bus drivers who are regularly exposed to high noise levels. Professional bus drivers, exposed to prolonged noise from engines and traffic, are particularly at risk for NIHL, but remain the least studied in India. This study aimed to assess the impact of prolonged noise exposure on hearing, temporal processing abilities, and speech identification among bus drivers, comparing them with a control group of non-noise-exposed office workers. Methods: Sixty-eight bus drivers and thirty office workers (control group) participated in this cross-sectional study. The participants in the experimental group had a mean age of 37.5 years (range = 29 years to 46 years) and the duration of service as drivers ranged from 1 to 9.8 years. Hearing acuity was assessed through pure tone audiometry, while temporal processing was evaluated with gap detection and amplitude modulation tasks. Speech identification was tested in ‘quiet’ and ‘in noise’ conditions. Results: Participants in the drivers' group had a mean pure tone average of 18.56 dB HL in the left ear and 19.04 dB HL in the right ear and the difference between the two groups was statistically significant.  The mean gap detection threshold of participants in the drivers group (3.10 milliseconds) was significantly different from that of participants in the control group (2.44 milliseconds) as were the amplitude modulation detection thresholds especially for higher modulations at 128 Hz and 256 Hz. Speech identification scores for monosyllables in quiet were not significantly different between the two groups in contrast to speech identification in noise score (at 0 dB and -5dB SNR conditions). Conclusions: Prolonged noise exposure not only causes a decrease in hearing sensitivity but also impaires temporal processing abilities. Impaired temporal processing may have contributed to difficulties in speech identification, especially in noisy environments, highlighting the significant impact of noise on auditory function in occupational settings.
