Critical flicker fusion frequency, India Post, noise at work, productivity pattern.
Being a backbone of Indian economical structure, India post is serving India not only by means of delivering mails also with every banking facility to its citizens unlike other large part of world post. Literature is failing to provide any occupational health related work on these Indian postal workers. The common finding from several post offices by the authors was congested crowed within each post office premises and obvious noise which is beyond any standards during working hours. So the principle aim of this study is to investigate effect of work environment noise level on blood pressure, mental fatigue and productivity of Indian postal assistants. Generally, Indian postal workers can be classified into two groups: Postal assistants and postmen. Authors excluded postmen group from this particular study as they have to do door to door services which may alter environmental and physiological factors very frequently. Usually postal assistants need to do their assigned work behind a particular counter situated at one specific post office premises. This study results show systolic and diastolic blood pressure had strong positive correlation with post office environment noise. Though critical flicker fusion values were low in this subject group, became lower with increasing working environmental noise range. Their productivity had strong negative correlation with noise level. These postal assistants having high risk of psychological burden as well occupational stress due to daily long term exposure of work environmental noise. To prevent further burden regular work place noise monitoring and noise control processes need to be implemented soon.
