A study of effect of noise exposure on the hearing level of traffic personnel
Journal Title: Medpulse International Journal of Physiology - Year 2018, Vol 5, Issue 1
Abstract
Background: Noise is an important “stress factor” in the environment of people, nowadays. After age induced hearing loss (presbycusis), second most common type of sensorineural hearing loss is noise induced hearing loss (NIHL). Traffic personnel are one of the most vulnerable groups for NIHL. Material and Methods: 150 volunteered traffic personnel were studied for the effect of continuous exposure of noise on their hearing over a period of one year. Results: Noise induced hearing loss was observed in 22% subjects. Bilateral involvement was seen in 32%. Majority (69.69%) of the subjects had mild hearing loss. Noise induced hearing loss was more prevalent in subjects exposed to noise pollution for more than 3 years. Conclusion: Direct association was noticed between noise induced hearing loss and duration of exposure to noise. So, periodic checking of traffic policeman (clinically and audiologically) at frequent intervals of time is essential. Moreover hearing protective devices such as ear plugs and ear muffs should be provided to them during the duty hours.

Influence of digit ratio (2D:4D) on reaction time and athletic sprint performance: A short term pilot study
Digit Ratio is the ratio between the lengths of index finger to that of Ring finger. Recent evidence suggests that the relative length of the 2nd to 4th finger (2D: 4D ratio) is a biomarker for prenatal exposure to testo...
