Traffic Police


In the modern times we live in noise pollution is all pervading. SAHI under took a study on the effects of noise pollution on Traffic Policemen, who are one of the most vulnerable  groups exposed to this problem. To our surprise 76% of those screened had audiological evidence of Noise Induced Hearing Loss (NIHL). Traffic Policemen who had completed 5 years tenure on the streets had 100% incidence of hearing loss. A small percentage of policemen had hearing loss due to other problems for which surgeries (04), medication and hearing aids (01) were prescribed and carried out. SAHI also gave counseling to Policemen and recommended the police department on possible preventive and contingency measures.

Screening of hearing test for traffic police men is carried out in Apollo Hospital on the International Deaf Day during the month of Sep 2010. Traffic police are at the risk of highest grade of sound pollution. 52 traffic police men varying 6 months to 8-10 years of experience were screened for hearing loss. 63.5% of traffic police men found to be suffering by irreversible hearing loss (Sensorineural hearing loss) in the high frequency due to the exposure of high decibel level of sound pollution. Up to 30% of affected traffic police men were having average of 4 years of experience which is conclusive of the risk of hearing loss which is directly proportional to the duration of exposure.

Auto Drivers

A free medical camp on auto drivers was conducted under the auspicious of SAHI & Sri Satya Sai Seva Trust on 11.11.09 and also on 22.08.10. The aim of these camps was to evaluate hearing problems of auto drivers who are at higher risk of sound pollution. The average time they are exposed to noise pollution vary from 4 to 10 hours per day.
The two camps evaluating about 60 auto drivers being in the job from 1 year to more than 16 years. The evaluation is done by history, examination and Puretone Audiometry. The results shown that, there is high incidence of sensorineural deafness in high frequencies which is directly proportion to numbers of years in the profession.
The following table clearly indicates the incidence of sensorineural nerve deafness.

No. of years of experience
16 and above
11 to 15
6 to 10
0 to 5

From the above chart it is clearly evident that incidence of sensorineural deafness is increasing with amount of exposure i.e. years of auto driving. Since sensorineural deafness is a permanent disability without a cure, prevention should be high lighted. With more awareness about sound pollution the incidence of this problem can be checked.
