The major source of noise in major cities are motorized road vehicles; it is responsible for creating annoyance among people.

The main objective of this study is to evaluate and analyze road traffic noise in Al-Hilla City-Iraq.

Digital sound level meters with frequency weighting networks were used in this study.

All measurements were taken on an A weighting frequency network, at a height of about (110-120) cm from ground and on fast range time weighting.

Noise levels have been measured at 48 major locations of the city from 7.00 am to 7.00 am in the next day at the working days.

It is observed that at all the locations the level of noise remains far above the acceptable limit for all the examined time period.

A safe distance between 60-75m seems to be suitable for all roads, except the Sixty-Street main road.

The noise perception survey indicated that 88% of respondents were not satisfied about the noise level in their place and 24% of them suffered from health problems related with noise pollution.
