Abstract
Noise is a form of environmental damage. An increase in the background noise leads to negative consequences for the mental and physical health of people. Noise is the greatest threat to those who by virtue of their profession are forced to constantly be exposed to it. The problem of increased noise levels in the workplaces of drivers of vehicles (buses and trams) in the cities of the Irkutsk agglomeration, as well as in sections of streets with installed noise screens (areas adjacent to linear sources of noise pollution and areas of sound shadow) is considered in the article. The legal framework for noise regulation in the Russian Federation is studied. With the help of a sound level meters, instrumental measurements of the noise level at workplaces and territories equipped with protective shields were made. The calculation of statistical characteristics and standard deviations of measuring instruments was carried out in the work. An analysis of the results obtained and their comparison with established sanitary standards for their excess were conducted.

Summary
Уровень шума на рабочих местах автотранспортных предприятий в городах Иркутск и Усолье Сибирское (Иркутская агломерация). В статье рассмотрена проблема повышенного уровня звукового давления на рабочих местах водителей автотранспортных средств (автобусов, трамваев) в городах Иркутской агломерации, а также на участках дорог с установленными шумозащитными экранами (зоны, примыкающие к линейным источникам шумового загрязнения, и зоны звуковой тени). В настоящее время для определения допустимого уровня шума на рабочих местах, в жилых помещениях, общественных зданиях и на территории жилой застройки в Российской Федерации применяются нормативно-правовые документы [1,2,3,4,5,6]. В соответствии с санитарными нормами [2] на рабочих местах сотрудников автотранспортных предприятий, максимальные уровни создаваемого шума не должны превышать 75 дБА в кабинах машинистов тепловозов, электровозов, поездов метрополитена, дизель-поездов и 60 дБА в кабинах легковых автомобилей и автобусов.
