The article presents the results of scientific research on the assessment of the acoustic characteristics of the interstate highway of the Central Caucasus, passing through the mountainous territory of the Republic of North Ossetia Alania in the residential area where the miners of the Sadon Lead-Zinc Plant live. A schematic diagram of the highway in the zone is shown, and a design diagram is given to determine the acoustic parameters of the impact of traffic noise on the habitat of the resident population. On the basis of the studies performed, the most effective design parameters of the acoustic shield are set, providing sanitary permissible sound pressure levels in apartments without additional sound insulation and in the zone of influence of roadside noise in the settlement at the maximum intensity of the traffic flow along the road. Recommendations on the effective operation of the acoustic shield and the method for estimating the noise factor in the mountain zone with a highly dissected relief are given.
