The article substantiates methodological approaches to organizing the control of acoustic load from
railway transport in adjacent areas. A comparative analysis of regulatory documents from Russia and
Uzbekistan governing noise measurements (GOST 23337-2014, MUK 4.3.3722-21, SN RUz 001-95,
SanPiN No. 0376-16) was conducted. Particular attention is paid to the methodology of GOST 20444-
2014 and its analogue UzKS 20444:2015, which involve a series of measurements by type of rolling
stock with subsequent conversion of equivalent sound levels for different time intervals (Lnight, Lday,
Lden). A practical example shows that applying this approach yields more accurate results (7–10 dBA
lower compared to direct measurements) that align with WHO recommendations. Ways to unify noise
control methods are proposed, including creating a database of acoustic characteristics of rolling stock
and updating regulatory documents for the calculated determination of Lnight, Lday, Lden indicators.
