On April 29, in the "Latvian Railway" training center in Riga (Dzirnavu Street 147/3) an ISRNM project event took place dedicated to the International Noise Awareness Day.

It was the first time when the general public had the opportunity to see and learn about ISRNM developed anti-noise wall fragment what is created from composite materials blocks.

One of ISRNM project aims is the EU rail noise applied method RMR adaptation for the 1520 mm gauge railway. The project activity B2 - RMR method adaptation and improvement  will be worked out by specialists from  RTU Institute of Railway Transport. In June 2014 they completed the theoretical part of the RMR method analysis and compiled the next steps of experimental research plan.
