It is very important for auto24ring to take care of the noise coming from the racetrack. For that reason we have created additional noise walls in size of 5000m3. And for the same reason there is a change in noise regulation in the static test max level. The maximum noise level in previous regulation was 108dB(A), but for coming season it is 105dB(A). There are no changes in measuring methods nor engine rpm-s while carrying out the test. We ask kind understandig from our clients as the change in regulation is based on our wish to make the environment around the racetrack better. More detailed noise regulation available in our website.
