The video that everyone has been waiting for a long time. Test of a set for noise insulation of tires "Quiet tires" from the company Shumoff with MEASUREMENTS before/after.
I made noise insulation of tires on the Audi A4, in the B8 body. Tires: Nokian Hakka Blue 225/50 R17.
A lot of time was spent on this video because on the first day, when I planned to take measurements, there was a stormy wind and the measurements had to be postponed.
On the second day, in the morning, we managed to make correct measurements (on an empty road with two different types of pavement at speeds from 80 to 130 km / h.) and make noise tires. But the measurements that were carried out in the evening, after the noise insulation, were not accurate, because there was a dense traffic flow on the same section of the road and the sound meter showed exactly the same values as before the noise insulation, besides it started to rain a little.
And only after another day it turned out to make more or less accurate measurements after the noise insulation of the tires, on the same section of the road, at the same time, at the same speed. But I had to do five laps to get to the moment when there were no other cars on the road.
The measurements were carried out as follows: the car was moving at a certain speed for 10-15 seconds, after which I took the minimum and maximum values of the noise meter and calculated the average value. Thus, the noise level in dB was obtained at a certain speed and road section. Then, measurements were carried out in the same way after noise insulation. And the average values before and after tire noise insulation were compared.
The video was shot on DJI Pocket 2. 1080p 60fps.
