F1 supremo Bernie Ecclestone suggested he was unhappy with the noise of F1 cars in 2014 after the season-opening Australian Grand Prix, according to Sky Sports.
For fans watching on television, as our own columnist Matthew Walthert explored, noise levels don't make a huge difference to the viewing experience.
However, as the video above shows, it clearly does make a difference to fans in attendance.
An Australian Grand Prix user compared the sounds of the cars from the same spot at Albert Park in 2014 to their contemporaries in 2013.
F1 has changed over this year from 2.4-litre V8 engines down to 1.6-litre V6s with turbos.
The change has presented no shortage of challenges from an engineering perspective—the fact that people are now worrying about the sound they make is the icing on the cake.
