Hi - Enjoying the Picanto, but road noise on rough surfaces with the low profile tyres seem bit high.
I tried checking with various phone apps, but they measure db decibels and not the normal db(A) decibels as "A" weighting is closest to human hearing and is the industry norm.
So bought a small meter and run some tests today to establish a base.
I will then try various sound deadening mats etc and see what results. if any I get in future-
Readings below- up to 77 db(A) sounds comfortable, but above that noise is irritating. AirCon and fan was running as it is hot here in Australia at present.
