Long-term exposure to road traffic noise was significantly associated with increased CVD and all-cause mortality. Our findings suggest that studies that do not consider noise exposure may overestimate the cardiovascular burden attributed to air pollution. (Impact of Lifetime Exposure to Air and Nois …
Yes and no. A 14.9db increase of 85db background noise is big, while a 14.9db increase of 40db background noise certainly is not.
Decibels is logarithmic and there is little information in this study about environmental ambiance.
One graph starts at 40db, which indicates data was collected at roughly the noise level of a refrigerator. A casual conversation would roughly qualify as “noise.”
14.9dB is a BIG increase.

Yeah I was going to put the background reference in but the study didn’t have it. I feel that’s important.
