    Can't anybody make up their mind on this traffic/car noise subject?
    First they said EV's/Hybrids are too quite and pose a threat to pedestrians. Then you read that traffic noise is linked to a greater risk of heart attacks.
    This is beginning to sound like all the other BS about one day coffee is bad for you then next week you read that coffee is good for you.
    It's no wonder more people are on some sort of mood stabilizer drug.....arrrrrrrrrgh!

    Another natural experiment, about which little, if anything, can be determined. These are uncontrolled "experiments" in which the researchers are basically trying to guess relationships and using correlational metrics to do so. Unfortunately, it should be obvious to even the most casual observer that regions that differ in level of traffic noise differ in a great many other ways - hustle bustle atmosphere, etc. This study is so primitive
    that it's a shame that someone had to pay to carry it out.
