Love it when people make a claim and post a PDF like it's evidence.
From your PDF:
"The steady speed results of the Nissan Leaf and the Golf variant and the polynomial trend lines are shown in Figure 8. For all the measurements speeds the Leaf [EV] emits less noise than the Golf [ICE]."
This is measuring 10kph to 70kph.
Also these are small European vehicles compared to other small European vehicles. You won't see those so much in a downtown US city.
Consider that the volume in US cities is from the noisiest cars. It doesn't matter if the average car is just as quiet as an EV - it matters what the average total noise is, and that depends on a few loud cars. Likewise pollution. One "rolling coal" fuckwit is all it takes.
- Dah00n 3y agoI'm sorry you don't agree with a conclusion that is based on facts just because your country is different. Still the facts are facts. At 50km/h -city limit in most of EU- EVs are louder. I'm pro EVs so please stop reading things into what I said that I didn't actually say. I specifically said the problem is the tyres.
- lowbloodsugar 3y agoYou are responding to an article about EVs in the USA with data for Europe. But lets stick with Europe and your PDF. You have cherry picked the exact one place where "EVs" are "louder". Specifically you picked: 1. A commercial EV van. 2. Traveling at 50km/h. 3. At a steady state. In every other measurement, the EVs were quieter: 1. The passenger EV is always quieter. 2. The commercial EV is quieter at any other speed. 3. Both EVs are quieter at anything other than steady state, i.e accelerating or decelerating. My experiences of European towns and cities are that cars stop and go a lot. In pedestrian areas or residential areas are often limited to below 50km/h. And again, I remind you that these vehicles were themselves cherry picked and are not representative of vehicles on the road in the USA or Europe. My mum drives a diesel passenger car and it is assuredly not quieter than any EV even when it's not moving - and that's a car that is in good working order. And even then, the conclusion from this paper is: "In urban areas where the speed it often above 30 km/h the introduction of EV’s will not have a great influence on the traffic noise."
