Are smaller engines louder?
In terms of engines, this means doing more with less. But engineers have encountered a new problem to deal with in smaller engines: noise, vibration and harshness (NVH). As a result, and contrary to expectations, a small, fuel-sipping engine can actually be noisier and more vibratory than a large gas-guzzling engine.
