These days -- at least in my neck of the woods -- that's all anyone cares about. That will play a huge factor in someones purchase if they live near me.
I've made several referenced to camping. Noise is a major issue there along with weight. Noise is a very interesting topic.
Many inverter generators are 2 stroke (oil mix with gas is the way to tell), many are 4 stroke. Both types claim to be low noise, however the two stroke versions produce a much higher pitch that can be very annoying even if measured as quieter.
Lower noise with an inverter generator is often because they are used at far below rated output and the engine throttle down. An advantage of inverter generators is they can slow down under light loads without affecting the frequency or voltage output. Conventional generators need to operate at constant speed to maintain frequency. They can regulate voltage independent of speed.
Conventional generators can be made just as quiet. The manufacturers just need spend a couple extra dollars on the muffler.
My conventional Yamaha 5200 Watt generator is FAR less annoying than almost any 2 stroke 1000 Watt inverter generator! Yamaha just put a decent muffler on it.
