Can a small inverter generator be made quiet enough that suburban neighbors won't hear it running?

After all the talk here about natural gas shortages and the issues in Texas last winter, I've been thinking about picking up my first generator. I know I will need an inverter so I can run sensitive electronics, I've been looking at some of the cheaper honda look-alikes in the 2000w range. I've also seen some of the cheaper open frame inverters with slightly more wattage (3000w - 3500w continuous) for just a few dollars more (around $50 to $100 more). My purchase is not intended as a total shtf prep, but rather for temporary outages lasting up to a few days. I would need to power a few comfort items: 2 fridges, gas furnace (if natural gas is available but power is out), maybe a tv or microwave. Both of these types of generators could probably handle each of these items, but the 2000w will not be able to power them all at once. While I would like to have a higher wattage unit, I think the benefits of a near silent generator would make it worth it, IF IT IS POSSIBLE.

So my question is this: is it possible to make a small 2000w inverter generator quiet enough that neighbors who are outside and 100 feet away won't be able to hear it running? Imagine it is the day after a winter storm, no cars are on the road, it is virtually silent outside. in my area no one has snow blowers so any small engine noise would be suspicious.

I know I would need to build a baffle box or quiet box to reduce the noise level of the generator. I briefly looked on youtube and found a few examples of people running inverters inside a quiet box. Most of them said it was quieter than a window A/C unit, but I think even that might be loud enough to be noticed. The only time I've ever been around a honda inverter was when I was walking around sporting events. I did notice that you can't hear them until you are nearly on top of them, but a sporting event is also much louder than a quiet neighborhood after a snow storm. If it is possible to quiet an inverter enough I may look further into it, but if it is definitely not possible I will probably look at the bigger but slightly louder open frame inverters.

I have an inverter generator, it is incredibly quiet when idling along. But as you put more load on it it begins to rev up. As it revs up it makes more noise. Even fully revved up it is quieter than a non inverter generator.

If the exhaust is pointing at you it is fairly loud even 50 feet away. If the exhaust is pointing away it is quieter and if there is something between you and it it becomes very quiet. However that doesn't mean neighbors wont hear it, it just means it will be fairly quiet. The quieter the neighborhood is the easier it will be to hear.

Often times in the evening when things get quiet and the wind stops blowing I can hear my neighbors gate opening and closing a half mile away and I can hear their their conversations but can't quite make out what they are saying. So at that time I would expect even the quietest generator would be heard by them.
