@mama cando a sound box is a box that covers the generator while still allowing air in and heat out. It is layers of materials meant to reduse and shatter sound harmonics. Inside layer is a perforated metal, it shatters sound waves and causes cancellation feed back, second is absorber a medium density house insulation like roc wool, third is a isolator a gap between first two layers and outside shell. You can repeat first two layers to increase efficency.. it can also be as simple as a wood box with insulation ( pink house stuff) around engine make sure you have air intakes and exhaust vents.
Plus this makes it consealable can look like more cupboard space or a planter if out side. This design when grounded can be a Faraday cage.
Running exhaust through water can cause issues if it causes too.much back pressure it can affect engine function.
Most small generators have exhaust pipes same size as motor cycles you can get used ones cheap.
