This Generator Quiet Box has a SECRET!

This is no ordinary quiet box, specially built for a fairly large 7kW petrol generator. The inside features Helmholtz Absorber Panels to help reduce the noise and specific frequencies that the generator produces. The result is very effective at damping the noise, and I can stand right next to it and have a normal conversation with someone without shouting or even raising my voice even slightly. I asked my neighbours if they could hear it, and they said they did not even know that I had a generator!
