Hondas Getting Louder
We have two Honda EU2000 generators. Normally we run them alternately unless the AC is needed. So each one has about 400 hours. DW says they are louder than when new — confirmed by a db meter check...

One tech firm tested a number of the iPhone apps against very sophisticated meters. They found only the SPLnFFT app to be accurate. In fact, that app was reported routinely as accurate as a very expensive meter. But in all of this discussion, the suggestion to measure my Hondas against a new one is the only reasonable approach. The actual decibel count is not the issue. It's the change that matters. The "Noise and Directivity" test would also provide a reference point. IMHO, I would guess that the muffler packing deteriorates with run time.
