Ron:
The IVP screams like hell in the assent. It's a good sound. Power. Climb. Gross inefficiency. Major fuel burn. The all American way.
It chills out in cruse.
And gets even more quiet in the descent.
But the down side / disadvantage of all that quiet, is that you are not burning hardly any dinosaur juice at all. Which, depending on your political persuasion, is either good news or bad news.
Without adding more weight than your already overly heavy IVP can stand, you cannot quiet the IVP enough for climb-out.
Give up. Kind of like being married. You just deal with it.
You can't make your bird heavy enough and quiet enough to make it quiet on climb-out. You don't want to be that heavy.
It is a noisy frigging airplane. Again, kind of like being married. It's just noisy. Consider an investment in Noise Canceling Headset technology (I wear one around the house). Way cheaper than making the airplane quiet.

Hello guys
I am still doing training and getting the last bugs out of the plane here in Redmond, but one of the first things I like to do when I am back in Florida is getting the Garmin GTN750 and getting more sound Insulation as I think the cabin is kind of noisy.
Specially in climb it does. Funny enough it is the least noisy in descent……
Do you know of any good shops specialized in sound insulation? Thanks
