Has anyone measured the noise level in the RV-7 cockpit in terms of dBA?

93~95 in cruise measured with iphone on my 7 Tip Up with no sidewall or firewall insulation

Based on the responses, ~100dBA seems. I wonder how that compares to a C172 or C152? Would be nice if it was lower than those two.
I used to fly an Arrow with the same engine that I have in my RV 7. I could hear my watch ticking in that airplane.
I'm curious to know what the Arrow has in terms of mechanical and acoustic isolation that might also be feasible to install in the RV-7.
I tried to reply to your question but got timed out. I'll get back later. I had to log back in just to write this so I going to bed.
Holy cow, FL-mike, you win the thread. Excellent data. What is the significance of most of the energy being at the prop frequency? My guess is that it prop noise would be acoustic noise, penetrating through the drum-head firewall and also beating down on the canopy.
