Hello, Bruce you said the efficiency is 1 E=3D1. I have read in a paper fr=
om montana univercity I think that the average efficiency is 0,65 or so. So=
I am using this number in my exell "Calculation parabolas 40,60,and100" Yo=
u can find this in Files. My parabolas are diy in hard and thick fiberglass=
.
In my paper I also have used the formulas from Sengaudio for Volume psicoa=
coustic, power sound intensity, and sound pressure voltage. Can you or some=
body recomend some alterations more realistic for my exell.
Regards,
Jose
