Mods please feel free to move this thread to the correct section as I don't know where to post this.
My friend bought a DB reader from Maplins,this one: Mini Sound Level Meter : Enviroment Testers : Maplin it's Frequency weighting is C instead of A.
When we did a sound test on his EP2 with a Buddyclub pro spec 3 with the bung in it read 115 db, when I tested it on my ek9 with a Mugen Twinloop it reads 107 db. Both were done when it was warmed up. Does anyone know what those figures will show if the frequency weighting is A instead?
I know that if my Twinloop did a 107db then I wouldn't of been allowed on at Brands. The tester said it sounded quiet compared to the other cars and passed it.
I have googled about and seen graphs where the C weighting starts higher than the A weighting. Does anyone know what the difference is?
Thanks
Andy
