Hi Vgv Varma,
I dont know what you could measure... I think the airplane turbine! But There are few things that surpass..
I think is about 146/148 dbA
Trust me its very very loud!
Try to this! Bye man
Hi Vishnu, all sound level meter has about 3/5 db higher margin, so i think you whistle is about 140dbA.
Many people come to this measure.
Anyway the instrument is a Larson Davis 820 better is Larson Davis 831.
Best regards Luca
Very good! :D
If you set RANGE to 120, the meter measures sound levels from 110 to 126 dB. If the meter measures more than 126 dB in Range 120, the number 126 and the bar graph flash.(http://www.radioshack.com/graphics/uc/rsk/Support/ProductManuals/3302055PMEN.pdf).
BUT THEY WERE VERY GOOD!! CONGRATULATIONS!!
