F fedail New Member Apr 13, 2009 #1 Hello all, i want to measure the voice level and loud i found some topics on web talking about the sound pressure and more noisy calculation thats when we talk on paper but if we talk on hardware we have to talk on frequency and voltage . so can any body help me with this problem ?

F fedail New Member Apr 15, 2009 #5 yes this one to measure the amplitude but also i need to measure the frequency and pressure you know how we can recognize the sound is it woman or man by frequency and the laudy by amplitude and the pressure by what ? i am still trying to find the solution

For that you will need a computer and some sophisticated sound analysis software.
