Hi,
I have a quesion on sound terminology. When we talk about loudness of sound,are the terms 'sound intensity level' and 'sound pressure level' the same? Are these two terms indicate the loudness of sound?
My tutorial asks to write the formula for measuring sound?? I know the formula for measuring the sound level or loudeness of the sound which is
dB = 10 log 10 (I/Io) = 20 log 10 (P/Po). But measureing sound?
Thanks for any explanations...

Following is the question in my tutorial:
The loudness of sound is based on intensity level measured in decibels using a logarithmic scale and is relative to (a ratio of) the weakest sound the ear can hear
Write the formula for measuring sound
