Intensity level at central maximum with two sound sources

[Sanosuke Sagara]

Here's some information :

Two same sound sources of equal amplitude, and the intensity level at central maximum is 50dB ,how much intensity level at this point when one source is present ?


What does it meant by intensity level at the central maximum ? Can somebody explain to me ?

First off,
do read the textbook because its important that u understand what the central maximum is...

You may know that Young's expt produces alternate dark and bright bands and there is one central bright spot ... this is called the central maximum

Do u know the intensity equation for a double slit experiment ?
This question is almost directly answered with a single equation!
