How do you use scaling factors?

I am trying to add custom boundary conditions to the built-in Pressure Acoustics (frequency domain) interface using weak contributions.

I see that the weak expressions in the pressure acoustics node contain a scaling factor equal to 1/omega^2.

I don't really understand the effect of including this scaling factor and don't know if I need to include it in the weak contributions that I want to add.

Can anyone shed some light on what the scaling factor is for and how to know when to use it, or point me in the direction of some references where I can learn more?

Thanks
