Students are much more open when anonymous

How much does the sound pressure level increase when the sound pressure doubles?
If we have two sources of a sound with 40 dB SPL level each, what is the total level of the sound?
A sound pressure level of a 1000 Hz tone is 40 dB SPL. How much it is in dB HL and dBA. Explain.
A sound pressure level of a 2000 Hz tone is 50 dB SPL. How much it is in dB HL and dBA. Explain.
What does it mean that the sound level is -20 dB SPL?
Informing students that this kind of questions may be on the exam
