There is a field dedicated to this called as psychoacoustics. Sound pressure level (SPL) alone won’t work for this experiment like you said. There are other metrics like steady state and transient noise, masking from different frequencies having different effects on humans. It is definitely doable but far more complicated than the tweets seem to make it sound.
