Is there a math formula to calculate the difference of dB of sound, in different pure transmitting mediums?
For example, based on a measurable decibel level, with a known frequency, a known atomic weight of say, oxygen or hydrogen, a known volume of transmitting medium.
Two unlabeled boxes the same size, one with oxygen the other hydrogen, I send a sound wave through each box, measure the dB and then be able to tell which box has Oxygen from the resulting dB level. Is there a formula? PS With a formula I may be able to predict what the dB level may be.
