You cannot "measure" the subjective loudness feeling in decibel with a "dB"-meter. You can measure the objective sound pressure with a "sound pressure meter" that shows the sound pressure in pascals or the sound pressure level SPL in dB or dBA.

The amount of deflection of a membrane held taut, being bombarded by the sound wave, is one indication of the loudness. The ear drum is another sensor.
