a Power vs Volume Question


Hell,

I just replaced my old 200w power amplifier with a new 300w amp. by my surprise, with all things left the same, including the volume setting, the output read by my spl meter was the same between the two amps. isn't the 300w amp supposed to be louder at the same volume setting?

please post your thoughts.
thank you

Pawlowski, the decibel is a logarithmic function, not a linear one. Each doubling of power increases loudness by 6 db. The ear perceives a 10 db increase in sound level as a doubling of volume.

A jet plane taking off is around 130 db. A rocket launch close hand is around 180 db.
