can one of you experts explain signal-to-noise ratios, like why exaclty peak levels are at -db, what about spl? I have a pretty good concept of them all, but no idea how they interconnect, or why they are really important. thanks!
Typically, SPL is measured by a sound meter after a signal has been amplified and played through a speaker and has no direct correlation to any level within the system other than louder and quieter .... dB's are used often to express a value while the signal is still an electrical impulse at line level although SPL is expressed in terms of dB's .. .
Signal to noise ratio is the difference between the noise floor, a systems self noise at idle, with the fader set a unity gain and the loudest sound the system is capable of reproducing at a specified distortion figure.
