As I remember it, in a low pass filter, as the frequency increases, there's a 3dB point when the gain of the circuit starts to fall. Then there's the rate at which the gain falls, which is called the "roll off" which is so many dB per octave (50, 100 Hz is an octave - double the frequency) or per decade (50 to 500Hz is a decade, ten times the frequency). This filter is a FIRST ORDER filter, and there's only one roll off rate with frequency. There are SECOND and higher order filters, and things get messy fairly quickly, because there's a possibility of oscillations and resonances occurring with higher order filters. Their advantage is that the roll off gets steeper, basically a sharper response.
