On an organ, the length of the pipe obviously determines the frequency. If you play a pitch on an "8-foot" pipe, it is a designation that means that you are actually playing the note you are playing on the keyboard or pedalboard. When you play middle C, you hear middle C. The lowest note on the keyboard and pedalboard are C with a pitch of 64 Hz when the 8-foot pipe setting is used.
A 16-foot pipe designation is one octave lower than the note you actually play. The bottom C on the keyboard and pedalboard are reduced by one ocatve and now play 32Hz.
The 32-foot pipe designation plays a note two ocatves lower than the actual note played. You won't find a 32-foot setting on any organ keyboard that I am aware of, but you will find it on some of the pedalboards (but not a Hammond). The low C on the pedalboard with a 32-foot setting is 16 Hz.
