Yes, and that power close to the suppressed carrier is all wasted 
low-frequency transmitter power. About 3 dB!

Yes, and with some mics, how close it is to our mouth. Directional mics, 
called a "cardioid" because of the shape of their pattern, emphasize 
bass when very close to the source. Virtually mics for live musical 
performance have this characteristic.

Yep.
