The sound of the A/C unit will partially interfere with outside sounds but, the turbulence of the air in the room tends to scatter other sounds as the air is disturbed, making sound waves more difficult to transmit to the ears.

The air conditioning fans generate a constant "white noise" sound. This sound is not perceived by ear but can be used to reduce noise levels of certain environments.

The ear tunes itself to give you a decent impression of the loudest noise around. If that noise is chatter from outside, you will notice the chatter from outside. If the aircon is luder, you will not hear the chatter from outside.
After a while, you get used to the aircon noise and ignore it. The ear, though, does not compensate by reattune itself to the outside chatter.
