I start my calling on the soft side in case there's coyotes close by. Then I'll increase the volume after I've called for awhile, I never do blow real hard into my calls.
A coyote can hear a good distance, this will vary depending on the conditions and terrain.
One time I called one in and seen him come off a hill a mile north of me, he came on a dead run.
However when the wind shifted and blew my scent right in his face he left just as fast as came in.
