Early in life (18-35 y/o), I could hear it 80-100 yards with leaf off and minimal to no wind. Killed a bunch of drumming birds as they snuck in and oftentimes flanked me just below the crest of a ridge/slope. Nowadays, if I I hear it, he is within range and I am scanning every direction to try and find him before he finds me. If you try to learn and listen to it on YouTube videos, do yourself a favor, and use some quality headphones and you will be more apt to hear it than coming out of phone/laptop speakers.
