Thus, the Tycho impactor, probably 8 to 10 km wide, came in low over the Moon's western horizon. On Earth, 109 million years ago, dinosaurs and other reptiles must have witnessed this devastating collision and perhaps suffered a few days later when fist-sized pieces of Tycho ejecta hit the Earth.

Hi, Nic One Ear, I have tinnitus in only one ear (the right ear). I've had it for many years, and it was mild until I took a blood pressure drug for the first time. That was four years ago, and I've been working to manage my increased tinnitus ever since. I have hearing loss in that ear, too.
