Dropping Weights and Shock

I built a platform with the 2 layers of particle board and 1 layer stall mat. My plates which hit the platform are also all bumpers. Even so, was deadlifting today with only 365 and the shock shook one of the smoke detectors off the ceiling in an adjacent room. This is in the basement on a concrete floor.

Granted, the smoke detector was most likely already loose but for the shock to reach the ceiling in the other room worries me somewhat. I don't care about the noise, it's the amount of shock that I'm wondering about. There are thousands of dollars worth of server computers in the basement as well which I'm very worried about possibly damaging.

Your servers should be on vibration dampers to start - deadlifting or not. That also might not be the most appropriate place to store them if you're deadlifting in the same room.

I've heard Rip say among other things about one's manhood, that dropping the bar on a deadlift is disrespectful to the equipment and the gym.

He never said he dropped the bar during the deadlift.

Edit: I guess it's implied in the subject line.

It’s a lot of weight hitting a solid object with a lot of force. Things are going to shake.

I remember one session with my girlfriend, there happened to be the rare gym lifter who was actually doing fairly heavy deadlifts. She was getting unnerved by the weight hitting the floor quite loudly after each rep the guy did, and I explained, "look, there's something like 500 pounds on that bar, there's just no setting that down gently no matter how hard you try."
