KAISHEGNWEIAcoustic Foam Egg Crate Panel Studio Foam Wall Panel 48" X 24" X 2" (4 PACK, Black)

How well do these work with a 17x13' room converted into a garage gym to remove an echo and lower the noise of a deadlift onto a wood platform?

if i fill the full ceiling with these will they absorb sound from upstairs neighbors and also block my sound from going up?
