Hello. What is the best way to reduce echo in a closed room? Thanks in advance for help.

I now live in my country house, which is almost completely made of wood, I can say that at the moment a very strong echo is created due to the wooden floor, which not only makes the room seem empty and lifeless, but also, for example, when listening to conversations or music. we might not be as listenable, check here https://www.quiethome.life/how-to-re...-floored-room/ there might be a solution to this problem.
