I'm just wondering why do empty houses have echoes but when its filled with appliances and stuff it doesn't echo anymore. It's pretty obvious but I just want to make sure.

Sound bounces off hard surfaces better than it does soft surfaces.
If you put drapes, carpets and other soft things into a room they will absorb a lot of the sound.

it's because echoe is a bouncing of a voice.So if there's no appliances the the voice go straight to the walls and goes back to you whereas if there are appliances some of energy of the voice will strike to the appliances and goes to different direction not back to you

All of that 'stuff' takes up space, so there are not any 'flat walls' to echo back the noises as well. The 'echoes' are still there, but they're quieter because the 'space' that reflects them is more 'broken up' ...

Hi. Bare walls and floors reflect sound in phase which strengthens the sound. Additional items like refrigerators and furniture both add additional out of phase echoes and absorb sound. Sound right?

in empty house the sound takes longer to strike with walls and reaches with delay to our ears whereas if u stuff ur house it came back to u quickly after striking the appliances as they are nearer to u.
