Answer 1

It is called Acoustics, the result sound on or in a building.

The first thing would be to carpet the floor where the carpet's pile drags the sound waves as they pass and stops them reaching the walls to rebound, the echo.
The walls come next where metallic objects are removed and a fibrous spray to act like the carpet would be applied.
Here we stop and listen to the result as we might deaden or make lifeless the sound we have left.
Has it lost its lower frequencies, the bass?
If yes we take up some carpet.
Are the higher frequencies, the treble still bouncing around?
Perhaps we can add mobile screens to help.
All of the above take something out of the sound you hear but you have solved the problem of echo.
The rebounding sound of the pressure waves as they hit an object are echoes.
If you wish to go deeper into the subject, a Dr Angstrom made up a table showing how sound exists on a certain wavelength and where at the other end light has a portion of this table?
It's interesting to think that light and sound are related doesn't it?

I hope this increases your knowledge as well as helping you doing your homework. Learn the above and your homework will have been worthwhile.
Good luck.

Answer 2

dampen the sound. Either line walls with foam egg crate material or hang sheets of fabric. A lot of Symphony halls use angles and fabric to deaden the echo.

Answer 3

Use a duck to make the sound. A ducks quack has no echo.
Well actually it does. It is an urban legend that it does not.

I think you'd need some serious sound cancelling equipment to kill your echo.

Oh hang on. You could drape the walls with sound absorbing material. Foam or dense fabric. Or hang baffles from the ceiling.

Answer 4

One thing might be to carpet the hall to dampen any noise from creating an echo.

Answer 5

Create a vacuum in the room, no sound will travel.

To decorate a room, add carpets/ lots of furniture/ drapes on the walls etc to ''soak up the sound''

Answer 6

U can use soundproofing acoustic foam that absorbs echo, like in a studio.

Answer 7

Egg cartons lining the walls will absorb some of the sound and should be quite effective if unattractive.

Answer 8

Carpet the floor.
There's no sound in a vacuum but thats not much help, cause there's no air in a vacuum either.

Answer 9

turn into a duck. their quack doesn't echo and nobody really knows why but it's true. if that doesn't work I don't know.

Answer 10

Speak a lot quieter.
