Anthony -
As long as it's a question that you're wondering about the answer
for, just about anything can be a good project. It's even better if
your project involves a lot of different things for you to think about,
like this one does. For example, the project you described involves a
lot of different aspects of science - like the biology of how people
hear, the physics of how sound travels, and the engineering that is
used to build different kinds of walls.
When you do any experiment, it's important that you keep everything
the same except for one aspect (called the 'variable'). For example,
you could use the same wall, the same sound, and the same distance, but
do it with different people. Or, you could keep everything the same
except for changing the sound. Perhaps people can hear lower or higher
pitches through the wall better or worse. Or you could try keeping
everything the same except to do it across different types of walls -
like the inside vs. outside walls of a house, or the walls of your
parents' car.
Try thinking about it a little bit. There's lots of cool things
that you can do with it. Just pick the ones that you think are the most
interesting. And good luck!
