Science Buddies: "Ask an Expert"

These questions reguard my science project.
Every student must've devoped 10 questions for an expert in my class.
Reply quickly! Thank you.
1. What are frequencies?

2. What is bit rate?

3. What is a WAV file?

4. How does the musical compression of the MP3 work?

5. Why is the MP3 useful?

6. Why was the MP3 developed?

7. Can the human ear detect the difference between a CD and MP3 version of a song?

8. Who came up with the idea for the current MP3's we use today?

9. Is there a hearing damage risk by listening to digital audio players?

10. What is tinnitus, can digital music cause it, is it the only cause of tinnitus?

Thanks again.

tgcogs,

I would suggest you copy/paste each question (one at a time) into the google search bar and see what comes up. I suspect you will very quickly find your answers.

Good luck!

I am very grateful for the help. But, I strongly need these questions answered by sciencebuddies.org preferably by an expert in the field! I understand this may take time but it is greatly appriciated and required! These questions were not becuse I was having trouble, but a class requirement! Please help in a suitable amout of time! Thanks, again!

tgcogs,

The experts are not expected to provide the answers for you. We are here to help you figure things out. Please ask your teacher to post here explaining why he or she requires us to answer these questions for you.

I suggest you search the Science Buddies site for past posts related to the MP3 Squeeze project. The bibliography on the project page will lead you to the answers, such as
