Creating MP3's (week 1)

In our second lecture of our first week of class, we discussed creating MP3's, which is of great use to my invention. MP3's are compressed so that the frequencies of the sound are better heard by the human ear. WAV files are larger files with raw material, or uncompressed audio. The human brain cannot even hear all the different sounds of a WAV file. People can hear between 20Hz and 20kHz, so converting audio files from WAV files to MP3's is a great idea.

For my invention of the music earmuffs, I would have an MP3 player or ipod connected to the earmuffs. Customers could use their own MP3 device with their personal music and just connect it to the earmuffs. The earmuffs would only have MP3 sound because it's best for listening. CD's contain uncompressed audio, which is a waste since people can't hear all the extra frequencies in such sound, so it'd be of people's best interest to get these earmuffs and listen to MP3 players instead.
