I'm in my first year of engineering, and I have a project that involves the
scrambling of data using sound.
The set up is as follows:
-input a 4 digit number into a computer
-the computer scrambles the number using matrix algebra
-each number from the matrix has an associated sound to it (for a maximum of
-the sound will be send through water via a submerged speaker
-the sound will be received via a submerged microphone
now here is where I'm stuck. I need to know what effects water has on
sound. I know for sure that the velocity changes. But in order to continue
my project, I have to be able to calculate what the original source sound
Would the sound change frequency?
Anyways, once received and re-calculated, the sound would be reassigned to
its number between 1-18 and be put back through the inverse matrix to
retrieve the original 4 digit code.
Thank you for any help
