1. The problem statement, all variables and given/known data How does the sound energy level produced by woodwind instruments (a piccolo, a clarinet, and a bassoon) compare to the sound energy level produced by string instruments (a violin, a cello, and a double bass) and brass instruments (a trumpet, a trombone, and a tuba)? I am doing a group 4 IB physics project in which I attempt to answer the above question. I need a straightforward, quick response that will give me an equation to calculate the energy present in the different waves. I am using a scope that will allow me to determine the frequency, amplitude, speed, and wavelength of each instruments wave and I need to somehow relate the energy present in the wave to the data I am able to collect. 2. Relevant equations I know that E=1/2kA^2 but my problem with this equation is that I am not sure how I would determine what the value of k is for each wave. 3. The attempt at a solution As mentioned above, I have tried to look into the E=1/2kA^2 equation but am having difficulty with the value of k. I have searched in every spot I could think of to help with this and have returned empty handed. Any guidance in the correct direction would be appreciated.
