1. The problem statement, all variables and given/known data A jackhammer emits sound at a decibel level of 130 dB. The wavelength of the sound is 1.0 m. What is the linear sound intensity? What is the pressure amplitude? What is the displacement amplitude? 2. Relevant equations Beta = 10 log (I / Io) ...and??????????? 3. The attempt at a solution Solved for question 1, the linear sound intensity, and received an answer of 10 Watts/meter. I combed my physics text and have not found an equation that wil provide me with either the pressure or displacement amplitude based upon the information I am given. I found a lengthy equation using density, angular velocity, and some variable "s naught" among other variables, and I simply don't have this information or have little means of finding it. Could someone please just help me find the right equations??????? Thank you!
