  1. Matlab/Octave/FreeMat: Powerful Tools for Engineering Analysis BJ Furman 02DEC2012

  2. The lowest perceptible sound level of the human ear varies with frequency At what frequency is the ear most sensitive?

  3. What is the Matlab code to produce the plot?

  4. The SPL at 2.5 kHzcan be found with the interpolation function interp1()

  5. Cubic and spline interpolation is often used to smooth data

  6. The spline interpolated data gives a closer approximation to the frequency at maximum sensitivity

  7. We can make a better estimate of the maximum sensitivity using the interpolated data

  8. Matlab can play sound at Hz_min
