   Hi everyone,
   I would like to ask how the sound power and sound pressure are converted in KWAVE. For example, I have a matrix of 3mm, which contains 25 grid points. Their colleagues send this signal:
   source_strength = 1e6; % [Pa]
   tone_burst_freq = 1e6 ; % [Hz]
   tone_burst_cycles = 5;
   signal_offsets=50;
   input_signal = source_strength*toneBurst(1/kgrid.dt, tone_burst_freq, tone_burst_cycles,'Plot', true,'SignalLength',kgrid.Nt,'SignalOffset', signal_offsets);
   Somebody tell me how much sound power is needed on this array?

   Hi jackYANG,

   You could approximate the power by first calculating the average acoustic intensity (e.g., using a plane wave relationship) and then multiplying by the area of the source.
