For example, I have a matrix of 3mm, which contains 25 grid points. Their colleagues send this signal:<br /> source_strength = 1e6; % [Pa]<br /> tone_burst_freq = 1e6 ; % [Hz]<br /> tone_burst_cycles = 5;<br /> signal_offsets=50;<br /> input_signal = source_strength*toneBurst(1/kgrid.dt, tone_burst_freq, tone_burst_cycles,'Plot', true,'SignalLength',kgrid.Nt,'SignalOffset', signal_offsets);<br /> Somebody tell me how much sound power is needed on this array? </p>
