### Practical limitations
In an ideal world the signal applied to the physical transducer should give the same signal in air pressure. That is however not the case. For every transducer there is a significant random phase shift present. This will completely negate our effort to acheive a phased array. So we have to measure the phase shift of every transducer and incorporate this into the phase calculations.
