Example of Interaction Effects in Transducer Arrays.
Abstract
There have been various calculations of acoustic interaction effects in transducer arrays and at least one experimental study specifically aimed at exploring such effects. Of necessity, all this work considers special cases and provides little in the way of general guide lines which are useful for practical array problems. We shall present here some calculations which, although still in the special case category, cover a wide range of certain variables in an attempt to gain some insight into such problems. For example, the extent to which the transducer velocities in the array will vary when all transducers are driven by the same force is shown as a function of transducer spacing and individual transducer efficiency. The discussion is directed mainly at the case where the transducers are velocity limited, and the resulting limitations on radiated power are illustrated.
