  text: The appliance of time-reversal acoustics to classical trans-ducer design,
    medical, technical or audible range applica-tions brings forward new ideas whenever
    we need both, focusing acoustical energy in time and space. Unfortunately, the
    spatiotemporal focusing is limited through the amount of applied transducer elements
    as well as the ergodicity and randomness of the cavity [1]. This paper will show
    how the simulated annealing technique, a multi-objec¬tive optimiza-tion algorithm
    [2], is used to increase the nar¬rowness of the refocused spot by breaking up
    randomness for the benefit of ergodicity in a predetermined cavity.
