Some notes on analytical derived loudspeaker arrays with uniform radiation
characteristics are presented. The array coefficients are derived via analy
tical means and compared with so-called maximal flat sequences known from t
elecommunications and information theory. It appears that the newly derived
array, i.e., the quadratic phase array, has a higher efficiency than the B
essel array and a flatter response than the Barker array. The method discus
sed admits generalization to the design of arrays with desired nonuniform r
adiating characteristics. (C) 2000 Acoustical Society of America. [S0001-49
