Abstract
The feeding of loudspeaker arrays by special sequences, or codes, with the purpose of obtaining isotropic radiation intensity patterns is considered in this paper. In particular, new codes of the Huffman codes type, which are generated by combination of Barker codes, are considered. This type of feeding is shown to result in almost isotropic patterns which are superior to those obtained by feeding the arrays with Barker codes, as suggested by previous investigations. The present work has direct applications in special public address systems and underwater acoustical arrays.
