Um novo método de projetar um conjunto de microfones com duas saídas preservando informações binaural é proposto neste artigo. Este sistema emprega beamforming adaptativo usando múltiplas restrições. As dicas binaurais podem ser preservadas nas duas saídas pelo uso dessas múltiplas restrições, com formação de feixe simultânea para aprimorar os sinais alvo também está disponível. Uma simulação de computador foi conduzida para examinar o desempenho da formação de feixe. Os resultados mostraram que o array proposto pode realizar tanto a geração de sinais binaurais quanto a formação de feixe conforme pretendido. Em particular, beamforming com restrições duplas apresenta o melhor desempenho; DI está em torno de 7 dB e boas diferenças de tempo/fase intercanal (interaural) e de nível são geradas dentro de uma região alvo na frente. Com restrições triplas, entretanto, o desempenho da formação de feixe torna-se pior, enquanto a informação binaural é melhor percebida. A definição das respostas desejadas para fornecer informações binaural adequadas parece tornar-se crítica à medida que o número de restrições aumenta.

Abstract: A new method of designing a microphone array with two outputs preserving binaural information is proposed in this paper. This system employs adaptive beamforming using multiple constraints. The binaural cues may be preserved in the two outputs by use of these multiple constraints with simultaneous beamforming to enhance target signals is also available. A computer simulation was conducted to examine the performance of the beamforming. The results showed that the proposed array can perform both the generation of the binaural cues and the beamforming as intended. In particular, beamforming with double-constraints exhibits the best performance; DI is around 7 dB and good interchannel (interaural) time/phase and level differences are generated within a target region in front. With triple-constraints, however, the performance of the beamforming becomes poorer while the binaural information is better realized. Setting of the desired responses to give proper binaural information seems to become critical as the number of the constraints increases.
