Claims (1)

  1. Согласно изобретению несколько микрофонов М1, М3 расположены фактически в одной и той же плоскости Р симметрично по отношению к оси D симметрии, перпендикулярной к этой плоскости Р. Между выходными сигналами разных микрофонов М1, М3 вводится сдвиг по фазе и сигналы, сдвинутые по фазе, суммируют таким образом, чтобы по существу подавить сигналы, соответствующие любой звуковой волне, приходящей на каждый из микрофонов М1, М3 в одной фазе и с одной и той же интенсивностью. Кроме того, устройство согласно изобретению может быть оснащено громкоговорителем 4, размещенным на оси D симметрии и сориентированным по этой оси в направлении, противоположном от микрофонов М1, М3. Применяется главным образом с системой конференц-связи.
