Abstract

An audio-visual arrangement, more particularly, a multi-media terminal, includes a picture screen on which pictures can be displayed. The arrangement further includes a plurality of electro-acoustic converters for reproducing sound that corresponds to audio information generated by the audio signal source. The converters are positioned at regular mutual distances along one side of the picture screen. The ratio of the strength of the control signals applied to the converters has values for which a sound wave concentration is obtained in a listening/viewing area situated dead opposite to the picture screen. With the audio-visual arrangement the nuisance of noise experienced in a living space and/or working space by persons other than the user of the arrangement remains limited. A further reduction of the nuisance can be obtained by a system in which the audio-visual arrangement is combined with means for active noise abatement.
