Selective and Divided Attention: Extracting Information from Simultaneous Sound Sources.

摘要: The way in which sounds interact and interfere with each other (both acoustically perceptually) has an important influence on how well auditory display can convey information. While spatial separation of simultaneous sound sources been shown to be very effective when a listener must report the content one source ignore another (a condition known as selective attention), little is about influences performance divided-attention tasks, i.e., tasks more than source. This paper reports preliminary results from pilot study investigating perceived consistency locations selectiveand tasks. Results demonstrate that 1) both overall generally better are at different they same location; 2) randomly changing trial tends degrade compared conditions where fixed; 3) above effects larger for selective-attention dividedattention
