Abstract
The partition system disclosed herein incorporates apparatus for generating a speech masking acoustic field. Respective speakers are mounted near the bottom of each of a plurality of partition panel segments defining each work space and are aimed horizontally. These speakers are driven by respective signals which are subjectively incoherent as to frequencies of interest in the masking spectrum, thereby to provide a sound field without perceptible discontinuities.
