Abstract
An acoustic lens is presented that redirects high frequency voice sounds over a barrier to improve the intelligibility of speech when a protective barrier is used to isolate people from each other. The acoustic lens includes curved sheets to delay sound to create focal points on each side of a barrier, where the focal points are lower than the top of the barrier.
