Title:
METHODS AND APPARATUS FOR IMPROVING SOUND WITHIN AN ACOUSTICAL BOUNDARY LAYER
Document Type and Number:
WIPO Patent Application WO/2019/040108
Kind Code:
A3
Abstract:
Wavy riblets are disposed at one or more auditorily important acoustical boundary layers of a sound producing device. Wavy riblets can be deployed directly onto the surface of the device, and/or onto a film or other carrier that is then positioned in or on the device. Wavy riblets can be advantageously deployed in sets, in a herringbone pattern, and sets of smaller riblets can be disposed between sets of larger riblets. Wavy riblets can also be superimposed onto other wavy or non-wavy riblets. Contemplated sound producing devices include speakers, musical instruments, fan blades and ducts.
