Un sistema de cavidades que comprende: una cavidad (2) con una abertura; y una estructura acústicamente reflectante (18, 20) ubicada al menos parcialmente dentro de la cavidad (2). Dicha estructura (18, 20) comprende una o más superficies acústicamente reflectantes (24, 26, 30, 32), cada una de las cuales es oblicua al plano de la abertura (27). Dichas superficies acústicamente reflectantes (24, 26, 30, 32) pueden estar dispuestas para reflejar las ondas acústicas incidentes fuera de la abertura, evitando la reflexión en una región (48) en o cerca de un borde delantero (14) de la cavidad (2).

    A cavity system, comprising: a cavity (2) comprising a cavity opening; and an acoustically reflective structure (18, 20) located at least partially within the cavity (2), the acoustically reflective structure (18, 20) comprising one or more acoustically reflective surfaces (24, 26, 30, 32), each acoustically reflective surface (24, 26, 30, 32) being oblique to a plane of the cavity opening (27). The one or more acoustically reflective surfaces (24, 26, 30, 32) may be arranged to reflect incident acoustic waves out of the cavity opening while avoiding reflection into a region (48) at or proximate to a leading edge (14) of the cavity (2).
