A case for an audio-visual recording instrument such as a digital camera includes an access opening 7, an image window 16 and a sound aperture 25 arranged such that the sound aperture is aligned with the sound pick-up. The sound aperture is covered by a porous wind reduction shield 27 which preferably incorporates a foraminous backing carrying a cluster of fur-like fibres arranged in a semi-coherent layer with their inner ends secured to the backing and their outer ends projecting from the case.
