<p>An acoustic detector provides a planar arrangement of microphones. A windshield is arranged over the microphones, with a view to reducing the impact of environmental effects. A void is therefore defined over the microphones, and the 5 interior surface of the windshield, which defines the void, is shaped suitably to reduce the potential for acoustic waves propagating within the void to reflect back onto the microphones. 7143724_1 (GHMatters) P101664.AU LYNT . - ©1 CoL</p> |
