The apparatus further comprises a housing 50 for the transducer element and nonÂporous structure, wherein the housing has a hole 51 through which wind and sound from outside the housing can enter the housing and the non-porous structure is arranged to cause a pressure differential in the housing and allow sound to be received through the input port of the at least one transducer element. The wind noise reduction apparatus may be applied to an earphone arrangement (figs 16 & 17).</p> |
