Abstract
A microphone assembly can include a microphone capsule having a diaphragm and a diaphragm cover, a grill for protecting the microphone capsule, and a filter material placed between the grill and the diaphragm cover. The microphone assembly can include a first air gap between the grill and the filter material to create a first interface, a second air gap between the filter material and the diaphragm cover to create a second interface, and a third air gap between the diaphragm cover and a diaphragm to create a third interface. The first interface, the second interface, and the third interface are each configured to create turbulence to assist in draining off energy from plosives and wind and reduce intensity of disturbances at the diaphragm. The filter material may include a mesh and can be supported by a frame, and the frame may be configured to fit underneath the grill.
