Abstract
A microphone assembly including two microphones is usable in connection with a mask of the type worn by someone wearing a protective mask or respirator. The two microphones may share a common pass-through. The output signals of the two microphones may share one or more conductors in the pass-through. One microphone may support the other on the mask, or the microphones may be physically separate, or the microphones may be formed as one unit. The invention also relates to a mask having at least two microphones.
