There is provided a microphone device with which an operation state of the microphone device may be easily checked and that may effectively reduce noise to be played back, the noise being caused by vibration that has propagated through a table or the like. When the speech frame fails CRC error detection or the SNR is below a pre-specified value, a bad frame indication flag is set. The prosthetic capsular bag further provides an integrated refractive surface, providing a means for experimentally determining an effective lens position prior to inserting an IOL. The support band having mounting means for mounting on and or within a structure via compression and or expansion. The non-cellular adhesive is preferably sprayed onto a roof substrate and prior to complete solidification thereof the roof membrane or roof insulation is pressed into the adhesive so that the matting becomes embedded therein. A composite pattern of an intersection of the second pattern and the complement of the pattern of the etch-resistant material portion is transferred through the template layer.
