Ambient room attenuators like the VoxGuard work by attempting to eliminate as much of the room ambiance as possible so that the microphone only captures the sound of the voice. This allows the engineer to introduce effects such as reverb or echo during the production phase.
Yes. The VoxGuard is up to twice as large as competitive products. The larger the absorptive area you can create around the microphone, the greater the absorption you will enjoy and less of the ambient noise will enter the microphone from flanking.
Flanking is a term used by acousticians that refers to how sound will come over an acoustic divider or boundary and wrap around it. By increasing the size of the divider, you make the boundary more difficult for unwanted sound to flank. Today, highways are often flanked with walls designed to keep traffic noise contained. Some have reflective shields that angle inward towards the traffic to further reduce flanking. The VoxGuard employs the same scientific approach.
Increasing weight by increasing the density of the acoustic panels will generally improve the low frequency absorption. Thus the reason we employ high density open cell acoustic foam. But as anyone who has some technical background knows, deep low frequencies have long wavelengths that are both omnidirectional and generally more powerful than high frequencies. This means that they will generally pass through or go around most devices and will be almost impossible to control. As such, the VoxGuard is intended to control the voice range, not bass.
When we set about to improve the designs that are already on the market, the first thing we wanted to do was address the problems that many have encountered such as the heavy metal fittings that are impossible to tighten and often cause the microphone stand to become unstable. We started by eliminating any unnecessary weight from the absorptive shield. Then we balanced the VoxGuard shield so that the center of gravity would be work with a typical recording microphone. Not only is it significantly more stable than the competition, because of the light weight, the VoxGuard is able to be employed in many more applications.
They look cool and give you the impression that they are technically advanced. We feel that form, function and performance are more important than visual appeal.
