Denon Sound Shield Portable Isolation
Get a more direct, isolated sound.
"Sound Shield is a portable, compact device that shields a microphone from the deleterious effects of audibly-destructive excessive ambience and near-field acoustic reflections. In a highly-reflective acoustic environment, a sound source will create multiple duplicate “ghost” images as its original acoustic output is multiplied many times over by nearby hard reflective surfaces. It is analogous to standing in the middle of several mirrors, resulting in many closely-spaced images close to the original, which makes it nearly impossible to get a clear representation of that original signal without distortion.
There are also scenarios such as outdoor recordings where ambient background noise or audible wind turbulence makes for a very unfocused, vague recording. Here too, the primary recording microphone needs to be isolated and shielded from extraneous noises and distractions.
Sound Shield is aptly named—it literally “shields” the recording microphone from the reflected images that result from an overly-live acoustic environment or the distracting background noise of a large, acoustically-“busy” setting. Sound Shield has five absorptive walls (three stationary, two foldable) consisting of sculpted sound-absorptive surfaces, backed by high-density EVA foam for additional sound attenuation. It can be custom-shaped around the microphone to create a very focused, precise vocal or instrument recording in any environment.
