For a microphone a shock mount helps reduce noise from the surrounding area, without affecting the sound of a microphone. Shock mounts are commonly used on studio microphones to prevent unwanted noise. The shock mount is used to partially isolate the mic from vibrations that might otherwise be transmitted through the mic stand, causing unwanted sounds to be added to the output signal. Don't wait until mixdown before you notice that there's a foot tapping behind what might otherwise be a stellar performance. Make sure you have the proper shockmount for your studio condenser mic. This mount was designed to be used with the AudioTechnica AT4033, AT4040, and AT4050.
