What Is The Importance Of The Vent Hole Position In A Preamplifier? |
|
Answer» The VENT HOLE should be in the sound field whenever possible and operators must be careful not to cover the vent hole during mounting. This only affects low frequency response. But large changes in static pressure may be problematic if a microphone is not properly vented. A SIDE vented microphone is recommended for measuring low frequencies within a cavity or TUBE where there is a large pressure differential between the pressure INSIDE and outside the cavity.
