measurement microphone / condenser / 1" / pressure
Bruel and Kjaer
1", pressure, free-field
The Bruel & KJaer Type 4144 1" pressure-field microphone does not require a pressure response below 8kHz. The diaphragm damping provides a flat pressure frequency response over a wide frequency range.
When the measurement of the local pressure is the focus, as with coupler measurements and wall or surface measurements, it is recommended that a pressure-field microphone be used.
The superior Type 4144 stability in combination with the high sensitivity and low inherent noise make this microphone a great choices for coupler measurements and laboratory type measurements
