  • Page 7 Phantom powered microphone systems use a 3 pin XLR connector. A phantom powered microphone sys- tem should use a 48V phantom power supply or signal conditioner for optimum performance; however these microphone systems may be powered with a 24V or a 12V phantom power supply, but this will limit the maximum output voltage.

  • Page 8: Taking Measurements

    4.0 Taking Measurements The following formula is used to calculate the pressure measured by the microphone from the output voltage signal. The sensitivity of a microphone is typically measured at 250 Hz. Pressure (Pa) = Voltage (mV) / Sensitivity (mV/Pa). The lowest amplitude a healthy human ear can detect is 20 millionths of a Pascal (20Pa).

  • Page 9: Maintenance

    Windscreens and Nose cones Wind induced noise can be reduced by using a windscreen. This can offer some protection against dust particles and mechanical damage. In the presence of high-speed airflow from a well-defined direction, such as wind tunnels, a nose cone is recommended. When using windscreens and noise cones, the frequency response of the microphone will be attenuated at higher frequencies.
