1/2 "-precision microphones

1/2"-precision microphones

There are three common application fields for capacitive precision microphones: free, pressure or diffuse field.
The output of these three different types is similar at low frequencies, but with higher frequencies it becomes critical to choose the right type of microphone for optimal test results. For each microphone, all three field types can be specified; however, the field type is named for which the microphone has the most linear frequency response.
1/2 "microphones are suitable for the most common applications in the field of sound measurement.The microphones presented here consist of a microphone capsule and a preamplifier, which are supplied calibrated and sealed as a system.
