Array-Ring48-75

with 48 channels for applications in the acoustic lab

The Ring48-75 is the first differential array working together with the Multi Channel Data Recorder (mc dRec).
The ring on which the microphones are placed is a custome made carbon fiber construction to assure a constant microphone position over long time.

Array-Ring32-75

with 32 channels for applications in the acoustic lab

The ring arrays are measurement systems designed for applications in acoustic labs. The "LN" (Low Noise, only Ringarray 32 and 72) version can be used to measure very faint sounds. Depending on the signal's spectral composition, the measurement distance should be between 0.35 (Ringarray 36) and 10 meters (Ringarray 72). Longer ranges are possible for measurement frequencies above 1 kHz (except Ringarray 36). The ring arrays are equipped with studio microphones and MicBus microphone connectors, similar to all other arrays.

Array-Ring36-35

with 36 channels for applications in the acoustic lab

The Ring 36-35 is ment to serve trouble shooting on sources of small and mainly high frequent emiting sources.

The array allows to get close-ups of objects such as mobile phones, digital cameras or even dentist drills.

This array contains the same studio microphones as all other arrays, but this time placed in a custome made carbon fiber construction.

Array-Ring72-140

with 72 channels for applications in the acoustic lab

The Ring72-140 has been designed to merge the purpose to find relatively high and low frequency emissions during the same measurment. In order to use this array a special modified version of the dRec40 with 76 channel has to be used.
Like with all other Arrays we have used the same studio microphones in order to get fairly comparable data.
