The Nowsonic Calibration was specially developed as a tool for room analysis, e.g. for calibrating the auditorium in a theater or concert venue, for recording studios (control and recording room) and for acoustic analysis on stage.
The small diaphragm condenser features an electret capsule with a 6 mm diameter. The polar pattern is omnidirectional. Therefore, it is equally sensitive for sound from all directions. Each microphone is separately calibrated to ensure a measurement that is as linear as possible over the audible frequency range. The frequency response and sensitivity are specified in the supplied measurement protocol.
In addition to acoustic room analysis, the Calibration can also be used for special recording purposes: Thanks to high SPL capabilities up to 149 dB SPL, it can even be used with very loud audio sources without clipping.
