Acoustic calibrators are essential in any field where precise measurements are needed. Field calibrators use a test signal at a well-known level – something like a tone generator at specific frequency or frequencies (depending on the model). The level shown at the sound level meter’s screen can thus be directly compared to the nominal value.
Apart from the field calibrators, even more accurate calibration (laboratory calibration) can be performed. All the equipment needed to build up your own Calibration Laboratory is available as off-the-shelf products from Norsonic! The calibration system Nor1504A is capable of calibrating virtually any type of sound measuring instruments, sound calibrators and microphones commercially available, provided that they have been designed in accordance with applicable international standards. Hence, the system is by no means limited to Norsonic products alone.
We also provide Nor1517A system from Norsonic, which measures the airflow resistance in porous materials according to ISO 9053-2:2020. It provides a fast and accurate measurement from test material of various forms and sizes, while being very easy to setup and to use.
