Noise affects all our lives... ...but the problems can be solved only if we accurately measure the noise. Starting with an order to the Anglo-French supersonic Concorde project, we have for more than 40 years used our technical expertise to develop sound instrumentation of high precision and quality. Combining advanced technology and user-friendliness, we focus on the user and applications rather than on the complexity of the instrument. Our close relationship with our main clients and distributors in more than 20 countries throughout the world ensures contact with users and the development of products in parallel with the emerging needs for them. Based on our "all-in-one" philosophy, we develop complete solutions which can be compared to portable laboratories. This means that the user can make measurements, analyse the data and print out the results on-site. Our retrofit policy is a fundamental part of our business concept. Most of our instruments are of modular design. If new standards or new technology call for an update of the instrument this can easily be carried out by the factory or one of our local service centres. Hence, early customers have an instrument as modern as our newest customers.

| Calibrators The use of sound calibrators dates back to the days when it was easier to design a stable sound calibrator than a stable sound level meter. Today, sound measuring instruments, in general, are as stable as the sound calibrators.
However, measuring microphones are very delicate devices designed to fulfil very rigid specifications. This makes them vulnerable and subject to damage unless care is taken.
One may therefore say that a calibrator is just as much a verification of proper operation as it is a device for re-adjustment of sensitivity of sound measuring instruments.
The Norsonic selection of sound calibrators comprises three types, viz. the Nor1251, the Nor1252 and the Nor1253. The difference between them lies in their accuracy; while the Nor1251 is a class 1 calibrator and the Nor1252 is a class 2 calibrator, the Nor1253 is no less than a class L calibrator. It also satisfy all class 1 requirements!
