Norsonic AS

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

Norsonic helps to protect the environment.

Our products are used worldwide to reduce the noise and vibration impact for the human being. Research and development departments in many companies use our equipment to develop less noisy products. You will find our equipment monitoring noisy factories, airports and construction sites across all continents. Health and safety inspectors use our products to protect workers from hearing damages. This is just examples for the use of our products with the aim of creating a more silent world.

However, Norsonic has a responsibility as a leading global supplier of sound measuring solutions to also control the production process and develop new products that are environmental friendly.

We have a documented health, safety and environmental policy approved by the Board of Directors and follow all Norwegian and European environment requirements to producers of electronic equipment.

The company publishes a yearly environmental status in the annual report. All hardware products meet the RoHs Directive (EU directive 2002/95/EC). Norsonic offers a certified take-back and recycling service for all our products and participate in a certified program for collection and recycling of packaging material.


The Norsonic Calibration Laboratory (NCL) is an accredited laboratory (Norwegian Accreditation No. CAL 022) for the calibration of measuring microphones, sound calibrators and sound measuring instruments such as sound level meters and sound analysers. Norwegian Accreditation is one of the signatories to the EA Multilateral Agreement for mutual recognition of calibration certificates (European Co-operation for Accreditation). The accreditation states that the laboratory meets the NA requirements concerning competence and calibration system for all the calibrations contained in the accreditation. It also states that the laboratory has a satisfactory quality assurance system and traceability to accredited or national calibration laboratories.

Note that the Norsonic Calibration Laboratory calibrates all brands!

Calibration is not restricted to the Norsonic range of equipment!
You can send your microphones, calibrators and sound measuring instruments to us for calibration whenever needed, but calibration contracts to ensure calibration on regular basis are also available.

Contact us for details on prices and delivery times. We recommend that you contact us before sending equipment to us to keep the time you're without your equipment at a minimum. For your daily verification of the performance of your sound measuring equipment Norsonic offer a range of sound calibrators.

The basic equipment (Nor1504A) used in the Norsonic Calibration Laboratory is also available for sale to those who want to build up their own sound measuring equipment calibration facility.
