Norsonic AS products

Reference sound source for Sound Power measurements. The rugged and compact design makes it well suited for both laboratory and field use. The design ensures a stable and uniform sound power output with unique long-term stability. The reference sound source Nor278 is designed to produce a stable and uniform sound power output with unique long-term stability. The high sound power output makes it ideal for sound power measurements in a noisy environment. The rugged, but yet portable and light weight construction is perfect for field us as well a laboratory use. Every effort is made in the design to ensure a uniform frequency response and optimum directional characteristic well inside the requirements in ISO 6926.

Norsonic was the first company to introduce sound recording of noise events in a sound level meter. This greatly improved the work to identify a noise event and to judge whether it should be excluded or not from the overall noise level. However, it’s quite time consuming to listen through numerous sound recordings. The three-dimensional Nor1297 Noise Compass significantly reduces time spent on judging if a noise source should be a part of the overall noise calculation or not, simply by defining which direction the noise is coming from. When used together with Norsonic’s sound level meters and NorCloud, the device provides a three-dimensional vector pointing at the sound source. The system may also operate off-line and collect the data on the instruments SD card for later analyse in NorReview.
