Product Description

The Nor145 is a sound and vibration analysis platform in the form of a convenient, hand-held sound level analyser. There are a huge range of available optional features but some are quite niche and unlikely to be regularly required by most practitioners. The Nor145 Packages offer all the features likely to be required for Environmental Sound and/or Building & Room Acoustics.

Practitioners can purchase the Environmental Sound Package, The Building and Room Acoustics Package or the combination of these two in the Comprehensive Consultant’s Package and know that all the main bases of their measurement requirements for Environmental Sound and/or Building and Room Acoustics are covered. It’s important to note that these packages don’t just provide basic functionality. The functionality of both the Environmental Sound and Building and Room Acoustics Packages are incredibly comprehensive and advanced.

With all main bases covered, it’s great to know that if an unusual measurement requirement arises it is likely that there is an additional Nor145 available to cover it.

If you are looking for a sound level analyser specifically to tackle an unusual problem the Nor145 is probably the solution you are looking for. Examples include ultrasound (up to 40 kHz), infrasound (down to 0.4 Hz), high level noise (up to 163 dB), low level noise, discriminating between sound based on arrival direction. If you need Sound Intensity the dual channel Nor150 is currently the only portable solution on the market.
