Norsonic 139 Noise Nuisance Recorder
BS4142 measurements
Rechargeable battery
Class 1 | Type 1 Sound Level Meter
Compact, portable case
The NOR139 NNR kit is a lightweight, easy to use noise nuisance recorder. Easy to deploy and analyse results.
Sound recording can be trigged by an external hand switch, by a level trigger (requires option 16) or by a manual key push. An adjustable pretrigger records events up to 99sec before the trigger point.
Several recording formats are supported, ranging from 8, 16 or 24 bit and with sampling rates of 12 or 48 kHz. Using 48 kHz sampling and the stored sound signal may be used for further processing. The Nor139 has a large dynamic range – exceeding 120 dB.
Another useful feature is that you may play a 10 sec reference tone – sine wave, pink or white noise in the beginning of a measurement to set a reference level when later replaying recorded data.
The NOR139 NNR kit comes in a hard, tough case, enclosed in a discreet rucksack for subtle deployment.
