NoisePAD™

Universal 4-channel Noise and Vibration Analyzer

With a size of just 226mm x 156mm x 28mm and a weight of only 950g the NoisePAD™ is our smallest sound level and vibration meter complete with display and four measuring channels. The sample rate of each channel is freely adjustable between 200Hz and 51.2kHz. The instrument also features a 24-bit signal generator and two trigger and rpm inputs. The NoisePAD™ closes the gap between our hand-held sound level meters of the Tango™ series and the Soundbook™.

Equipped with an Intel™ ATOM Cherrytrail processor the octave and FET analyzer combines high performance and low power consumption. This makes the NoisePAD™ the ideal instrument for monitoring noise and vibrations. The touch screen gives easy control and allows field configuration of the instrument. The internal 128GB SSD can be used to simultaneously record and store measuring and real-time analysis data at full bandwidth from all channels, even for several days.

The NoisePAD™ has a large 8-inch TFT screen that enables use as a tablet. This allows a much clearer display of the measuring data compared to the usual hand-held sound level meter. Sound level, level curves with marker traces as well as FTT and third-octave spectra can be viewed simultaneously.

Our new powerful Apollo filter processor allows highest-precision real-time analysis with a large number of channels and a low energy consumption. Integrated weighting filters complying with IEC 61672 for sound level meters, Class 0 filters complying with IEC 61260 for the 1/3 or 1/1 octave analyzer, filters for the evaluation of mechanical vibrations complying with DIN ISO -7919, ISO -2954, ISO -10816 and DIN45666 as well as high and low pass filters provide resource-saving calculations directly on the hardware. The 24-bit ADCs safeguard a high signal bandwidth with a linearity range >110 dB (typical) complying with DIN 61672 and a sample rate of up to 51.2 kHz (switchable per channel).

As a very special feature the NoisePAD™ has also been designed as an IEC 61043 Class 1 sound intensity analyzer. The software supports simultaneous sound intensity measurements with two sound intensity probes. The two integrated cameras can be used to take photos or videos to document the measurement process. The instrument features a highly accurate 24-bit signal generator for phase calibration.

The NoisePAD™ supports the simultaneous measurement of noise and vibration in the work environment. The activity of the worker and the position of the sensors can be captured using the integrated cameras. For the measurement of human vibrations the instrument integrates HVMA weighting filters complying with DIN EN ISO 8041, ISO-2631, ISO-5349, ISO-8662, UNI-2614, UNI-11048 and UNI-9916.

The light-weight NoisePAD™ offers the ideal feature for the mobile structural and modal analysis. Our SAMURAI™ FRF option supports excitation with an impulse hammer as well as a shaker. The intuitive software guides the user through several easy measurement steps. Analysis of the measured data can be done on the instrument immediately after the measurement. The integrated signal generator output can be used to drive the shaker.

The integrated high-end tablet PC offers all functions and interfaces of a regular notebook allowing to post-edit the measured data virtually everywhere. Thus the NoisePAD™ combines the performance of a high-quality measuring instrument with the capabilities of a PC.
