A Real Time Sound Acquisition System with Post Processing Capabilities

In Stock

The Ngara™ Real Time Sound Acquisition System offers full measurement flexibility by recording data in a format that allows any combination of frequency weightings (A or C) and statistical intervals to be retrieved after the measurement is completed rather than specifying the required output prior to starting the measurement.

The Ngara™ can output the following values at in either Fast or Slow time weighting:

Equivalent continuous SPL: Leq
Short term equivalent continuous SPL: short Leq
Maximum SPL: Lmax
Minimum SPL: Lmin
Percentile sound levels: Ln (1% to 99%, Max 8 values)

The Ngara™ Real Time Sound Acquisition System is capable of storing high quality, high resolution audio waveform files that can be processed by Firefly to extract a large range of customisable data.

Firefly allows the Ngara™ to become a 1/1 and 1/3 octave analyser by extracting octave band data from recorded waveform files as well as displaying level over time graphs for all every statistical interval the Ngara™ system is capable of producing.

In Industrial Noise Monitor mode the Ngara is able to produce band pass filtered results as well as all pass filtered results

Additional Features

Additional to recording sound level data, the Ngara™ Real Time Sound Acquisition System is capable of the following auxiliary functions:

Recording temperature and battery level information
Programmable power on and off timer
Synchronising the internal clock with internet time servers via SNTP
Level and time triggerable recording on a range of customisable parameters
Level and time triggered power/voltage output
Remote recorded data transfer via FTP
Automatic email alerts triggered on a range of customisable parameters
12V Auxiliary Power output allowing you to power 12V equipment (up to 1A) using Ngara™

Items Included with Purchase

1x Ngara™ Real Time Sound Acquisition System
1x 64GB(min) Tested USB Flash Drive
1x Ngara™ Battery Power Cable
1x Rugged Case (including custom insert)
1x Collapsible Microphone Post

Optional Extras

12V Sealed Lead Acid Battery
The Ngara™ system can be purchased with a 12 Volt Sealed Lead-Acid Battery (either 24 or 26 Amp-hour). The battery is rated for up to 10 days of continuous logging.

Lithium (LiFePo) Battery
The Ngara™ system can be purchased with a 12 Volt Lithium Iron Phosphate Battery. The battery is rated for up to 10 days of continuous logging. A dedicated LiFePO charger is required.

Solar Panel
The Ngara™ system can be purchased with an solar panel to allow remote logging with a much longer operating time. The Solar Panel option is often used in conjunction with Noise Cloud to implement a long term logging system.

Modem
The 3G/4G modem allows the Ngara™ system to connect wirelessly to the internet at locations with mobile coverage. This option allows the Ngara™ to be controlled from any location as well as allowing the user to remotely download recorded session data. (Note: The Modem Option does not include a SIM card)

Push Button Trigger
The Push Button Trigger allows the user to trigger the recording of audio waveform data with the push of a button.

AC Output
The AC output option affixes a 3.5mm audio jack to the Ngara™ system that serves as an output for the audio recorded by the microphone.

Noise Cloud™
Ngara can work in conjunction with ARL's new service Noise Cloud™ to allow for remote logging directly to a cloud-based server where data from multiple noise loggers can be stored, viewed and downloaded.
