SentineX Noise Monitoring System

If a tree falls in the woods, does anyone hear it? SentineX does!

Sentinex Noise Monitoring units are self contained, free standing noise recording/monitoring units that can be placed anywhere, both indoors and outdoors, to provide continuous monitoring of environmental noise levels as well as to identify sources and types of noise.

Sentinex Noise Monitoring Units record 15 min statistical data, 1/3 octave data (at 5 sec to 15 min intervals) and real time audio (MP3) files continuously each day.

Each unit is accessible through a LAN when working on the field unit, or a web browser (intranet/internet) when downloading and analysing monitoring data or listening to audio files.

Units can be triggered remotely to start or stop recording (e.g. 1 min statistical noise levels for sleep arousal), report on recent events, send messages if pre-defined events occur during day or night, or send and receive predefined SMS messages.

A typical daily noise report includes:

  • 15 min statistical data (LA1, LA10, LA90 or user defined)
  • LAeq,15min and LAeq,period noise levels
  • LAeq,15min in 1/3 octave
  • LAeq,15min in the 12.5 to 630 Hz range (or user defined)
  • Wind direction, wind speed, temperature, humidity and rainfall

  • Digital audio recording 24 hours per day 7 days per week
  • A meteorological station
  • In-field diagnostics using a solid-state computer
  • Web communications using NextG, GPRS, ADSL or 56K modem
  • Web browser that can present the results in real-time

Where can it be used?

  • Real-time noise monitoring in accordance with statutory requirements
  • Remote monitoring of industrial developments when audio diagnostics are required for noise source determination
  • Noise complaint diagnostics when attended monitoring cannot be sustained
  • Assessment of sleep arousal events

Other Applications

Sentinex can be tailored for individual, site specific requirements, and has a range of applications in addition to noise monitoring.
