Continuous monitoring of environmental noise for short term projects, particularly in a remote area, has always presented unique challenges.  To avoid complex installations and frequent visits to remote locations, The Modal shop offers the NoiseTutor from Larson Davis - a portable, integrated solution for rapid deployment in the field creating the ability to publish real-time data to the web and send automatic alerts via email or SMS/text messaging.

The NoiseTutor system uses the versatile Larson Davis Model 831 sound level meter to take measurements, allowing the system to perform basic data logging, octave band analysis, exceedance logging, measurement history, and sound recording.  All data can be further analyzed using Larson Davis DNA software.  In addition to the 831, the NoiseTutor consists of a compact PC and appropriate modem for internet connection (cellular, WiFi, or wired Ethernet).

NoiseTutor allows users the ability to respond quickly to sound events by publishing user selected real-time data to the web with alerts sent via email. For an example of published data, please view a live data stream here.

If real-time data viewed via the web is not needed, the NoiseTutor can also run in an off-line mode.  In this mode, data is stored on the machine itself and is periodically uploaded to a FTP site.  At this point the standard .slmdl files and .ogg audio files can be downloaded for processing in SLM Utility-G4 or DNA software.
