Managed Monitoring via Web Portal

NoiseScout displays the noise levels measured by the XL2 Sound Level Meter live in your web browser. The measurement data recorded out in the field is presented online in charts and dashboards. Multiple noise level meters can be monitored simultaneously within the map view, thus providing localized geographic visualization for all noise levels at a glance. Identified users can access all their projects, control their monitors or create basic view modes, allowing stakeholders to oversee their noise level data.

The XL2 Sound Level Meter is configured remotely. The NoiseScout monitoring solution reports compliance violations and data connection irregularities by email. Audio recordings of the periods with the highest sound level, as well as the ability to listen to live audio, assists with the identification of causes of noise. From this information, preliminary reports can be generated while the measurement continues. This facilitates quick responses to noise issues so that they are addressed before a non-compliance condition arises.

No data will be lost if communication to the NoiseScout Servers is interrupted. Measurement data is buffered for transmission at source on the XL2 Sound Level Meter. In case of any lost connection, the NetBox will synchronize the recorded data to the NoiseScout Servers as soon as communication is re-established. The NoiseScout Servers are built on a scalable architecture and the latest secure data center technology. The server network provides access to your data quickly and reliably.

NTi Audio manages and maintains the data synchronization and data storage for your convenience. This service is offered within an innovative “pay-per-use” credit scheme, providing transparent and predictable cost control. Usage is based on calendar days contained within the measurement data transferred from the XL2 Sound Level Meter to the server. Alternatively an annual subscription service is available.

Gateway to Sound Level Meter

The direct access to the XL2 Sound Level Meter is available around the world. The internet connection allows SFTP (Secure File Transfer Protocol) and remote access to the XL2. This offers the freedom to start and stop the online noise monitoring from your office or your mobile device; a useful tool for complete control.

All data files can then be retrieved remotely from remote XL2 Sound Level Meter even during an ongoing measurement. Also, the spectral data and audio files can be directly downloaded from the remote XL2.

The remote access allows full control of the XL2 Sound Level Meter. All remote measurement commands available on the XL2 are supported. For example, the current measurement data may be captured in real time into a computer application, e.g. C#, MS Excel or LabView. You may program a customized measurement application for remote sound level monitoring, audio analysis or automated measurement tasks.

Secure 24/7 Noise Monitoring

NoiseScout provides reliable on-site sound level measurements. The power supply is monitored and low voltage levels of any connected external battery pack are reported. Immediate action to facilitate uninterrupted measurements can thus be taken. In case of an external power loss, the XL2 Sound Level Meter will continue measuring using its internal battery. Once the internal battery too is exhausted, as soon as power is restored, the XL2 will restart automatically and carry on with the measurement.

Faster Reports with Data Explorer

NoiseScout further maximizes the success of the survey by reducing the time spent preparing the client report. All data can be exported to the optional Data Explorer PC software for detailed analysis. The NoiseScout system leaves the consultant free to concentrate on their key responsibilities, such as producing the client report, even before the XL2 Sound Level Meter has been collected from site.

Customer Comments

I Love It
“The XL2 is currently the world’s most versatile hand-held acoustic and audio analyser. I can do so much with it, and just love it! And in many ways, the associated Data Explorer software is much more versatile and easier to use than other leading industry equivalents.”
Glenn Leembruggen,
Acoustic Directions
, Australia

Very Simple to Use
"I must say that the instrument and the software are brilliant, and very simple to use, even for an old fogey like me."
Owen Clingan, UK

Better price with more versatility
"I am happy that you keep on developing new applications and uses for the XL2, it is quite a convenient and powerful tool. In my opinion it is a serious competition for the traditional sound level meters at a better price and with more versatility. The Type Approval is an important step forward in the acceptation of the system; even in situations where type approval is not really needed, it helps avoiding discussions on the validity of the measurements."
Ben Kok,, Netherlands

XL2 Data Explorer Software
"With regards to analyzing the recorded noise data: The idea of hovering over the marker text or locking the set of them is absolutely brilliant for assessing the tonality of a marked section. I could not have thought of a better system. And the percentile calculator letting you choose any marker, filter band or level parameter is just perfect."
Jason Dixon,, Australia
