Environmental Noise Monitoring Applications

The EM2010P Portable Environmental Noise Monitor is for temporary installations, although the noise processor can be removed from the case and mounted indoors on a wall.

For a more permanent installation with power available, please see the EM2010 Environmental Noise Monitor.

Portable Noise Monitoring Kit

The EM2010P consists of two weatherproof cases and a tripod. One case contains the noise processing unit and wireless communication devices. It also carries the microphone and cables.

The second case contains the 10-day rechargeable battery. This is in a second case to ease carrying and so that it can be easily swapped out in the field without having to disturb the noise processor. This is not only convenient but avoids opening the main case in poor weather conditions.

Mobile Connection

The EM2010P units connect to the Internet using the mobile phone network. The noise monitor regularly uploads measurements to a web server, where they can be viewed using a standard web browser. It also includes a WiFi connection for on-site connections and unit configuration.

  • Automatically connects and uploads measurements
  • Connection over GSM / 3G link
  • Works in most countries straight from the box (mobile signal required)
  • Connection, modem and SIM included in the package

Do I Need a Phone Contract?

No, the EM2010P/G and EM2010P/GA come complete and ready to go, as long as it is in a region with a mobile phone signal. The price includes the modem (built in to the noise processor box) and SIM.

The price for these units also includes the first year of your contract, which covers the use of the installed SIM (no extra data charges) and access to the web server to view the reports. After the first year, the cost to renew this contract is in the Ordering box above. To protect against inflation we can provide you with a multi-year contract from the start, otherwise renewing can be carried out when the time comes.

How It Works

The EM2010P logs the noise measurements throughout the day, usually storing the Leq and the L90 (along with a few other parameters) every five minutes. The monitor connects to the Internet every 15 minutes using the built-in modem and antenna and sends the latest measurements to the server.

To view measurements from the previous days, weeks, months, you just need access to the Internet and a standard web browser. You navigate to the data access web site and log in.

For more information on the presentation of the noise measurements, please visit our Reports tab.

WiFi Connection

The EM2010 noise monitor also has a WiFi connection available. This provides an easy on-site interface, which is used for configuring and calibrating. The monitor provides its own WiFi hotspot. Connection to it is similar to connecting to a router and you then use a standard web browser. The benefit is that you don't have to open boxes to get access to the unit during servicing and on-site configuration.

Noise Measurements and Reports

The only tools you need to view the noise reports are:

  • Web Browser (e.g. Explorer, Firefox, Chrome, etc.)
  • Connection to the Internet

You can view the measurements, produce reports and download the data to your computer if you need a local copy. This can be done from anywhere, as long as you have a connection to the Internet and username/password.

Monitors, Projects and Guests

Your online account can handle multiple noise monitors. If you have more than one EM2010 (fixed, mobile or mixed) they will all upload their measurements to the same account for easier measurement management.

You can configure multiple projects within the account and assign monitors to these projects. The reporting system is designed to deal with anything from a single noise monitor to multiple monitoring sites.

Guests can be added to your account and given access just to the projects that are of interest to them.

Noise Charts

Noise charts show the sound level changes over time. Plotting the LAeq, L90, L10 and Lmax, the chart on the right clearly shows the day and night time sound levels over a period of four days.

Charts can be printed or exported into PNG, JPEG, PDF or vector format.

Calendar View - Daily Noise Summary

A calendar view gives a summary of the average sound level (LAeq) for the period of interest each day. It clearly indicates if the limit has been exceeded on that day. Zoom the image on the right for a clearer view.

Clicking on a day provides a more detailed overview, including the noise limit times and a convenient link through to the sound level charts and noise tables.

Noise Tables

Results can also be presented on-screen in a simple tabular format.

As with the Noise Chart display, you can select the dates for the chart and, if you have multiple noise monitors, you can select which one to view.

These tables can be exported for custom analysis.

Alerts and Notifications

For noise compliance monitoring it can be essential to know about any problems as they occur, rather than looking at a report a few days later. The EM2010 noise monitor and reporting system can be configured to send you a text message or an email alert when an LAeq limit has been exceeded.

Exported Noise Measurements

The noise charts can be exported to the standard PNG, JPEG and PDF formats for inclusion in any custom reports generated in a word processor or similar application.

Tabular reports can be exported to the standard CSV format, which can be loaded into Excel or many other programs for further analysis and reporting.

Setting Up

The EM2010P/G and EM2010P/GA include everything you need to deploy the noise monitor and make unattended measurements for one week before recharging or replacing the battery pack.

The main steps for setting up are:

  • Fit the microphone on to the tripod
  • Connect the microphone cable to the noise processor
  • Connect the battery pack to the noise processor

The measurements will start automatically and be uploaded to the web server as they become available.

The Microphone

The microphone comes fitted with weather protection (rain, snow, etc) and a wind shield. It mounts on a stainless steel post which in turn fits on the tripod.

A 10m cable connects the microphone back to the noise processor. This cable can be extended up to 30m using standard RG-174 coaxial cable and suitable connectors.

Battery Power

The batteries are contained in a separate carrying case. This is to make transport easier (batteries are heavy) and to give the option of multiple batteries to swap in the field without opening the noise processor case.

The battery pack connects to the processor case, and noise measurement will start automatically when the power is applied. With a full charge it has sufficient power to run the noise processor and mobile internet access for at least ten days.

Options for the EM2010P

The following items are available as options for the EM2010P Portable Noise Monitor. Those marked [Factory Option] must be carried out at the time of manufacture, or the equipment will have to be returned for upgrade. Other options can be added at any time.

Class 1 Microphone [Factory Option]

The standard EM2010P meets the sound level meter standard IEC 61672 to Class 2 and ANSI S1.4 to Type 2. If your regulations demand the use of a Class 1 or Type 1 system then you should add EM2010UPG1 option to your order.

As the whole EM2010P measurement chain meets Class 1, the main change is the microphone capsule. Operating and installing the unit are identical to the Class 2 version.

Battery Pack

The standard EM2010P/G and EM2010P/GA kits come with one battery pack. An additional pack can be added, which can be swapped in the field, reducing downtime.

The EMPP1240 battery pack is supplied in a weatherproof carrying case, similar to the case that carries the noise processor. This allows for easy transport and the ability to swap batteries without opening the Noise Processor - appreciated on rainy days. A charger is also included.

Audio Recording [Factory Option]

For a positive identification of the noise source there is no better way than to listen to a recording. The EM2010/AG can be set to record the audio when preset conditions are met (trigger levels, etc). The audio is automatically uploaded to the server so you can listen when viewing the reports.

When you order the EM2010/AG Environmental Noise Monitor the price includes the mobile connection and reporting contract for the first year. This costs more due to the much larger amount of data involved.

Microphone Extension Cable

The EM2010 is supplied with a 3m microphone cable. This can be extended to 10m using standard 50 ohm RG-174 coaxial cable.

Computer Requirements

As the data handling and report generation is handled by a web server, the computer requirements are very basic. To view the reports online you need the following:

  • Access to the Internet (only low bandwidth needed)
  • Web Browser - Explorer, Firefox (Windows or Linux), Chrome, Safari - other standard browsers should work

If you want to download the measurements and work with them locally we recommend using Excel or similar spreadsheet. The files are simple CSV text files that will load into many different applications.
