Norsonic is extending the environmental noise monitoring product portfolio with a new set of products that meets the increased demands of tomorrow’s noise monitoring systems. The system consists of the Environmental Monitoring Terminal, EMT, Nor1520, the Control and data management software, NorMonit, (Nor1022) and the calculation and reporting software, NorReview, (Nor1026).

The system is scalable from a single noise monitor that operates off line as a self contained unit to a fully integrated multi-channel noise monitoring system reporting data on line to a host computer.
A wide range of noise parameters can be measured in addition to continuous sound and video recording. The system also supports all types of weather parameters and other external transducers such as GPS.
Every effort has been made to make a fault tolerant system. It starts with the EMT featuring a double walled aluminium cabinet thereby preventing the system from over heating and the buildt in backup battery that will cover mains power interruptions. Continues with the noise data being measured using the well known Nor118 sound analyser, which has been independently type approved by PTB. Then it ends with the NorMonit software that should the system to loose connection between the host and the noise terminal for up to 24h will, as soon as the connection is re-established, pick up the data transfer.

Measured noise parameters

The noise is measured using the well-known sound analyser Nor118. Type approved by PTB, Germany, as well as several other national laboratories. Nor118 is capable to measure a wide range of noise parameters needed in a noise monitoring system, such as Leq, Lmax, Lmin, LSpl, Lpeak, Ln and 1/1 or 1/3 octave spectra.

Available spectral weighting functions are A, C and Flat Z. Available time constants are Fast, Slow and Impulse.

Environmental Monitoring Terminal Nor1520 PD EMT Ed.1 Rev.0 English 09.06 3 The benefit of using Nor118 in a noise monitor is that the annual calibration cost and down time is kept on the lowest possible level since it is a standard sound analyser that can easily be substituted with another one. The Noise data is stored locally in the instrument in case of a data transfer failure or a failure in the EMT system computer. Data is erased in Nor118 when a confirmed data transfer is done.

Sound and video recording

Noise source identification is often an important issue in order to determine the source of a noise pollutant. Audio and video can be continuously recorded by use of the internal system computer. The recording quality of the noise and video can be selected to limit the amount of data storage and speed up the transfer. The playback of the sound and video is easily done by use of the NorReview application SW. The sound and video are displayed as separate markers in the L/t graph. Simply clicking on the desired marker makes the playback of the sound or video.

Special system solutions

Customers have often special requirements that can not be covered by standard solutions. Norsonic has supplied custom made systems since the company was founded in 1967. Often only a small adaptation is necessary to fulfil a special need. Our technical solutions are modular and flexible, designed to meet the customer’s requirements.

A typical example is a gas terminal in England where the customer needed to measure temperature gradient over a 9 metre span in addition to the noise level. Norsonic developed a 10m microphone mast, and adapted the software to fulfil these requirements. Similarly a project wanted to have a built in flat screen in the noise terminal in order to collect data offline in the field. For this application the environmental terminal Nor1520 was made larger to make a 17” flat screen to fit in.
