Measurements of Sound Intensity

Sound Intensity is the preferred method to accurately measure sound power when you have a difficult acoustic test environment such as a high background noise or if equipment is in a poor acoustic test room. The Nor150 fitted with sound intensity option and sound intensity probe kit Nor1290 is a perfect tool for all kinds of sound intensity measurements. It is designed for easy use in all types of measurement conditions.

Norsonic offers 3 years warranty.

Nor1290 Sound Intensity Probe

Nor1290 Sound Intensity Probe

The Nor1290 probe kit offers a lightweight and rugged solution for rough environments. Mount a smartphone with NorVirtual App installed on the probe, and you are provided with single hand operation and the same measurement displays as on the Nor150. The remote system is fully synced, allowing you to put all your focus on the measurement task.

Sound intensity is a powerful measurement method in situations where traditional methods proves difficult or not feasible. With the new features of the Nor150, sound intensity measurements are significantly easier to accomplish than ever before, and may actually be less time-consuming than corresponding sound pressure methods.

Nor150 equipped with the sound intensity option and the Nor1290 probe kit is a powerful tool for all types of sound intensity measurements, from high-precision laboratory conditions to demanding and rough field use.

Thanks to the unique phase correction algorithm, only a 12mm spacer is necessary to cover the entire frequency range from 25 Hz to 10 kHz. This significantly reduces the time spent insitu, and allows measurements of highly reactive sound fields.

Sound intensity is especially suitable for sound power measurements of non-movable machinery in industrial environments, measurements of driven machinery, industrial plant exhausts and pipes both indoor and outdoors.

In-situ building acoustics may benefit from the intensity technique, both for transmission loss and sound leackage detection. And for research & developement applications, sound intensity provides powerful noise map visualisation.

Features

  • Compliant to IEC 61043 Class 1.
  • Unique phase correction allows measuring 25 Hz to 10 kHz with single 12 mm spacer.
  • Full on-board support for ISO 9614-2 sound power measurements.
  • Smartphone remote control for single-hand operation, all measurement data presented during measurement.
  • Intuitive warning indicators makes sound power measurements easy.
  • Measurement-based improvement suggestions helps the user on the way, no need to consult the ISO standard.
  • Pause and back-erase with L(t)-graph.
  • Integrates with Nor850 visual mapping and reporting software for advanced post-processing.
  • Configurable measurement sequence.
  • Full measurement edit support (segment exclusion, resize, retake).
  • Photo, text and voice annotation for individual segments.
  • Accepts legacy sound intensity probes.

Nor1294 Phase Calibration Coupler

Based on the innovative method invented by Norsonic to correct the phase response of a sound intensity analyser, the Nor150 offers the following outstanding unique features for sound intensity measurements; Measurement of the complete frequency response with the 12mm spacer with significantly higher dynamics than required in current ISO standards.

The procedure for this correction of the phase response is so conveniently integrated in the Nor150 that it can be performed very easily and quickly before each measurement!

For use with the Nor1290 Sound Intensity Probe.

The diagram shows that thanks to the new algorithm with a 12 mm spacer, this phase calibrator makes the Nor150 Sound Intensity measurement system fulfill the requirements described by IEC 61043 for a 100 mm spacer:

Nor850 Reporting software

Create professional reports fast, accurate and easy. Instead of using your own created excel reports, spending time on maintaining it to the latest revision of standards, try out the Nor850 reporting software. This ensures you make accurate and up to date reports at a glance.

The Nor850 reporting software takes advantage of the modules used in the Nor850 measurement system but offered as individual reporting and post processing packages for

  • Building Acoustic
  • Room Acoustics
  • Sound Power
  • Sound Intensity

 

Measurements taken manually by use of the Norsonic sound level meters Nor140, Nor145 or Nor150 are easily imported into the reporting modules. The powerful multi project tool allows you to easily search across projects to extract and work with data from multiple projects. The Nor850 Reporting system can be upgraded to a complete Nor850 Measurement system at any time.

Building Acoustics
Level, reverberation and background measurement files are placed into the respective table folders by simple drag & drop technique. Even complete building acoustics files containing all data in one file may be imported. The full range of Standards for building acoustics such as the in-situ ISO 16283, laboratory ISO 10140, ISO 717, and service equipment ISO 10052 as well as national version such as American ASTM Standards, are selectable.

Room Acoustics
The reporting module for room acoustic supports the open plan office standards ISO 3382-2 and -3.

Sound Power
The sound power module supports the ISO 374x series of standards. Calculation properties as well as informative text for the excel reports are inserted and edited for the final calculation of the sound insulation indices or sound power value.

Sound Intensity
The sound intensity reporting module supports ISO 9614-1 and -2 and the Sound intensity transmission loss in accordance with ISO 15186-2.

NorVirtual / NorVirtual App

NorVirtual emulates the Nor13x, Nor140, Nor145 and Nor150 on a PC. Freeware.

NorVirtual App for smartphones emulates the Nor145 and Nor150. It is a 1:1 copy of the screen and keyboard of the instrument. Whatever view the sound level meter has (graphs, menus, tables etc.), the same view is visible on the device screen. The mouse can be used to operate the virtual keyboard.

NorVirtual for Nor145/Nor150 supports all communication channels. Hence, you may connect to a Nor145/Nor150 via modem, Wlan, LAN etc and use the program as a simple remote control. In combination with NorConnect you have a simple and intuitive solution for remote control and download measurements.

NorVirtual App can be downloaded from Apple Store or Google Play.
