CadnaA (Computer Aided Noise Abatement) is the software for the calculation and presentation, assessment and prediction of noise exposure and air pollutant impact. Whether your objective is to study the noise immission of an industrial plant, of a mall including a parking lot, of a new road or railway scheme, or even of entire towns and urbanized areas: CadnaA is designed to handle all these tasks.

CadnaA is a transparent and easy to use platform for everything from simple checks up to extremely complex and scientiic investigations. The clear separation of the 3D-model in its natural environment and the applied calculation method offers lexibility unique in this area. It is even possible to use the same model when noise levels are calculated based on different national standards without any need to modify the model.

CadnaA Standard includes all noise types (industry, road and railway) and all available standards and guidelines for each noise type as well as a multi- lingual user interface.

CadnaA Basic comes also with all noise types but with one standard or guideline for each noise type and the user interface is limited to one of the available languages.

With CadnaA Modular all noise types can be selected separately and are combined with one of the available standards or guidelines for each noise type.


Computer Aided Noise Abatement

offshore oil platforms

Acoustiblok In The Field

Acoustiblok Inc. recently performed an acoustical assessment of offshore oil platforms at the request of a Fortune 100 oil company.  Extremely high noise levels have become a great concern regarding health and safety of workers in this industry.  The Acoustiblok All Weather Sound Panel will no doubt be part of our recommendation as well as mechanical vibration isolation. Acoustiblok is using the new Cadna-A Acoustical Prediction software in conjunction within field measurements to develop solutions to these Acoustical problems. 

An oil platform is one of the most hostile environments on Earth, with corrosive salt spray, high winds, extremes of hot and cold, and of course petrochemicals and solvents - and any exposed material that is easily damaged by impact will not last long. Designed for harsh environments and industrial applications, Acoustiblok All Weather Sound Panels are the ideal solution for oil platform noise control.


Calibrated Equipment

Acoustiblok provides rental of laboratory quality acoustical test equipment, with technical support, to our customers who require on-site acoustical testing to validate or compare sound abatement installations. Contact Acoustiblok for pricing and availability of this service.

Nor270(H) Dodecahedron
Loudspeaker
loudspeaker

The Nor270 is a high power loudspeaker with omnidirectional characteristics. It fulfils the directional characteristisc required by the ISO 140-3 Standard and delivers a continuous sound power level of 120 dB when driven with pink noise over the frequency range 50-6300Hz via the Nor280 power amplifier.

A version with even higher output is available under the name Nor270H. The sound power level here is 123 dB when driven with pink noise over the frequency range 50-6300 Hz using the Nor280 Power amplifier.

The dimensions are 405 mm diameter and a weight of 14,5 kg. The high power version (Nor270H) has a weight of 19 kg.

Source signals may be provided by the Sound Analyser Nor121, the Sound Level meter Nor118, the external MLS generator Nor257 or the internal Noise Generator in the Nor280.


Nor280 Power Amplifier Power Amp

This power amplifier is the 4th generation of specially designed units for building acoustic measurements from Norsonic. It is less than half the size and weight, but twice as powerful as its predecessors.

  • Specially designed for Building Acoustic measurements
  • Lightweight and rugged construction
  • Self contained noise generator
  • 500 Wrms output power
  • Emits 120 dB sound power level in the 50-5000 Hz frequency range when used with Norsonic dodecahedron loudspeakers types Nor250 or Nor270

Applications

  • Sound insulation measurements
  • Reverberation time measurements
  • Absorption coefficient measurements

Norsonic Nor130
Sound Level Meter
Sound Level Meters

The Nor130 Series of Sound Level Meters are designed and manufactured to the latest sound level meter standards and comprises two products. The Nor131 is a Class 1 (precision) instrument whilst the Nor132 is designed in accordance with the less accurate Class 2 requirements. Both meters offer the same features with exception of the detachable preamplifier which is only available on the Nor131 version.

Features

* Single measurement range
* Extremely simple operation
* Parallel LAeq and LCpeak
* Large internal memory
* Clock synchronized measurements
* Single measurement range
* USB interface
* Allows use of microphone extension cable (Nor131 only)
* Large back-lighted display
* Complies to IEC and ANSI standards
* Real time 1/1 octave (optional)
* Real time 1/3 octave (optional)
* Statistical analysis (optional)
* Level versus time (optional)
