SONOMETERS AND SOFTWARE ASSOCIATE

We offer two types of LARSON DAVIS sonometers:

LxT with Blaze software: Easy to use sonometer classified 1 or 2 allowing the measurement of  Leq, Lmax, Lpeak, TWA (dosimetry) and third octave spectra, More (French documentation only).

831 with DNA software: a more powerful sonometer classified 1 or 2 allowing Leq, Lmax, Lpeak, third octave, temporal recording, reverberation time measurement (TR).

ENVIRONMENTAL ACOUSTICS SOFTWARE

IMMI is a noise cartography and forecast software for all types of sound sources (road, railway, industrial,  leisure activities, airports) and for creating all types of noise maps, even the strategic noise maps of cities.

More than 20 different methods of European and international noise calculation are available in IMMI. The software calculates the outside noise propagation by taking into account the entire physical phenomena acting on the sound propagation. The results can be presented as noise maps or as detailed numeric tables.

Close Field Holography measurement system (HELS):

The SenAH system from SENSOUND is based on the HELS method (Helmholtz equation least square).Capabilities:

• To visualize the sound pressure, the intensity & particulate speed 

• To chart external and internal surfaces in 3D

• To analyze the stationary and non-stationary sources

• To determine the noise sources and the transfer paths

• To show the narrow bands and the octave bands

• To cover a very broad frequency spectrum 

• To present data in the form of a 3D surface grid or as photos

• To make 3D movies with frequency sweeping 

• To identify the vibratory modes responsible for the noise

• To offer order tracking of non stationary sources

• To create a hierarchical table of the contributing sources

This system is offered in 2 forms :

• A multichannel acquisition system for more than 32 inputs

• A compact acquisition system with 4 inputs

System of far field aerial array measurement (BEAMFORMING) :

SOUND CAM system from  SIBAEI and HASTRICH is based on the beamforming method and can be used in many situations such as :

• Engine radiation

• Wind mill noise

• Traffic noise

• Factory noise

• Etc...

The acquisition front end used for this system can be the OR38 from OROS.
