01dB: dBTrait, Data Processing software

dBTrait software has been developed for the post processing of environmental noise measurement data. It represents almost 20 years of expertise and development, including the basis of short LEQ theory. Standardised results (such as time history of a given acoustical quantity, Leq and statistical index LN values over selectable periods, etc.) are available, but the real advantages of dBTrait start where those of most dedicated instruments end: time history of a selected spectrum frequency band and associated statistical calculations, playback of audio recordings from within the data plot, frequency analysis, identification and evaluation of noise sources with intelligent coding techniques, etc. Associated with the uniquely powerful environmental noise acquisition dBTrig software, the dBTrait application software is an ideal investigation tool, which makes data processing easy and helps the user to analyse any given noise nuisance problem.

01dB: Opera Suite, Monitoring Management and Processing

Opera Suite consists of several complementary software programs dedicated to control and operate OperaEX and OperaRF stations. These software programs, dBadmin, dBData, dBTrait and dBReport, allow for environmental monitoring: * Noise and Vibration Building Sites Management, * City Noise Management, * Noise Monitoring of the Airports, * Noise Monitoring of Recreational Activities, etc.

01dB: OSSR, Noise Sources Recognition

OSSR, an innovation for sound environment: the recognition of noise sources Dedicated to the recognition of noise sources, OSSR software presents innovative features in the field of management information and the acoustic impact of transport on the environment. OSSR software uses audio data recorded on-site and it extracts the occurrence of sound sources related to transportation (aircrafts, trains,...) while rejecting other noise sources. Input files are in MPEG-3 format and can originate from Blue Solo Sound Level Meters for Noise Measurement or Oper@ Noise Measurement Systems for Monitoring in the Environment.

01dB: CadnaA, Noise Prediction

CadnaA (Computer Aided Noise Abatement) is the leading software for calculation, presentation, assessment and prediction of environmental noise. Whether your objective is to study the noise immission of an industrial plant, of a mart including a parking lot, of a new road or railway scheme, CadnaA is particularly adapted to entire towns and urbanized areas too: virtually unlimited object number, very high calculation speed, powerful visualization functions, complete display in 3D, calculation of the time traces, web editing…

01dB: dBBati, Building Acoustics software

Sound insulation, Rooms criteria, Expert analyses and standardised automatic reports dBBati software is a tool program devoted to building acoustics. When used with Solo Black Edition Sound Level Meter or Symphonie Acquisition Unit, dBBati software adds to your computer the capabilities of a digital audio recorder, a Type 1 sound level meter, a frequency analyser and a system optimised for measurements in buildings. dBBati sotware allows for octave and 1/3 octave acquisition, transfer and calculation of reverberation times and decays, and standardised insulation. RASTI and MLS Modules are also available in option, for a relevant use both in the laboratory and in the field. dBBati software incorporates all the existing international standards (ISO 717, ISO 140, ...), as well as European directives for product noise labelling. It is perfectly adapted to the applications of the building acoustics : Sound insulation, Acoustic correction, Noise of equipments...

01dB: dBFA Suite, Signal Acquisition and Processing

Taking advantage of ACOEM's long-time experience (release 1.0 of the software dates from 1990), dBFA Suite is composed of dBRTA for real-time recording and analysis and dBFA for post-processing of noise and vibration signals. dBFA Suite is now offering standard and advanced features for real-time and off-line post-processing. dBFA Suite is the software suite for multi-channel processing with real-time acquisition and post-processing: Average 1/n octave, 1/n octave vs. time, Average FFT, FFT vs. Time, FRF, white/pink/sine/sweep sine generator (if available on hardware), colour spectrogram and waterfall, tacho acquisition, calculation on spectra and signals, signal edition, import of Teac/Sony files, reporting module, order analysis, sequencer, transient/impact, Me’scope export, Matlab Communication, etc.

01dB: dBPower - Software for Sound Power

The dBPower software is designed to comply with standards ISO3741 in reverberant room, ISO3744 in normal rooms, ISO3745 in semi anechoic and anechoic environment, ISO3746 in external open space. Additional EC standards Directive 2000-14-EC and ISO7779/ ECMA074 are supported. dBPower has a user-oriented Graphical Interface, high measurement/calculation capabilities available in a few clicks, a remote control for most relevant operations in very low noise measurement conditions.

01dB - dB4 - Recorder And 4-Channel Analyzer With dBFA Suite software

dB4 Recorder and 4-channel Analyzer with dBFA Suite software, solutions composed of: Recorder: Signal recording, white/pink/sine/sweep sine generator (if available on hardware), tacho acquisition. Analyzer: Simultaneous signal recording and real-time multiprocessing and monitoring, Average 1/n octave, 1/n octave vs. time, Average FFT, FFT vs. Time, FRF, white/pink/sine/sweep sine generator (if available on hardware), color spectrogram and waterfall, tacho acquisition. PostProcessing: Calculation on spectra and signals, signal edition, import of Teac/Sony files, Reporting module.
