NoiseAtWork V2019 is by far the easiest tool available on the market today for creating interpolated contour maps based on any type of measurement, such as Noise in dB(A), Temperature in ˚C, Humidity in % or Gas concentration in ppm. Simply read in any CAD, PDF or scanned image map and enter your data points by clicking on the map at the locations where you have done your measurements. You will be amazed how simple it is!

New options in the V2019 release include additional predefined indicators and the ability to copy & paste items. Click here to download V2019.

DGMR Software and Stapelfeldt Ingeniersgesellschaft will exhibit together as Softnoise on 6-9 November at Acoustics 2018 in Adelaide. Please feel free to visit our Softnoise booth and receive the latest information on iNoise and Predictor-LimA V2019.

Description

During this iNoise user meeting I will handle your questions regarding iNoise 2018 and the ISO 9613 method. Most likely we will dive into the nitty gritty details of the ISO 9613 and 17534 methods. So put on your diving gear!

Description

This short course gives insight in the world of environmental noise modelling and prediction. Attendees can expect an up to date and realistic view on this topic from an acoustic consultant who became involved in the implementation of noise calculation methods in software. The workshop includes an instruction on the new version 2019 of the Predictor software. Also a comparison is made between the Predictor software and the iNoise software.

Today we have released iNoise 2018.2. This release includes new functionality as well as improvements on several existing functionalities. Pro and Enterprise configurations now include a calculation option for automated calculation of the Valley correction according to IOA GPG TO ETSU-R-97. This will save consultants valuable time when applying the valley correction. New for all configurations is the option to show the exact calculated rubber band detour paths around buildings and barriers in the 3D view. This gives even more insight in the way iNoise calculates. Visit the download page to see all changes

DGMR Software and Stapelfeldt Ingeniersgesellschaft will exhibit together as Softnoise on 26-29 August at Inter-Noise 2018 in Chicago, USA. Please feel free to visit our Softnoise booth and receive the latest information on our software products Predictor-LimA, Oden, iNoise and NoiseAtWork.

DGMR Software and Stapelfeldt Ingeniersgesellschaft will exhibit together as Softnoise on 27-31 May at Euronoise 2018 in Crete. Please feel free to visit our Softnoise booth and receive the latest information on CNOSSOS-EU and our software products Predictor-LimA, NoiseAtWork and iNoise. For more info on CNOSSOS-EU click here to view the latest newletter.

With the new version 5 of NoiseAtWork the applicability has increased substantially. Not only noise, but any measured indicator can now be mapped as interpolated contours within minutes. For instance Temperature in ˚C, Humidity in % and Gas concentration in ppm. To demonstrate how versatile NoiseAtWork is we decided to add a simple option in V5.1 for monitoring a CSV file with measurement values. When the file changes NoiseAtWork will automatically import it again and show the new interpolated contours. As a result you get a dynamic map. See the video

A set of 12 tutorial videos is now available in the iNoise Gallery at https://dgmrsoftware.com/products/inoise/gallery/. The videos will guide new users step by step through the process of setting up and calculating models with iNoise.

The IOA GPG TO ETSU-R-97 recommends that a correction of +3 dB (or +1.5 dB if using G=0.0)  should be added to the calculated noise level of a wind turbine for propagation “across a valley”. The following criterion of application is recommended: hm ≥ 1.5 x (abs (hs – hr) /2). In this criterion hm is the mean height above the ground of the direct line of sight from the receiver to the source (as defined in ISO 9613-2, figure 3).

Although the formula is simple enough, the criterion when to apply the valley correction is not. Because there is no exact and unambiguous definition of ‘propagation across a valley’, the consultant will have to decide ‘manually’ in which situation a valley correction is applicable.

When it is decided that a valley correction is needed, determining the mean height hm manually can be time consuming. As the calculation of hm is part of the ISO 9613 calculation method, the iNoise Free software can be helpful. In iNoise the calculated mean height above the digital terrain model for any chosen receiver – wind turbine combination can be displayed.

DGMR Software will exhibit at Acoustics 2018, 23-24 April in Cardiff, UK. This will be a good opportunity to talk to the developers of iNoise and NoiseAtWork and experience the latest features in the software.

Join us for the coming Live Q&A Webinars where we will answer any iNoise or NoiseAtWork question you might have, or simply learn from our answers on questions from others! Click here to view and register for the coming Q/A Webinars.

See https://software.dgmr.nl/videos/NAW-in-2-minutes.mp4. New options in the V5.1 release include an integrated demo mode and support of PDF as background drawing next to CAD (DXF/DWG) and image files (BMP/JPG). Click here to download V5.1.

The new iNoise 2018 release includes several new powerful features such as a quick and easy calibration option for bitmaps and a very convenient option to convert sound pressure (Lp) to sound power (Lw) for point, line and moving sources. Also the sound power database has been extended with CNOSSOS-EU based sound power levels for light, medium and heavy vehicles driving 50, 80 or 100 km/hr.

New: Calibrate option for using bitmaps as background maps

The new calibrate option in iNoise 2018 makes calibration of bitmaps extremely easy. With the iNoise menu option ‘View | Background Maps’ you can add multiple GIS, CAD and Image (bitmap) files as Background map layers underneath your model. iNoise automatically recognises georeferenced image files that include a separate World file. Such georeferenced image files can be purchased or can be created with GIS software. However calibrating an image file yourself is not difficult at all. With the new intuitive Calibrate option in iNoise 2018 you can do this within seconds. Learn how to, simply by watching instruction video 6 on our website: https://dgmrsoftware.com/products/inoise/gallery/

New: Lp to Lw option to convert sound pressure (Lp) to sound power (Lw)

With the new Lp to Lw option in iNoise 2018 for Point, Line and Moving Sources the user can now quickly determine the sound power level (Lw) of the source based on a measured sound pressure  level at a certain distance.

New: SourceDB option

SourceDB is a separate software that enables storing, searching and sorting your own sound power data, as an extension of the European IMAGINE database. SourceDB supports 1/3 octaves, a script language to define parameters and formulas to calculate the Lw and adding pictures to the sources. A sound power level in SourceDB can be easily copied and pasted in a source of an iNoise model.

New: CNOSSOS-EU sound power levels for road traffic noise

The default sound power catalogues ‘SourcePower_Octave.cat’ and ‘SourcePower_Terts.cat’ now include sound power levels for light, medium and heavy vehicles driving 50, 80 or 100 km/hr. The sound powers are taken from the CNOSSOS-EU method. In combination with the moving source item this makes it more convenient to calculate road traffic noise according to the ISO 9613 propagation.

iNoise has been received very well. There are now already hundreds of registered licenses, and that in such a short time! Although iNoise is seen as a ‘new kid on the block’, the user friendly and intuitive DGMR-GUI for environmental modelling is in use for more than 20 years now. The DGMR-GUI is the centre of the Windows development platform of DGMR since 1995 and has been implemented in numerous software applications.
