SoundPLAN supports proposals to ISO/TR 17534-3:2015 and ISO 9613-2

SoundPLAN supports and complies with changes that have been proposed to ISO/TR 17534-3:2015, (https://www.iso.org/standard/66128.html), relating to acoustics software for the implementation of standards associated with the calculation of sound outdoors.

Additional recommendations have been proposed for the calculation method of ISO 9613‑2. This International Standard ISO 9613-2 outlines the measures necessary to ensure a high quality of calculation methods for acoustic measurement.

The Technical Report (https://www.iso.org/obp/ui/#iso:std:iso:tr:17534:-3:ed-1:v1:en) contains additional recommendations for the calculation method that are agreed on to be implemented in software quality ensured test cases with detailed results that allow checking the correct implementation and forms to declare conformity with these requirements by a specified software product. SoundPLAN is a member of the working group that has helped develop these new measures.

The recommended changes outlined to ISO 9613-2 will help improve the accuracy of calculated sound levels, which can currently differ significantly.

 

SoundPLAN Training in US by Navcon 30-31.10.2014

SoundPLAN.essential.contour.map

This two day SoundPLAN training seminar by Navcon is intended for both SoundPLAN users and those engineers, technicians and hygienists tasked with environmental,
community, and/or industrial noise measurement, planning, analysis and control. Lecture topics include sound propagation theory, national and international noise modeling standards and guidelines (for road, rail, industry and entertainment facilities), noise regulations and noise assessment methods.

Attendees will use the SoundPLAN software to develop noise models, generate noise contours, make noise level predictions at sensitive receiver locations, assess noise mitigation scenarios such as optimizing noise barriers (length, height, absorption, etc.), relocating equipment, applying lagging
treatments, installing silencers, etc. The principal objectives of the training are to introduce attendees to the SoundPLAN user interface and to show how noise modeling software can be used for noise planning, noise mitigation and noise assessment studies.

SoundPLAN supporting ICBEN 2014

ICBEN is the International Commission on Biological Effects of Noise. Its goal is to promote a high level of scientific research concerning all the aspects noise-induced effects on human beings and on animals including preventive regulatory measures and to keep alive a vivid communication among the scientists working in that field. ICBEN is a non-profit organization that has no legal identity of its own and entirely depends on its members and its officers that voluntarily work for the organization. The means to achieve its ambitious goals are mainly based on the unique structure of ICBEN.

SoundPLAN: Complex Structures Allowed!

None of the standards designed for the calculation of environmental noise cover the complexity of the real world. All standards stop with screening over an obstacle. Some explain multiple screening for two independent screens but do not recognize that a building with a front and a back are not two completely independent screens. Most of the standards do not explain wind and weather sufficiently. In any case, there are many gaps in the common standards.

SoundPLAN has solved some of the geometrical shortcomings representing the real world. For openings of tunnels from roads and railways, for example, there is a dedicated tunnel object allowing the user to enter the geometry of a tunnel and define how far into the tunnel absorptive material is used. From these parameters, the program calculates the emission from the tunnel in the normal calculation. Tunnel objects are unique to SoundPLAN.
