Option SET - Sound Emission and Transmission

With the expert system Option SET sound power spectra can be automatically generated based on technical system parameters of a sound source (e.g. electric power in kW, volume flow in m3/h, rotations in 1/min etc.). Thus a unique system capable of modeling various kinds of sound sources is achieved.
Option SET comes with about 150 predefined modules (sound source descriptions) for technical sound sources such as electric and combustion engines, pumps, ventilators, cooling towers, gear boxes etc. The range of sources and systems can be extended by the user himself. The sound power spectra calculated with Option SET can be addressed to point, line or areas sources after having specified their respective technical parameters.

 Model of a row of cooling towers

 
On the one hand, Option SET will considerably simplify the possibilities of modeling sound sources; on the other hand, it allows to model complex arrangements of sound sources, parts of which can be linked to each other. With option SET you can not just model the sound radiation from an individual sound source (e.g. electric motor), but model also the sound transmission in a chain of sources (e.g. ventilator with two ducts connected). Further, based on the predefined modules you can model even more complex sound source configurations describing the sound radiation of a whole technical component (e.g. cooling tower).

Features

  • Calculation of frequency spectra of radiated sound power determined from the technical parameters of a sound source
  • Modeling of complex facilities and devices with multiple sound sources and radiating areas, reproducing their inner sound flux (e.g. cooling towers and pipe systems)
  • Established pool of data from predifined sound source models immediately accessible
  • Data pool can be easily extended by user-defined sound source models
  • Inserting a silencer in a sound flux string automatically reduces the emission of all subsequent radiating areas
  • Noise mitigation measures can easily be checked regarding their impact at receiver points by adjusting the technical parameters accordingly (volume flow, thickness of sheet metal)
  • Speeds up your project work by reducing the time required for data retrieval of noise emission data
