New software DS3 (February 2022) Presentation

DS3 for Analysis/design of Direct Field Acoustic Radiation Test of Payloads (DFA/X/N/T in technical literature).
It simulates radiated pressure from a swarm of electromagnetic speakers from voltage and allows retrieving speakers state from specified pressure levels at control points.

For Analytical SEA (ASEA)

Software SEA+ / SEAWOOD *            Version info             New RRI Function in SEA+ v2022
SEA+ is the most complete and advanced SEA solution, easy and fast modeling, backed up by 30 years of application expertise (throught consulting, traininig and support)

Optional Modules :

SEA-Foam & SEA-Cyl **

* SEAWOOD : Software SEA+ Lite version & SEA-Foam module for Timber Building Acoustic

** SEA-Cyl : Optional Module of SEA-Foam (from SEA+ version 2018)

SEA-Cyl Module integrates AcouCYL, a spectral method for the vibroacoustic modeling of multilayered cylindrical systems developed and owned by CSTB, the French Technical Research Center of building industry.
SEA-Cyl allows performing IL (Insertion Loss) and TL (Transmission Loss) predictions using TMM (Transfer Matrix Method) calculation formulated in cylindrical coordinates.SEA-Cyl module is dedicated to cylindrical structures. In SEA+ GUI, SEA-Cyl can be in one-click substituted to SEA-Foam calculations when the supporting structure is curved (singly-curved and doubly-curved shell SEA+ subsystems).


For Experimental SEA (ESEA)

Software SEA-TEST           Version info

Software SEA-XP

Main differences between SEA-TEST and SEA-XP :

SEA-XP includes both acquisition software (driving National Instruments (NI) cards) and ESEA post-processing.
SEA-TEST post-processing only -SEA-TEST uses a modal test protocol with referenced nodes to drive the post-processing. Data are imported in UFF format allowing any modal test protocol acquisition system exporting in UFF to deliver input data to SEA-TEST.
SEA model is defined as group of nodes in SEA-TEST while it is a group of records in SEA-XP. SEA-TEST is more flexible as the position of the nodes can also be stored and groups of nodes can be easily re-ordered through the list of nodes
SEA-TEST allows specifying ESEA test independently of the acquisition with known position of nodes. Position of nodes is not recorded in SEA-XP and the philosophy is more on-the-fly sub-structuration into subsystems -ESEA Post-processing is nearly identical in SEA-TEST and SEA-XP except that SEA-TEST allows similar to Virtual SEA post-processing and can also directly import VSEA sub-structuration from FEM.


SEA+ / SEAWOOD and SEA-TEST are license-controlled applications. The license control mechanism is based on RLM from Reprise Software Inc.
