SIDLAB Suite is a combination of software and hardware solutions for the analysis and measurement of sound generation and propagation inside duct networks. This can be applied to Intake and Exhaust systems, Power generation, Oil & Gas pipe networks and HVAC systems. It offers a complete characterization of the system, including both simulation and validation measurements. SIDLAB Acoustics and SIDLAB Flow design the system to have a good acoustic performance keeping the pressure drop low enough. The results are then validated using SIDLAB Measurement or SIDLAB Acquisition in the SIDLAB Rig.
SIDLAB Optimization and Parameterization tools offer larger possibilities for an efficient design. SIDLAB calculations are done in MATLAB, and the source code is offered. This is a good advantage for advanced users to perform their custom analyses. Calculation time is typically a few seconds on a normal PC. Post-processing within SIDLAB is simple and straightforward, with the possibility to save the results in different formats. SIDLAB compiles a long experience and know-how of accurate modeling for all types of duct acoustic applications in research, teaching and consulting.
The following modules are available and priced separately:
– SIDLAB Acoustics
– SIDLAB Flow
– SIDLAB Acoustics HF
– SIDLAB Measurement
– SIDLAB Rig
This module models the generation and propagation of low frequency sound in complex duct networks. All standard element models are validated and are based on the best and most recent models published in the literature. The users have the possibility to add their own elements as user defined elements. SIDLAB FLOW
This module is an add-on SIDLAB Acoustics. This is a very quick 1D tool to calculate the pressure drop introduced by the designed muffler system. It calculates the flow distribution and pressure drop inside the network using a two-port formulation, and feeds the results into the acoustic calculation in SIDLAB Acoustics. The acoustic performance of some elements like perforates is very dependent on the amount of flow inside the element. SIDLAB Flow uses the same network built in SIDLAB Acoustics. SIDLAB ACOUSTICS HIGH FREQUANCY
This new module models the propagation of sound inside ducts in the high frequency range using power method. In power based techniques, the source-path-receiver model is used, see Figure 1. In this model, the source is the sound-generating device; the path comprises everything that affects the sound as it travels from the source to the receiver, and the receiver is typically the site where a person hears that sound. The term element collectively describes the source, receiver, and path components. The receiver location hears the sum of all sound traveling to that location. Depending on the application, there may be several sources of sound, and the sound from each source may travel to the receiver along one or more paths. Regardless of the number of sound sources and paths, each path is analyzed individually; then the superposition of all paths is considered. This model is widely used in HVAC applications. SIDLAB ACQUISITION/MEASUREMENT
SIDLAB Acquisition is used to acquire the measurement data needed to characterize the passive acoustic properties (e.g. Transmission Loss) of two-port elements (e.g. exhaust or intake mufflers). SIDLAB Acquisition is provided together with a Data Acquisition System and the measurement microphones. It automates the measurement procedures accounting for different theoretical and practical considerations. Different excitations (random or stepped sine) can be used. The results are stored in different formats compatible to SIDLAB Acoustics and can be used to simulate a complete system. SIDLAB RIG
This is the test rig for the measurement of the acoustic properties of mufflers for different exhaust/intake and HVAC applications
