About

Built by a silencer engineer.

SpectraSim is developed by Ahmad Abosrea, a mechanical engineer and product and project manager with about ten years in duct and silencer acoustics software and consulting. It exists because silencer engineers need flow and acoustics in one dedicated, transparent tool.

Who builds SpectraSim?

Ahmad Abosrea is a mechanical engineer and product and project manager. He has worked for about ten years in duct and silencer acoustics — on the software side and in consulting — and develops SpectraSim himself.

SpectraSim exists because silencer engineers need flow and acoustics in one dedicated, transparent tool — with the theory, the equations and the quality checks behind every number visible to the engineer.

Why SpectraSim exists

What problem does SpectraSim solve?

SpectraSim is a Windows desktop application for duct acoustics with flow. It predicts the pressure drop and the acoustic performance — transmission loss, insertion loss and radiated sound — of exhaust mufflers and silencers from one 3-D CAD model, coupling a CFD flow solver with a finite-element acoustic solver in one guided workflow.

Two tools for one muffler

Back-pressure in one program, acoustics in another, and the data carried across by hand. SpectraSim uses the same CAD and the same boundaries for both.

Suites built for analysts

General multiphysics suites solve anything, but a routine silencer needs an expert and long set-up. SpectraSim is set up for mufflers and silencers in one guided workflow.

1-D models stop at the first cross-mode

Network models miss cross-modes, complex internals and temperature gradients. SpectraSim solves the 3-D geometry.

How we work

Principles

  • Focused on mufflers and duct products

    One field, done properly — not a general multiphysics suite.

  • Transparent theory and validation

    Every setting has its equation and references in the F1 Help; every validation number states its reference type.

  • Offline and private by design

    The program never connects to the internet. Your models never leave your computer.

  • Honest limits

    Features that are not verified yet are labelled Experimental; features still to come are labelled Planned.

Besides the software, we run design studies on request. Engineering services
