Clement R.

Developing an audio product that needs to hit its performance targets from the first iterations? I design loudspeakers, transducers and embedded audio systems, from simulation through to production. Double master's degree in acoustics & vibrations and in electroacoustics. 8 years in acoustics and industrialization, 3 of them freelance. I support hardware teams, audio brands and manufacturers across the full chain: specification, simulation, prototyping, measurement, tuning and manufacturing. What I do: - Loudspeaker & enclosure design (1–3 way): Hi-Fi, pro audio, IoT, marine, in-wall/in-ceiling - LEM / BEM acoustic simulation and system modeling - FEM analysis: structural modes and acoustic air loading - Electrical, Magnetic & thermal simulation (FEMM): motor design, flux, voice-coil heating - Audio DSP, filtering, tuning and SPL optimization (C / SigmaStudio) - Driver selection and Thiele-Small parameter validation - Bracing, sealing, vibration control - 3D-printed prototyping and free-field acoustic measurement - DFM and manufacturing support: CNC, ABS, metal, supplier follow-up Most clients come to me when: - their prototype doesn't meet performance targets, - mechanical constraints degrade acoustic behaviour, - thermal or magnetic limits show up late and force a redesign, - they need to avoid months of trial and error, - the product has to be predictable, measurable and production-ready. I combine advanced simulation with real industrial constraints to deliver accurate, stable and manufacturable audio products. Recent work: - Full pro-audio system (2×18" sub, 2×15" point source, 2×8" line array): design to production - Transducer thermal optimization & DFM: material selection against operating temperatures, demagnetization limits, motor robustness - High-end Hi-Fi loudspeaker - IoT acoustic tuning and architecture optimization - Complete in-wall / in-ceiling home cinema line (5 SKUs) How I work: Clear specification → simulation → 3D-printed prototype → free-field measurement → tuning → DFM and supplier support. Simulation and measurement stay under one roof, so every iteration is fast and verified. No guesswork, no "magic recipes". Just physics, engineering and measurable performance. Engagements: I mainly work on full projects, but I also take on focused engagements: prototype audits, simulation campaigns, technical design reviews before production release.
