  • Simulating 3D Room Modes: Voxel Finite-Difference Helmholtz Solvers for the Browser

    Simulating 3D Room Modes: Voxel Finite-Difference Helmholtz Solvers for the Browser

    Below 200 Hz, a room's sound is standing waves, not rays. How we solve the 3D wave equation for any room shape and show its bass modes in the browser.

  • Why Ray Tracing Fails Below 200 Hz: Hybrid Wave PDE and Geometrical Acoustics in Small Rooms

    Why Ray Tracing Fails Below 200 Hz: Hybrid Wave PDE and Geometrical Acoustics in Small Rooms

    In a small room, bass behaves as standing waves, not rays. Why ray tracing gets it wrong below 200 Hz, and the hybrid wave-and-ray model that doesn't.

  • Why $10,000 Speakers Sound Bad in an Untreated Room (And How Physics Fixes It)

    Why $10,000 Speakers Sound Bad in an Untreated Room (And How Physics Fixes It)

    In an untreated room you hear the room, not the speakers: bass peaks and nulls of 15–20 dB. Why EQ can't fix them, and what placement and treatment can.

  • Physics vs. Folklore in Room Acoustics: Where Rules of Thumb Work, Where They Break, and How 3D Simulation Fixes It

    Physics vs. Folklore in Room Acoustics: Where Rules of Thumb Work, Where They Break, and How 3D Simulation Fixes It

    The 38% seat rule and 15% panel coverage hold in a shoebox room and fail in real ones. Where acoustic rules of thumb work, and what to do where they don't.

  • Solving Low-End Mud in Project Studios: Practical Speaker/Seat Positioning and Acoustic Panel Placement

    Solving Low-End Mud in Project Studios: Practical Speaker/Seat Positioning and Acoustic Panel Placement

    Three steps to fix muddy, boomy bass in a home studio: stop EQing wall nulls, find the reflection points before hanging panels, then trap the corners.
