Acoustic Guides & Tutorials
In-depth acoustic engineering tutorials backed by physics calculations, room mode solvers, and 3D simulations.
Home Studio Acoustic Treatment Guide
The complete guide to treating home recording studios, mixing rooms, and project studios. Fix low-end room modes, mirror reflection points, and bass decay.
Home Theater Acoustic Panels Guide
Optimize Dolby Atmos 5.1.4 / 7.1.4 surround sound systems. Improve dialogue clarity, manage rear-wall reflections, and prevent bass rumble.
Glossary
Natural acoustic standing waves formed by sound reflecting between parallel room boundaries, creating bass peaks and nulls.
The time required for sound pressure level to decrease by 60 decibels after the sound source has stopped.
The boundary mirror coordinate where speaker sound reflects directly to the listener within 20 milliseconds.
A phase interference artifact caused when direct sound combines with delayed reflected sound, creating a series of notch filters.
The crossover frequency separating low-frequency discrete room modes from high-frequency specular reverberation.
A rapid, ringing echo sound created when high-frequency sound bounces repeatedly between two hard parallel walls.
Comparison between thick porous/pressure bass traps targeting low frequencies (<200Hz) and standard mid-high absorber panels.
The difference between removing sound energy from a room (absorption) and scattering sound energy evenly across time and space (diffusion).
