Tools and Resources
Tools, publications and other Hub of Acoustics resources, born from the daily work of designing and building acoustic instruments.
Rialto
Soundboard Deflection Gauge
Precise and easy to use anywhere on the bench, the Rialto measures the point deflection of the soundboard under a known applied force — the most direct way to quantify the soundboard stiffness.

Arena
Bluetooth Speaker
Arena is a Bluetooth speaker designed for Chladni pattern visualization. Connect it to any tone generator app, place it above the soundboard and — at the relevant frequencies — the vibration modes become visible in real time.

Articles, guides and manuals.
Building Guitars with Torrefied Spruce (ARTICLE)
Published in the Artisan Guitar Show magazine (April 2026), this article offers an accessible take on the effects of torrefaction on spruce soundboards — measuring density, stiffness, damping, and sound radiation coefficient across 24 samples and simulating the behavior of a complete soundboard through finite element analysis. How much of what is said about torrefied wood holds up to measurement — and what does it mean for instrument makers?
Periodic Table
of the Frequencies
The Periodic Table of Frequencies maps notes and their frequencies for every fret, relating them to the instrument’s vibration modes. The bottom section shows the ideal placement of resonance peaks to avoid known issues such as beats and wolf notes.
Available in A3 (210×297 mm) or Tabloid (11×17″) size, both for guitar and mandolin makers.
