The Libri GmbH The Art and Science of Headphone Design

A headphone is a small, stubborn acoustic system - a driver, a sealed cavity, a pad against your skull - and every decision you make about it shows up in the measurement. This is the bench guide to those decisions: how sound is made, how it's measured, and how to read the frequency-response curve every reviewer reaches for and most read wrong.It works from first principles to a finished tuning - driver excursion, the physics of the sealed cavity, the target you voice toward, distortion, and the build steps that hold it together. Thirty-three chapters across six parts, plus seven hands-on build guides and seven appendices, including a glossary and supplier lists. Every figure is drawn, not photographed - diagrams you could redraw at the bench.Written by an engineer who has spent 25+ years in pro audio and tuned headphones where the coffee is cold and the seal is never quite right. For the people who actually open the cup: DIY builders, audio engineers, and anyone who wants to stop trusting graphs they can't interpret.
