Content and learning outcomes

Course contents

Sound. Frequency response and distortion. Linearity. The loudspeaker driver and Thiele/Small parameters. Closed and vented boxes. Baffle step. Effects of the room. Crossover filters. Computer simulation. Measurement techniques, sweep measurements, impulse response. Fourier transform, spectrum, perceptual evaluation.

A loudspeaker system is designed in project form.

Intended learning outcomes

Participants shall after the course be able toDescribe how the electro-dynamical loudspeaker converts an electrical signal to soundDescribe the effects of the box design on the sounding properties of the loudspeaker systemUse simulation tools and moderns measurement techniques as aids for loudspeaker and crossover designchoose appropriate measurement methods for the different problems in loudspeaker designChoose appropriate methods for perceptual evaluation of loudspeaker systems.
