Headphone Test Video
PC Magazine (pcmag.com) has posted a video and step-by-step guide on how they test headphones. Tim Gideon, Lead Audio and Video Analyst for PC Magazine, shows us how he tests headphone and earphones.
The featureless face in this picture is not a department store mannequin-it’s our new testing system for headphones and earphones. Manufactured by HEAD Acoustics, in Germany, the ACQUA system and HMS II.3 head and torso simulator consists of a life-size human head with measurement microphones placed in each ear, roughly where the eardrums would be. It’s all connected to a computer and an outboard box that sends audio signals to earphones sitting in the artificial ears. The output of the earphones is then measured by the internal microphones, and the results are displayed in graphs and data sets in the software.
In the step-by-step guide Tim addresses topics like: What Is Frequency Response?, Our Testing Methodology and Understanding the Results.
