If you're interested in doing headphone measurements (either in a lab for work or as an enthusiast), Audio Precision's new APx517B acoustic analyzer is an ideal solution. It's also an excellent measurement setup for those engineers who are now spending a lot more time working from home, as it's far more affordable -- and more compact -- than other high-end audio analyzers.
Here's Dan Knighten* from Audio Precision demonstrating how easy it is to set up the APx517B straight from its box to measuring headphones -- literally just a few minutes of setup.
Known for their state-of-the-art audio analyzers, Audio Precision recently announced the new Audio Precision APx517B Acoustic Analyzer which is specifically designed, configured, and built for the production-line testing of speakers, microphones, headsets, the wide range of consumer electronics incorporating speakers and microphones, and (most significantly to this community) headphones.
While the APx517B is optimized for fast setup and reconfiguration for production line use, it is also a perfect analyzer for those doing headphone research and development, as well as for headphone measurement enthusiasts. The APx517B combines an Audio Precision analyzer for signal generation and acquisition, a headphone amplifier, and a microphone power supply, and optional Bluetooth capabilities, all in a single chassis.
The APx517B also measures impedance using the Kelvin measurement technique which subtracts the resistance effects of the cable itself and inaccuracies caused by the less-than-ideal source impedance in a power amplifier, for more accurate impedance measurements.
Audio Precision says that it should be operationally inaudible in a typical office environment with its thermostatically controlled fans, which you'd also understand as a big deal if you've worked around audio analyzers.
And here's Dan Knighten again, this time showing a Bluetooth headphone test setup (below):
