How to Read Headphone Frequency-Response Measurements
What fixtures, targets, smoothing, fit variation, and uncertainty mean before you compare two curves.
What the graph shows
Frequency response describes level across frequency under a defined measurement setup. It does not directly show comfort, distortion, dynamics, or listener preference.
Fixture and coupling
Headphone fixtures approximate an acoustic load. Results from different fixtures should not be overlaid without understanding their calibration.
Targets are references
A target curve is a comparison reference, not an absolute boundary between correct and incorrect sound.
Positional variation
Repeated placements show whether a feature is stable. A single trace can hide uncertainty.
Prototype demonstration data — not a real product measurement.
Conclusion
Read the conditions first, the broad trends second, and narrow peaks with caution.
