WebFeb 9, 2024 · Audacity can generate test-tones and/or generate white or pink noise. To properly measure frequency response you need a calibrated measurement mic. It comes with a frequency response curve (usually a file) for the mic itself so the variations can be corrected-for. USB measurement mics are also SPL calibrated. WebFrequency response measurements are a visual representation of the headphone's sound pressure level (SPL) across the full frequency spectrum for human hearing (typically 20-20khz). In other words, these measurements represent the amount of energy (volume) each part of the full frequency range has.
