How to Read a Frequency Response Graph on Headphones

Electronics & Technology Tutorial The Headphone Show

Andrew from The Headphone Show explains how to accurately interpret raw and compensated frequency response graphs for evaluating headphone audio quality.

🔑 Key Takeaways

  • 📊 Understanding the difference between raw and compensated frequency response graphs is crucial for accurate headphone evaluations.

  • 🎧 Compensated graphs should ideally show a flat line matching the target, indicating a neutral sound profile, whereas raw graphs display the true audio attributes.

  • 📈 Misinterpretations can occur if the compensation target is not publicly specified, making comparisons difficult and potentially misleading.

  • 🧐 While deviations from a given target are seen in compensated graphs, it's important to view them in context—what seems off might actually contribute to desirable audio characteristics.

  • 🎚️ Raw measurements provide a more reliable insight into how a headphone truly performs, reflecting its design and production intentions without adjustments.

  • Discussion on compensated graphs and how they should align to a flat line if matching the target perfectly.

02:30 Implications of Graph Interpretation:

  • The challenges of using compensated graphs without knowing the underlying target.
  • Tips on interpreting raw frequency responses and understanding typical desired curves, such as the rise around 1k Hz.

04:00 Analyzing Examples:

  • Walk through specific headphones like the Sennheiser HD6XX, explaining their graph representations and typical acoustic patterns.

06:00 Practical Application:

  • The importance of considering personal auditory preference and the discrepancies that might occur due to individual hearing differences or headphone fit.

07:50 Closing Thoughts:

  • Andrew rounds up the session with final advice on using frequency response graphs as a tool rather than a definitive guide, encouraging viewers to also listen and test headphones personally.

❓ FAQ

What is a compensated frequency response graph?

Compensated graphs are altered to match a predefined sound target, usually aiming to show a flat response line when the headphone perfectly matches the target.

Why are raw graphs important for evaluating headphones?

Raw graphs display the headphones' true sound characteristics without any modifications to fit a specific standard, making them vital for assessing the natural sound profile of the headphones.
