How Does the Measurement Process Work?
Curious to see how your headphones really perform? At CanJam Dallas, you can test them using a standardized process and get concrete data, not just impressions. This section explains how it all works.
Step-by-Step Guide
-
Head and Torso Simulator (HATS) Setup: We use a Head and Torso Simulator (HATS) Type 4128C—a special mannequin with built-in ear and mouth simulators. It mimics the acoustic properties of a real human head and torso, creating a realistic testing environment for your headphones. This ensures the measurements reflect how sound interacts with a listener in real-world conditions. Learn more about the HATS Type 4128C.
-
Measurement Points: Following the ITU-T Rec. P.51 standard, we take measurements at specific points. These points correspond to a rotationally symmetrical artificial mouth, which is slightly different from the HATS. This simply means we’re using a standardized method for consistent results.
-
Data Collection: Once your headphones are on the HATS, we play specific audio signals through them. The HATS “hears” the output and records the data, which we then analyze to determine the frequency response and other acoustic characteristics. It’s like giving your headphones a hearing test! You can find more information about the process and the data collected in the 4128-C documentation.
Ensuring Accurate Data
Reliable results are crucial, so we take several precautions:
-
Calibration: We regularly calibrate the HATS and measurement equipment to maintain accuracy and ensure the data reflects true performance.
-
Environmental Control: We conduct measurements in a controlled environment to minimize outside noise and reflections that could affect the results. This is especially important at a busy event like CanJam.
-
Consistent Testing Conditions: We use the same audio signals and testing conditions for all headphones to ensure comparable results. This allows for fair comparisons and helps you make informed decisions based on the data.
How Do I Interpret My Results?
Reading Frequency Response Graphs
After your headphones are measured, you’ll get a frequency response graph. This graph visually represents how your headphones reproduce sound at different frequencies, from low bass to high treble. Think of it as a sonic fingerprint. A relatively flat line generally indicates accurate sound reproduction, while peaks and dips show where certain frequencies are emphasized or reduced.
Comparing your headphone’s frequency response to established benchmarks can be helpful. For example, the Harman target is a popular reference, representing a sound signature many find pleasing. Remember, there’s no single “perfect” frequency response, as preferences are subjective. It’s more about understanding how the graph reflects what you hear. The measurements you’ll see at CanJam adhere to the IEC 60318-7 standard, ensuring reliable and standardized results for Head and Torso Simulators (HATS).
Understanding HRTF and Other Metrics
Head-Related Transfer Function (HRTF) is key to how we perceive sound through headphones. It describes how our unique head and ear shape affects sound waves before they reach our eardrums.
Measurements at CanJam Dallas use a Head and Torso Simulator (HATS), the Type 4128-C, which mimics the acoustic properties of an average adult human head and torso. This simulator helps create a standardized listening environment for measurements. While the HATS provides a solid reference, your individual HRTF will ultimately shape your listening experience. Keep in mind that the specific measurement points used at CanJam are based on ITU-T Rec. P.51, which uses a rotationally symmetrical artificial mouth, not a HATS. So, comparisons with other measurement setups require careful consideration. Context is key when interpreting these results.
How Can I Use This Data?
