Test sequence predicts listener headphone preference using Harman model

BOSTON, MA. Listen Inc. has created a new SoundCheck test sequence that predicts listener preference of headphones based on statistical models developed by Sean Olive, Todd Welti, and Omid Khonsaripour of Harman International.

The sequence measures the headphone in SoundCheck and saves the results to an Excel template. Within Excel, a Predicted Preference Score on a scale of 0 to 100 is calculated based on the Harman Target Response Curve. The calculation involves subtracting the target curve from an average of the headphone left/right response to obtain an error curve and analyzing this curve (standard deviation, slope and average) to calculate the score.

The model includes in-ear, on-ear and over-ear headphones, with the user prompted to select the appropriate type when running the sequence.

The sequence also provides the option to recall data rather than making a measurement, which saves time for engineers who already have large quantities of saved data and enables historical comparison with obsolete products.

The sequence is flexible and easy to customize for specific requirements. It can be downloaded free from Listen’s website:
