Instrument Detection

Attentive Tracking
Reference: Buergel, Picinali & Siedenburg (2021)

This demonstration explores the human ability to detect a specific musical instrument within a musical mixtures. It specifically highlights the role of prior knowledge & attention: In the "Target first" condition, hearing the isolated instrument creates a mental template (auditory schema) that helps the listener track the instrument within the mixture. In the "Mixture first" condition, this prior guidance is missing, making detection more dependend on the instrument's ability to stand out of the mixture. By adjusting the Target-Level Ratio, you can experience how signal intensity and presentation order interact to influence your detection accuracy.

Note: This section is an approximation for illustration. It is not the original experimental setup described in the reference but serves to provide a feel for the psychoacoustic effects at play.
▼ How to
  1. Press either "Target first" or "Mixture first" to play one stimulus.
  2. Decide whether the cued target was included in the mixture.
  3. Results are plotted as Squares (Target first) or Circles (Mixture first).
  4. Repeat as often as you like.
