Which factors influence JND in music?

• A. Frequency differences, loudness differences, and listener training
• B. Only frequency differences
• C. Only tempo differences
• D. Only harmonic complexity

Answer: (A)

Just noticeable difference in music is about the smallest change a listener can detect. Across common listening tasks, three factors shape these thresholds: differences in frequency (pitch), differences in loudness (intensity), and the listener’s training or experience. Pitch discrimination thresholds depend on frequency and context, and musical training can sharpen the ability to detect small pitch changes by improving how we encode harmonic relationships. Loudness discrimination also follows perceptual scaling, with sensitivity that can be enhanced by experience and listening practice. Because all three influence how finely we notice changes, including frequency differences, loudness differences, and listener training provides the most complete account of JND in music. Tempo differences and harmonic complexity relate to other aspects of perception (timing and timbre), but they don’t capture the general determinants of JND across the main perceptual dimensions.
