• Concept of differential sensitivity, just noticeable difference
• Weber’s fraction
• Intensity discrimination
• Frequency discrimination
• Duration discrimination and temporal resolution
• Applications of jnd’s
• Magnitude estimation and production
• Loudness – equal loudness level contours and its application
• Loudness scales – sone, phone, Steven’s power law
• Pitch- scales of pitch
