Minimum Audible Angle measures the smallest discriminable angular change

Evidence

In brief, the outcome measure of this study’s experiment was the Minimum Audible Angle (MAA) in the vertical plane. This is the minimum angular change away from a given reference angle, which can be discriminated in a simulated set-up with sound stimuli presented via headphones. — Dijk, Pim van, Physiology, Psychoacoustics and…, 3052

Categorization

• DEFINE: Defines MAA as the smallest angular change from a reference that can be discriminated, a key psychoacoustic measure.
• corroborated: 3 independent passages support this claim — Dijk, Pim van, Physiology, Psychoacoustics and…, 3052
• XREF: connects to: The minimum audible angle quantifies the just-detectable change in sound source position; The just-noticeable difference quantifies the smallest audible change in a sound; Down-shifted Weinrich cues improve MAA in hearing-impaired listeners by about ten degrees — Dijk, Pim van, Physiology, Psychoacoustics and…, 3052 (+3 more)
