DLF, Difference Limen Frequency; RH, Resolved Harmonics; UH, Unresolved Harmonics; PDT, Pitch Discrimination Threshold; PCD, Pitch Change Detection; PDIT, Pitch Direction Threshold. ST, Semitone. Amusics are considered impaired compared to controls when the difference between the groups was significant.
