A browser-based listening experiment investigating how the time difference (ITDG) and level ratio between stage direct sound and PA-reinforced sound affect auditory localization judgments in a simulated concert hall.
- 9 stimulus conditions: ITDG (0 / 20 / 40 ms) × level ratio (−6 / 0 / +6 dB)
- Stimuli rendered with binaural room impulse responses (BRIR)
- Reference stimulus: direct path only
- 3 evaluation items per condition
- Q1 Clarity of sound image direction
- Q2 Timbral naturalness
- Q3 Sound image stability
- 3 repeated sets, randomized presentation order within each set
- Left/right channel confirmation before the session
- Playback device (headphone / earphone) reporting
- Repeated presentation to check response consistency
