  1. HINT: Hearing in Noise Test, dB(A): A-weighted decibel, SPL: sound pressure level, Neutral: pinna in neutral position, Forward: pinna in forward position, Noise 45°: noise presented at 45 degrees left from center forward, Noise 135°: noise presented at 135 degrees left from center forward, Δ: change in HINT between pinna neutral and pinna forward.
