BCT predicts a j₁, ₁ = 350 Hz acoustic environment reduces salivary cortisol by 2. 51% (0. 38 nmol/L) in high-stakes negotiating contexts. Measurable by standard ELISA assay, n=40, double-blind protocol proposed. BCT-optimal negotiating room: 6m × 11. 1m × 3. 3m derived from rₒct and rₜet alone. Predictions #194 and #195. Zero free parameters.
