Ultrasonic experiments are performed on large scale atomic and molecular aggregates in a condensed matter channel. Monochromatic-modulated Gaussian stress pulses are launched into the channel and monitored. Confined by the channel geometry, these pulses are accurately described by a 5-parameter Harmonic-Gaussian template, encapsulating corpuscular and wave-like properties (compatible with Louis de Broglie’s particle-wave duality statement) and identified as phonons.  Hence this template serves as an analytical framework for a non-linear regress-ion analysis, concurrently the 5 parameters above, allowing experimental-uncertainty measurements. Results reveal a high degree of combined accuracy, challenging Heisenberg’s Uncertainty Principle. A critical comparison with nuclear γ-ray photons is also presented.
