Ultranarrow-linewidth stimulated Brillouin scattering with fundamental acoustic waves by Wendao Xu, Maxime Zerbib, Arjun Iyer, Kien Phan Huy, Jean-Charles Beugnot, William H. Renninger

“…While interaction strength and linewidth directly affect device performance, most strongly interacting Brillouin systems have linewidths of many MHz, limited by the high frequency of the participating acoustic waves. By engineering Forward Inter-Modal Brillouin interactions to access the Fundamental Acoustic Modes (FIM-FAM), strong Brillouin coupling can be extended over a wide frequency range, including lower frequencies that support significantly narrower linewidths. …”

A New Fundamental Asymmetric Wave Equation and Its Application to Acoustic Wave Propagation by Z. E. Musielak

“…It is shown that among these equations only a new asymmetric wave equation is fundamental. By being fundamental the equation gives the most complete description of propagating waves as it accounts for the Doppler effect, forward and backward waves, and makes the wave speed to be the same in all inertial frames. …”

Valor e variações da freqüência fundamental no choro de dor de recém-nascidos Value and variations of fundamental frequency in newborn pain cry by Anete Branco, Saskia Maria W. Fekete, Lígia Maria S. de Souza Rugolo, Maria Inês Rehder

“…METHODS: emissions of 111 healthy and term newborns were recorded, whose lifetime varied from 24 to 72 hours, during venepuncture procedures. The acoustic analysis was realized with VOXMETRIA 1.1 software, with an extract from the fundamental frequency value and GRAM 5.7, in order to verify the occurrence of fundamental frequency variations such as breaks, double harmonic breaks and higher fundamental frequency. …”
