Mismatch Negativity Using Frequency Difference in Healthy Young Adults: Latency and Amplitude
Korean Journal of Clinical Laboratory Science, 2020 Latency and amplitude are the measurement parameters of mismatch negativity (MMN). The values of the parameters vary sensitively with the stimulus paradigm. A paradigm using the frequency difference of sounds for the MMN study is well known.

Aspects of Electron Acoustic Wave Physics in Laser Backscatter from Plasmas [PDF]
, 2006 Recent experimental results from the Trident laser confirm the importance of kinetic effects in determining laser reflectivities at high intensities. Examples observed include scattering from low frequency electron acoustic waves (EAWs), and the first few stages of a cascade towards turbulence through the Langmuir decay instability.

Highly-coherent stimulated phonon oscillations in a multi-core optical fiber [PDF]
H. H. Diamandi, Y. London, G. Bashan, A. Bergman, and A. Zadok,
"Highly-coherent stimulated phonon oscillations in a multi-core optical
fibers," Scientific Reports 8, 9514 (2018), 2018 Opto-mechanical oscillators that generate coherent acoustic waves are drawing much interest, in both fundamental research and applications. Narrowband oscillations can be obtained through the introduction of feedback to the acoustic wave. Most previous realizations of this concept, sometimes referred to as "phonon lasers", relied on radiation pressure ...
