According to observational data some regions of quiet sun show an excess, or the “emission” of acoustic waves. We propose a mechanism to explain the excess of the emission of acoustic waves based on nonlinear coupling of magnetic flux tube oscillations and the acoustic waves. We also suggest a new approach in the data analysis, which can be called “Raman spectroscopy of p-modes”. This new idea is based on the fact that oscillating flux tubes constructively interfere with the acoustic wave which results in the generation of beat waves with combinational frequencies: the power spectra of scattered waves in addition to main peak will have Stokes and anti-Stokes satellites. Their amplitude and frequency shift reflect the properties and the structure of the observed region.
