Sonification is defined as the use of non-speech audio to extract information from data and it represents the sound analogue to graphical visualization. The method is applied in several disciplines from economy to medicine to physics. Sonification might also help in analyzing spectra of quantum particles. It could assist, together with graphical display, to distinguish between different models or to examine the behavior of physical observables as a function of parameters like temperature and couplings. In order to demonstrate the methodology a graphical user interface was developed for listening, e.g., to different level orderings in baryon spectra obtained from one-gluon or Goldstone-boson-exchange dynamics. We further applied the technique to quantum chromodynamics on the lattice and analyzed the eigenvalues of the Dirac operator as a function of temperature over the phase transition from confinement to the quark-gluon plasma. The studies are also part of the development of program packages for audio browsing within the interdisciplinary research project SonEnvir (http://sonenvir.at/).
