TORRES DEL CASTILLO, G.F.  and  GALINDO LINARES, E.. Hamiltonian structures for the acoustic field. Rev. mex. fis. [online]. 2003, vol.49, n.4, pp.344-347. ISSN 0035-001X.

It is shown that the Hamiltonian structures for the acoustic field obtained by means of the canonical formalism using as field variables the components of the molecular displacements or the variation of the gas density are different and lead to different Poisson brackets. It is shown that by requiring that the values of the Hamiltonians coincide, the Poisson brackets also coincide.
