We consider the tunnelling of acoustic waves between two slender tubes through a monomode structure. We give in closed farm the conditions for selective transfer of a single propagating state from one tube to the other, leaving all other neighbor states unaffected. We illustrate the results of this analysis by analytical solutions for a simple structure made out of pieces of slender tubes.
