We construct traversable thin-shell wormholes which are asymptotically Ads/dS applying the cut and
paste procedure for the case of an acoustic metric created by a relativistic Bose-Einstein condensate. We
examine several definitions of the flare-out condition along with the violation or not of the energy
conditions for such relativistic geometries. Under reasonable assumptions about the equation of state of the
matter located at the shell, we concentrate on the mechanical stability of wormholes under radial
perturbation preserving the original spherical symmetry. To do so, we consider linearized perturbations
around static solutions. We obtain that dS acoustic wormholes remain stable under radial perturbations as
long as they have small radius; such wormholes with finite radius do not violate the strong/null energy
condition. Besides, we show that stable Ads wormhole satisfy some of the energy conditions whereas
unstable Ads wormhole with large radii violate them.
