It does not exist in Spanish. I was going to recommend a visit to rustic, but this mistake really comes from another like 10060;custico. [Let us clarify that acoustic ("relative to audible sound") has its origin in the Greek 945; 954; 959; 965; 969; ( ákouo "to hear", and more precisely "to hear") , but there is no negative prefix there. And if we are to trust the linguists who -for the most part- support the existence of a proto-Indo-European language, it would be quite the opposite, because it should be formed by the union of *h 8322;e 7729;- ( reinforcement prefix ) *h 8322; 7763;ws ( "perceiving") . ]
* Only one "like" per meaning and day, the more "likes" the meaning will appear higher in the list
