First of all, it seems that übertragende Bedeutung is sometimes used synonymously with übertragene Bedeutung - metaphorical, figurative.

Secondly, I don't know how to deal with "Begriff" here, since we're talking about auditory perception. Can concepts be perceived aurally?

In terms of auditory perception, he seems that he still has communication problems on the level of the conveyed meaning of ideas/terms/concepts/signs.
Finally, the problem of conveyed meanings is addressed. The conveyed meaning of an utterance is the information that is communicated by means of the utterance without being literally said. We defend the distinction between literal and conveyed meaning and account for the relation between conveyed meaning, in particular the conveyed meaning which is associated with so-called indirect speech acts, and literal meaning in terms of a system of defeasible rules of thumb. We show that a simple system of such rules can account for a wide range of conveyed meanings.

The perception of sound plays an essential part in the lives of most individuals. Hearing conversation or enjoying music provide some obvious examples. Other examples are less obvious, such as, the effect of music in film, or the emotional meaning conveyed by intonation of the voice. Our laboratory research is aimed at understanding how humans recognize, remember, and interpret these meaningful sound patterns.

In close collaboration with the Auditory System Quality group, the influence of acoustic parameters on the conveyed meaning of auditory signs is being investigated and guidelines for the improved design of auditory signs are being developed.
