Resumé

We carry out a study to investigate how naïve (non-audio-experts)
users understand the concept of sound directivity. This was done in
the context of loudspeaker reproduction of sound fields with the
purpose being to discover how such acoustical phenomena can best
be explained to users. We investigated the mental models of 20
participants via an interview-based approach, in which we asked
participants to draw and explain how they understood directivity,
only providing them with minimal prior information. The
interviews and drawings were analysed and mental models were
extracted. Our analysis showed the models could be categorized
into three General Mental Model Types (GMMTs): Direction of
Sound, Area with Sound, and Sound Waves. These GMMTs were
then used to build a 3-level combined model that also contains
observations of what each GMMT is suitable for when trying to e.g.
explain or illustrate loudspeaker directivity to non-expert users.
These guidelines can be useful for designing visual representations
to help explain loudspeaker directivity to non-expert users, and
could be used for visualising further complex acoustical concepts.
