Directional microphone

For research projects with the aim to gather sound tracks in the field (e. g. IBF Orthoptera) and store them in the internal storage unit of a smartphone a directional microphone is necessary. Currently (in 2012), the head set adapters available for HTC 7 smartphones are not appropriate to connect directional microphones.

In cooperation with Stephan Meßlinger, University of Bayreuth, LS Experimentalphysik V, a technical solution is found to overcome this obstacle.

• For use of directional microphones in the DiversityMobile context users should purchase a standard head set adapter.

• This adapter has to be modified following the description in the connection diagram in relation to the brazing process:
