The D510B is a nice omnidirectional microphone. Of course not as good as our ears but it is a good one.
It is thanks to Vicky that it was rediscovered. She had been to a conference and they were using some modern electret condenser AKG gooseneck mics. She mentioned that at some times and some speakers they sounded nice. A search was then done on older AKG gooseneck microphones which led to buying through eBay of D590, D528 and finally D510B which are omni
Our ears seem to respond in an omnidirectional way.
And they do not exhibit proximity bass boost effect. Increase of bass is created by our brain when the intensity gets higher (Fletcher-Munsin curves)
The AKG D510B behave in a similar way and they have a small diaphragm like our eardrums.
Some Pleiades experience exists on the use of electret miniature mics as in-ear microphones but this time it was desired to try moving coil microphones.
Signal path:
AKG D510B used as left ear
- Sony TC-D5 Pro - Sennheiser HD 580
AKG D510B used as right ear
2 AKG ST-3 stands are used.
At the moment the stands as placed back to back (Robe di Kapa) so that when the gooseneck a are bent in an s shape each microphone diaphragm is oriented at a position similar to when each human eardrum should be, (correct orientation, distance between 2 ear's eardrums etc.
At this stage no artificial head or obstacle etc is used.
Sound result is very promising.
There is a sense of 3D.
The Pleiades ticking clock can be heard very clearly from far away.
More experiments needed.
