Building the Dummy Head

Building the dummy head binaural microphone in stages:

Removing the styrofoam ears to attach the silicon rubber ears The styrofoam ears were removed in order to glue the silicon rubber ears, and a hole was bored in between the ear slots to back of the head for the lavalier mic to pass through ( as an ear canal).

The precast silicon ears were precisely glued with the lavalier mics passed through the sides of the styrofoam dummy head using gorilla glue.

The audio signal from two lavalier omnidirectional microphones is carried via a tiny 3.5mm connection, which connects to an XLR converter. An audio interface receives both the right and left channel signals (Input 1 and 2).

Ableton Live 10 Suite was utilised as the DAW (Digital Audio Workstation) for this project. Then, in the DAW, create two audio channels for Input 1 and 2. Select both external inputs on each audio channel to 1/2 and you should now be able to receive and monitor audio signals from both inputs 1 and 2 simultaneously. 

And now you can experience the binaural effect while listening on both mics simultaneously on the constructed dummy head.
