When assembling a binaural head, ears are needed.

Its is possible to order silicone one online, usualy at a cost above 50€, but 3D printed ears can be a low cost an practical solution when a 3D printer is available.

The material used with 3D printer, PLA or ABS, lack the flexibility of the silicon or natural ear tissue, but it give a decent result for the price and time involved.

Recently, attempts where made at Locus Sonus to design original ears. They had to have the distinctive shape required to produce the binaural effect, like the concha, de depression in the ear that allow for vertical localisation of the sound due to a frequency cancellation effect know as the pinnal knotch. Thet also had to neutral, not looking like they originaly belong to someone. The focus is then mode on the fonction of the ear than on the shape.
And, they had to be 3D printing friendly.

A set of ears ready for testing.

We initialy build our binaural head using ears dowloaded from thingiverse

The first attempt was a sketchup modeling from pictures of an actual ear. It is a bit small, and the angle is not quite right. In result, the binaural feeling was a bit weak.
The STL file are available for right and left ear.
