Unfortunately this demo works only with some browsers. The sound sample should be listened by headphones (this is binaural recording) and to keep compatibility with many systems it is down-sampled (wav, 44.1kHz). There is a link to a aif-format sound file in this page.

The following sound sample is recorded by an artificial head in a cabinet of a mobile work machine.
You can adjust the volume by this slide
