Sound of crunched paper – volume calibration

In order to get the highest level of realism when listening to nature recordings, I think it is important to set the volume as close to the original sound as possible. Preferred listening volume, in headphones, is a highly individual preference, so the only way to get the correct setting is to perform a calibration.

With  inspiration from the funny sound clip from this page, I got the idea of using things at hand when you are sitting at your desk, namely paper and a pen, to make  well-known sounds at a well known sound level.

Therefore, the following recording is simply made by setting the dummy head with the microphones at a normal head position in front of a work desk (40-50 cm from head to paper). Sitting next to it I produce some sounds; writing with and clicking a pen, wobbling, tearing and crunching a piece of A4 printer  paper. These sound should be possible to reproducible at any desks and thereby allow to adjust the sound level of your headphones accordingly. Having this setting I’m hoping to use this same amplification level for all future sound clips posted here, however it is not yet implemented.

As usual playing the audio at reduced speed exaggerates the drama.
