Collecting sounds

Collecting sounds:  Let us know how you collected the sound.  You may use the iPhone application through the method that is suggested (placing directly on the chest) - or - you may connect any type of microphone or other apparatus to collect your sounds.  If you use a collection method other than placing the iPhone directly onto your chest - we ask that you write a short note about what you did in the body of the email containing the sound file.  

The sound is not returned:  You may not have the sound returned to you.  You will not have control over the sound once it is sent.  The sounds will not be kept in a way to identify you even to the researchers - as such, no one may identify you as the person with the particular sound.
