AS Media - Heart Beat Sound Effect

The brief:

-To find a heartbeat sound effect

Originally we had the idea of making our own heartbeat sound, this would consist of someone vocally making the noise or using percussion to emulate the feeling of a heart beating. However after some discussion and evaluation, we decided it was best to find one as although making our own would work, it would be more effective to get a more realistic one for the context of our film.

After listening to all of the sounds there was a noticeable difference between most of the synthetic ones made and the actual sounds recorded.
