The Commands page has an answer to your question and the example used for the /playsound command is exactly the sound you are looking for!

To directly answer your question: Yes, there is a file for it. It's found in the mod file at. The first text for each sound (the one separated by dots) is the ID you have to use ingame. Don't forget the  prefix.
