No.
Yes it is your own.
YOu really need to talk to your doctor or nurse about this as you have not said why you cannot hear a heartbeat.
That is the persons heartbeat. Our hearts beat, constricting and expanding, so that they can pump blood.
Lol, I'm not sure what kind of question this is, but... When you mention listening to 'Rock', you should mean, in this context, any type of loud music. Afterward, when it's not playing, when you hear a heartbeat, obviously it should be your own heartbeat. The reason that you would hear your own heartbeat in this situation would be due to oversensitivity in your ears; adjusting after overexposing your eardrums to loud 'sounds' (the 'rock' music), and thanks to this oversensitivity, you can hear the blood rushing through your ears, and hear your own heartbeat. It's much like being able to hear your heartbeat while in a situation in which your body would be using Adrenaline, since Adrenaline is supposed to heighten your senses, among other things.
Yes, they can. They have the ability to hear the heartbeat of a mouse, so a human heart wouldn't be a problem for them to hear.
