Imagine how you would feel if the gravity of the earth would be ten times stronger than it is now. Your feet feel as if they are stuck in ten ton concrete. Your hands constantly seem to reach towards the ground. Your shoulders feel so heavy that you feel like laughing at Jesus' painful facial expression while he is carrying something ridiculous like a cross. Even if you make the biggest effort, you can't even take a step forward. Well, if it is possible for you to imagine something like that, then you might have an idea about the sound of Earth.
