I don't remember whether it made loud noises at first or not. I've had mine since June of 2010...however...word to the wise...when you are able to eat...try to eat 6 small meals a day. I found that if I wait a long time between meals, or go without lunch and eat an early dinner, boom...sounds like an earthquake. Must be the air build up? Don't know. I remember being very embarrassed at church one Sunday morning
