Acidity and heartburn with headphones.

Every time I use headphones i get acidity and heartburn immediately or within a day. I have observed it multiple times, so I stopped using headphones completely years ago. Recently after using headphones(unavoidable situation) for few hours it happened again, but this time it kept on hurting my ear for many weeks. And now even listening to tv or people talking loudly I get acidity and heartburn. In last couple of weeks it felt like acidity and heartburn stopped and only my throat hurt after a meal at night mostly. I consulted a ENT, and learnt that it may be LPR(silent reflux). I am taking medication Mucaine gel, calcium-D3 supplements and anti allergies tablet, but it only gave temporary relief. So my question is what exactly is going wrong with me? Why do headphones give me acidity, nausea, vomiting? Am I becoming sensitive to even normal sounds? Is there a name for this condition?
