most fast foods contain large amounts of cholesterol chocked ingredients, high starches and refined sugars, all of which are VERY BAD for your hearing. these foods in excess lead to Arteriosclerosis; thickening of the passages and tubes in the ear so there is no vibration; excess earwax or other obstructions; mucous clogs; infection or inflammation; swelling; congestion and chronic bronchial infections/swollen glands.
Foods that you should be eating include lots of vegetable proteins, whole grains, nuts, seeds and sprouts. Garlic is excellent for clearing head passages. Food rich in Beta Carotene help against tinnitus. Vitamin E also promotes good hearing.
You can also do ear exercises to help loosen earwax, this includes massaging your neck, ears and temples. Pull ear lobes-top, front and back to clear ear passages.
Above all, try not to blow out your ear drums testing your wicked new amp/IEM setup!
hope this is helpful for some of you and if you have any more tips to promote good hearing, please share
