The following are some advice to prevent tinnitus, meniere's disease and even cataract.
1) Don't keep decayed food (rubbish) at home.
2) anything that will grow large amount of bacterial should throw out of house as soon as possible.
3) Dirty clothing need to wash immediately, don't accumulate inside house few days.
4) Make sure the toilet bowl always has water in it, if the water dry out (log time no pump water), the gas and bacterial from sewage pipe will enter into the room.
5) Carpet (if any) need to be vacuum every day, if carpet dirty it will grow large amount of bacterial.

Large amount of bacterial floating in air in the living room, sleeping room will cause sinus infection.
Sinus infection will make your ears feel blockage (one or both), prolonged sinus infection will causes meniere's disease and tinnitus.
....and even cataract.
Note: the above is what I believe to be true, no source of information (no link to some onlne article) provided.


addition: This one I watch in some TV programe:
It say avoid eating full full before sleep,
because stomach too full will cause stomach acid flow out and into the nose and ear area and this will cause ears feel blockage and meniere's disease and tinnitus too.
