Hello guys! Two weeks ago I made a post regarding precautions around flights. I got home 1,5 week ago and noticed that my T have increased in volume since I got home. During flight I used ear plugs and NC headphones (I never used NC before and only used it during flights, no music at all) and it seemed to cancel a lot of the engine sound out. I was at a work conference so the volume of all the people gathering together at dinners etc was quite loud, hitting 75-80 db, I used ear plugs the whole time of course. A lot of times where we had optional events I would go back to my room to avoid the loud noises in the bar etc. So I really took care of my ears to not get exposed when not needed to. However, I couldn't escape everything and my ears did have to sit through a few hours everyday with loud noises. I cannot understand why my T have increased, I didn't use headphones to listen to music, try to avoid loud places when I could and had my earplugs in when it was loud and protected my ears during flights. The only thing I can think about is that I didn't use my NC headphones too much on the way back since it emitted a really annoying high pitch sound, I guess it was just a mix of my own T amped up by the faint noise in the headphones) but still had my ear plugs in. It was not loud enough to make me anxious (I usually are easily). Maybe I didn't have my plugs fitted perfectly? It is the same that I use everyday and I think they work fine and have not had any problem with them so far. Maybe I am just grasping after explanation, but I don't know why it is louder? Worst is in the mornings since I think about it a lot, during the day I tend to forget about it but it is still clear that the T is louder. Is it just temporary? I have had some sore back and neck pain on and off, got a massage yesterday to try to relieve it. Any advice would be appreciated.
