I wear ear protection day to day as part of my job. I nearly had to quit (in the early days of my tinnitus) but the ENT ensured me I wouldn't suffer anymore damage as long as I wore ear protection and somehow I continued. Was he lying?
He was repeating what he was taught in medical school. For some bizarre reason, doctors are not taught that the ears of a tinnitus sufferer are more vulnerable than the ears of healthy people. I am pretty sure that this is the case, based on what had happened to me personally, and on numerous cases I read about on this forum.
Having said this, it sounds like you did not get any noticeable spikes after being at work. This is a good sign. My rule of thumb is to listen to the signals from our bodies.
If you can easily find a quieter job, then it would still make sense to quit your current job, though.
Now I have heard someone say 'ear plugs are unreliable' it has made me really paranoid.
I based that statement on the fact that people have been getting spikes following noise exposure.
Also, are ear defenders (the one's that cover up the whole ear) better than earplugs?
They all have a noise reduction rating (NRR). The highest ratings are 29-32 dB. You can wear ear plugs underneath Peltor X5A muffs. By combining two methods of hearing protection, you would be increasing noise reduction by about 5 dB.
I don't think wearing earplugs should be discouraged though imo.
I was trying to convince the other person to not needlessly expose their ears to noise. Of course if one is around noise, the more ear protection one has, the better.
Personally, for the first month after my acoustic trauma I would use a blender and a vacuum cleaner, etc. After I started protecting my ears from moderate noises like that, I began seeing some improvement in my T. Of course it could be just a coincidence.
