What do you do for work and how often are you exposed to high SPL sounds? If you insist on keeping the audio level high, you have no choice but to lose what's left of your hearing ability. The fact that the volume control goes higher than necessary doesn't mean it has to be set at maximum.
If you have worked in loud places without any hearing protection, you need to ask yourself if you ever wondered about hearing loss and if your employer(s) have offered protection but you refused, well.....
If your employers never offered, did they post or hand out OSHA regulations? That's mandatory.
The medical field DOES understand ears and hearing- it's your doctors who are dropping the ball. Did they inspect your ears? What did they see? I had slight pain and loss of upper mid/high frequencies in one ear and upon inspection, it was found that I had wax buildup. Once I flushed it, my hearing is fine.
Car stereos and cars are a big factor in this, as is just being in traffic. Driving with your window open is another good way to lose hearing- the noise level is definitely a factor. If you use power tools, especially impact drivers, you MUST use hearing protection. Do you swing a hammer? Ditto- This Old House had an episode with someone from OSHA where they measured the SPL from using a regular hammer and it reached over 130dB- that's more than enough to cause permanent damage. If you're exposed to a narrow band of frequencies, you WILL lose acuity in that range- it's not negotiable.
There's no reason to hit high SPL while watching TV or movies- it's not a contest and if it were, the level should be measured with people out of the area.I have seen videos of idiots measuring the SPL of their car stereos and home theaters, with the meter showing over 140dB. First, that number is highly unlikely because low frequency impacts at that level can disrupt the heart and second, 130dB is the commonly accepted level called 'threshold of pain'. That has been raised by 10dB- used to be that 120dB was the pain threshold but that's now called 'threshold of feeling'.
