The only thing I notice is more powerful stereos in cars. And hip-hop emphasizes the bass much more than the classic rock of the last generation.
Unless I am mistaken, the mid-range and high notes at high volume are much more damaging to the ears than the bass.
I used to listen to music LOUD. Lots of concerts (I remember going to see Ted Nugent about every other week in Winterland,SF and generally sitting on the stage right in front of the speakers).
Well, I started to lose my hearing. It was gradual but noticeable. However, there is hope with acupuncture. After 1 year of treatment by a master acupuncturist, my hearing has completely regenerated.
