Wow, I hope you live in a remote area!
Can you still hear, btw?
Very well, thanks for asking.
Dynamic range can be extreme without causing any hearing damage, while listening to something that is consistently loud (even at low volumes) that has a small dynamic range, bandwidth limiting, severe phase distortion, poor coherency and slow rise times (oops, I just described CD playback
) can be detrimental to your hearing even in low doses over time.
Listening to iPOD/MP3 headsets at even 88 to 95 dbSPL can cause permanent irreversible hearing damage in a relatively short period of time and is well documented.
Unfortunately, the bulk of live music today is being reinforced by low quality switching amplification and the levels of intermodulation distortion that people are exposed to is incredible. The last two concerts I attended were horrible and the artists felt they needed to keep the volume level consistently at or above the threshold of pain from the first note to the final "THANK YOOOUUUU" . . .
I enjoy loud music as long as there are some dynamics to allow you to maintain some perception of what "loud" actually is . . . When everything is played at a consistent 125 db or so, it's just irritating.
