I am 58 years young and can tell that my enjoyment of music is diminished if I have been exposed to loud noise during the day, so I include vacuum cleaners, hair dryers, blenders etc in the times to protect hearing. This may seem excessively paranoid but hearing damage accumulates very slowly over the years, while the enjoyment of music increases in value as you get older. Clear hearing is truly a treasure. Besides the loss of ability to hear certain frequencies, ringing of the ears also decreases music enjoyment by destroying that black background. Ringing can be caused by smoking, many medications including asprin as well as loud noise.
Bar81 - I do not understand you comment about bud phones. I use in-the-ear phones while traveling to reduce jet noise and listen a low volume - is this a problem?
