That is true if you can still hear sounds like the balls in our bearings 
clicking together. Those of us who are acoustically challenged will have 
to ask a younger friend to listen to the balls clicking together.  A 
couple of years ago I was running a marathon while wearing a heart 
monitor.  I had set an alarm to warn me when my heart rate exceeded 155 
beats per minute.  The problem was that I couldn't hear the alarm.  My 
fellow marathoners kept telling me that my heart rate alarm was 
sounding. It was disconcerting to have a guy/gal running next to me say, 
"Your heart monitor is telling you to slow down."  

Sorry about straying from the subject.
