I reported previously (in 2011) about the discovery of a garment bell that a High Priest would have worn on his robes when administering in the Temple’s Holy of Holies.  The sound of all 72 bells has now been recreated, so you can hear exactly what it would have sounded like on Yom Kippur 3000 years ago.
