Virgin Atlantic Hires Whisper Coach
Thursday, 01 March 2012 | by Pat's Picks

There’s a new requirement for flight attendants serving first-class passengers on Virgin Atlantic: they must be able to whisper. The airline has actually hired a “whispering coach” because what first-class passengers really want on a flight is silence. Apparently, anything between 20 to 30 decibels in considered an appropriate whisper.
