The sound of a helicopter has never been described as soothing.
The noise output of a helicopter at a distance of 100 feet has been calculated
at 105 decibels-five decibels higher than a jackhammer.
Fortunately, Leading Edge Aviation-the Bend company that wants to
start offering helicopter tours above Crater Lake National Park-doesn't propose
buzzing the lake at 100 feet; it says its choppers will fly no lower than 1,000
feet.
But the whumpa-whumpa-whumpa of churning rotor blades, whether at 100
feet or 1,000, is not a sound that belongs at Crater Lake, Oregon's only
national park and a place where people go to see natural beauty and experience
(relative) peace and quiet.
Even at 1,000 feet or more, as anybody who's heard one of the Air
Link helicopters zoom overhead can attest, the sound of a helicopter is
impossible to ignore. Travis Warthen, a vice president for Leading Edge, told
The Oregonian that an RV or (in winter) a snowmobile driving along the rim road
would be louder than one of his 650-hp Bell helicopters. Maybe so, but that
seems like a weak excuse to add another element to the noise mix.
