Airplanes landing at Waypoint will only fly over county land

Uh-huh, sure thing. And all the planes will be extra quiet. We’ve put together this chart to show the relative decibel levels of various loud sports machines. CFS family members own, and plan to attract others who own toys such as airplanes, 4-wheelers, snowmobiles, and Miami-style powerboats, to the Bayfield peninsula for our listening pleasure.

You will note that permanent hearing loss occurs from noises louder than 85 decibels. Many of those using these loud toys will be wearing ear protection, but you won’t. Also note, powerboats, ATVs, and jackhammers will not fly over your house, but hundreds of airplanes will.

Decibels Typical everyday example
10 dB Rustling or falling leaves
50 dB Louder conversation
60 dB Quiet traffic noise
70 dB Louder traffic
70 – 90 dB ATVs. Noise varies by year of manufacture and exhaust system
85 dB 8 hours of exposure to any noise above 85 dB can cause hearing loss
86 dB Legal limit for snowmobile decibel levels
86 dB Legal limit for powerboat decibel levels
88 dB Propeller plane flyover at 1000 ft
100 dB Hearing loss after approximately 15 minutes
100 dB Jackhammer (pneumatic drill) at close range
101 dB Typical business class Lear jet on approach
103 dB Typical business class Lear jet at flyover at 1000 ft
120 dB Threshold of pain. Hearing damage after very brief exposure


Bayfield County has a noise ordinance for ATVs and snowmobiles, but not for airplanes. The DNR has a noise ordinance for boats, but not for airplanes. There is currently no legal minimum level for overflights. Planes can be as loud as they want, they can be as low as they want, and they can legally disrupt your Apostle Islands’ vacation experience. There are no laws to protect you.

The time to speak up against the noise is now, before the “Last Best Place in Wisconsin” is sold to the highest bidder.

Lets not forget the approach to the new airport. Airplanes need to land into the wind. That's why different neighborhoods get the noise barrage on different days near large airports. Given the prevailing westerlies during much of the year, that would mean that these jets make their approach over the Apostle Islands. That would be really nice fishing, paddling, or sailing on a jet approach path. Stupid. Really, really stupid.
