The F-35 will be used in Burlington nearly 5,500 times per year — a slower pace than current F-16 flights — and will be significantly louder than F-16s.Houses closest to the airport have been vacated and sold through a Federal Aviation Administration program that buys homes severely affected by noise pollution.The EIS explains the difference between three concepts: sound level, sound intensity, and perceived loudness Here are the numbers and explanation, all from the EIS: Table BR3.2-1 on page BR4-18 of the EIS gives the Lmax for the F-16C and the F-35A Lmax is the maximum sound level for takeoff: Lmax is 94d BA for the F-16 and 115d BA for the F-35, a difference of 21 d BA for landing: Lmax is 73d BA for the F-16 and 95d BA for the F-35, a difference of 22 d BA The second volume of the EIS explains on page C6 that d BA is an adjustment made to the measurement to correspond to the frequency sensitivity of the human ear.
“Computer spies have broken into the Pentagon’s $300 billion Joint Strike Fighter project — the Defense Department’s costliest weapons program ever — according to current and former government officials familiar with the attacks.
Similar incidents have also breached the Air Force’s air-traffic-control system in recent months, these people say. has no single government or military office responsible for cyber security.
The second 10d B of the 21d B is perceived as a doubling from that doubling, or four times louder than the F-16. So we can say “according to the numbers given in the Air Force EIS, the F-35 has a maximum loudness that is more than 4 times louder than maximum loudness of the F-16.” For those also interested in sound intensity, the numerical difference between the F-16 and F-35 is much greater.
The formula for the difference in sound level in d B = 10 x log (A1/A2) where A1 and A2 are the sound intensities (also called sound amplitudes and sound pressures).
On page C-6 of the EIS we read: “A change in sound level of about 10d B is usually perceived by the average person as a doubling (or halving) of the sound’s loudness, and this relation holds true for loud sounds and for quieter sounds.” The F-35 has a maximum sound level that is 21d BA higher on takeoff and 22d BA higher on landing.
Under that rule of thumb provided in the EIS we can consider that the first 10d B of the 21d B is perceived as a doubling of the loudness from the F-16 level.
Of approximately 500 troops in the vicinity of the accident, 23 were killed and over 80 were injured. id=19940323-2 An F-16 crashed into an occupied area of Hengelo, Netherlands.
Fortunately there were no injures and the pilot ejected safely.
Sound level, sound intensity, and loudness are explained in the Air Force draft Environmental Impact Statement (EIS).
The bottom line is, according to figures in the EIS, the maximum loudness of the F-35 is more than four times louder than the the maximum loudness of the F-16 both at takeoff and landing.
The F-35, among many reasons to oppose it, is super loud, will be harmful to our communities, schools and property values, is a record-setting waste of money when we need real jobs programs, and is an aggressive instrument of war. Its noise is so high that more affordable houses in the historic neighborhood near the airport will have to be torn down.
