The FAA’s final rule on civil tiltrotor noise limits and conditions for noise compliance measurement becomes effective March 11. It amends regulations governing noise certification standards and establishes new noise limits and procedures to ensure that noise-reduction technology is incorporated in tiltrotors.
NBAA is welcoming International Civil Aviation Organization (ICAO) committee proposals to limit aircraft emissions and reduce noise levels in the near term. The Committee on Aviation Environmental Protection (CAEP) at ICAO wrapped up three years of work last Thursday with recommendations for creating both a metric and standards for carbon-dioxide emissions, as well as for reducing aircraft noise levels by 2020.
The reintroduced Los Angeles Residential Helicopter Noise Relief Act has little chance of being enacted, according to government information website GovTrack.us. S.208 seeks to force the FAA to impose regulations governing helicopter operations in the Los Angeles area. GovTrack.us estimates that the bill has a 4-percent chance of getting out of committee and a 1-percent chance of being enacted.
The FAA has issued a notice of proposed rulemaking (NPRM) aimed at reducing noise generated by new helicopters and supplemental type certificate (STC) modifications for new helicopters certified under Part 36 (noise standards) of the federal aviation regulations (FARs).
The FAA issued a proposed rule on Tuesday that is aimed at reducing noise generated by new helicopters certified under Part 36 (noise standards) of the FARs. If adopted, the rule would impose standards already adopted by ICAO.
A new noise-cancelling headset introduced in April at the Aircraft Interiors Expo in Hamburg, Germany, is set to find a market in business and private aviation.
Middletown, R.I.-based Avid claims the headset “effectively reduces environmental external noise by 85 percent with a 20-decibel maximum noise attenuation.” Forty-millimeter speakers, said an Avid spokeswoman, “ensure crisp, clear sound and well defined bass.”
Less than two weeks before California’s June 5 primary election, some federal lawmakers in the state are again making helicopter noise in the Los Angeles area a campaign issue. In a letter sent yesterday to U.S. Transportation Secretary Ray LaHood, seven members from California’s congressional delegation are urging him to jump-start the public comment period of the FAA rulemaking process.
In an age when general aviation airports are under attack as sources of unwanted noise, Cannes-Mandelieu Airport on France’s Mediterranean coast has reached an accommodation with its neighbors. Just four years ago Côte d’Azur residents were threatening to shut the airport down.
Cannes-Mandelieu Airport has apparently reached an accommodation with its neighbors, who threatened to shut down the airport permanently four years ago. According to Umberto Vallino, marketing and statistics manager for the airport, the key is a noise-abatement effort launched in April using a computer program developed by A-Tech Acoustic Technologies of Brussels, Belgium.
Smac Aero of Toulon, France, continues to develop new technology aimed at reducing aircraft cabin noise and promoted its full line of noise-reduction technology in Cannes, France.
Among the latest items is the SmacBarrier, an acoustic layer designed to reduce the transmission of sound generated around window trim panels, flooring and ceiling panels.
Also fresh off the development line is SmacFoam, specifically created to reduce sound transmission and provide sound absorption in smaller, confined spaces.
