During standard operations, aircraft engines make loud noises that can be heard from far away. This continual and often disruptive aircraft noise can cause several issues for those living and working nearby. One primary concern is the health status of airfield employees who are constantly exposed to the loud sound of engines cutting off or surpassing their capping speed during takeoff/landing procedures.
Environmental noise has been a significant point of debate in recent years. There are several factors that determine the level of aircraft noise, such as the model of aircraft and the type of engines used for each flight, whether the aircraft is taking off or landing, how quickly each plane ascends and descends, and whether the aircraft is operating at full power or partial power.
While noise cannot ever be fully eliminated for obvious reasons, there are many options and safety precautions available to manage and reduce loud noises that emanate from aircraft, which will improve the quality of residents' lives and reduce the negative impact on company employees working at or nearby airports.
Aircraft Jet Blast Protection
Jet blast deflectors are an essential component of any airport that continuously experiences heavy traffic. They protect infrastructure, personnel, and vehicle movements by perting an aircraft’s jet wake airflow during airfield maneuvers and they can be used during ground run-ups to reduce jet engine blast or wake to safe levels. In addition, jet blast deflectors are crucial for keeping the noise level produced by an aircraft under control. They come in many different designs depending on an engine’s configuration, available space, and operation requirements of the airport. They also control engine efflux, benefitting even the smallest components by protecting an area of limited space and enhancing aircraft movement.
Though there are several reasons for aircraft noise, aircraft engine maintenance testing is a primary source of noise emission. The ground run-up enclosure (GRE) design is innovative in that it contains noise while guarding against jet blasts. Invented by aircraft manufacturers, these enclosures are high-performing and aerodynamically designed. They reduce overall noise levels and mitigate inpidual sources. The GRE can be used either after production or during maintenance activities, making it an essential tool in one’s arsenal. The most crucial part of its design is enhancing aeroacoustic performances as well as crosswind and tailwind operation.
Conclusion
Aircraft noise is defined as the noise produced by the aircraft during flight, and it has several negative impacts and health effects, such as leading to sleep disorders and cardiovascular diseases. The day-night sound level (DNL) noise metric is helpful to reflect how much environmental noise you are exposed to over 24 hours. This expression considers what people will experience during their daytime and nighttime periods, which allows for an accurate representation of overall compliance with aviation regulations. The Federal Aviation Administration (FAA) has adopted DNL 65 dBA as the threshold for significant noise exposure.
