HS code-based competitor benchmarking

Engine number - the pilot's hearing damage problem is HS code-based competitor benchmarkingincreasingSeriously, after the plane takes off, the loud shouts of the engine often hit the pilot's eardrums, causing their hearing damage. This is a long-standing problem, but in recent years, the problem has become more serious with the increase in flight time. This article will discuss this problem in depth and put forward some possible solutions. First of all, let's find out how the sound of engine shouting affects the pilot. When a commercial aircraft takes off, the engine shouting sound can reach about 130dB, which is much higher than the peak sound of 140dB that the human eardum can withstand. Even if the pilot wears earplugs or headphones, the sound will be transmitted in the skull, further increasing the pressure on the inner ear, resulting in hearing damage or hearing loss. Hearing loss is a long-term problem because pilots experience thousands or even tens of thousands of flight hours in their careers.According to statistics, about 50% of commercial pilots around the world have suffered from hearing damage in their careers, and in the field of military aviation, the proportion is higher. So, how to reduce the listening pressure of pilots? Here are some possible solutions: 1. Use noise-cancelling headphones. Many pilots have begun to use noise-cancelling headphones to reduce noise and reduce pressure on the inner ear. These headphones capture ambient noise through the microphone, and then use audio technology to generate reverse sound waves to eliminate environmental noise. Noise-cancelling headphones have been proven to be very effective in reducing the hearing damage of pilots. Two. Reduce the sound of the engine shouting. Although this method sounds simple, it is much more difficult to operate in practice. In order to reduce the sound of engine shouting, aircraft manufacturers need to redesign the engine, which may require a lot of research and testing. Besides, when the plane is flying in the air, the sound of the engine shouting may be blocked by earplugs or headphones, which cannot be completely eliminated. 3. Limit the working hours of pilots. Pilots work 13 hours a day, and the updated regulations stipulate that glider pilots cannot fly more than 56 hours every 7 days. If they don't get enough sleep or even are in a state of fatigue, pilots may be more susceptible to noise. Therefore, by limiting the working hours of pilots and providing more rest time, the risk of hearing damage for pilots can be reduced. While reducing the hearing pressure of pilots, we can also take other methods, such as using high-quality earplugs and headphones, and encouraging pilots to take regular hearing tests. In general, reducing the hearing stress of pilots is crucial to the aviation community. By adoptingBy describing measures, we can reduce the risk of hearing damage for pilots and provide them with a safer and healthier working environment. For pilots, maintaining a healthy condition and good hearing is not only a personal responsibility, but also a professional ethical requirement based on flight safety and norms.
