How is the noise sheilding provided by the fuselage when the engines are mounted at the rear end of the aircraft ? for example-SAX 40

Noise levels at different parts of the aircraft will vary depending on engine location.
Rear-mounted engines on aircraft have a significant impact on reducing noise levels for passengers and communities near airports. By placing the engines at the back of the aircraft, the noise produced by the engines is directed away from the ground, resulting in quieter takeoffs and landings.
There are various types of engines used in aircraft, but high bypass ratio turbofan engines are known to be the most effective at noise shielding. These engines have a large fan at the front that helps to reduce noise levels by increasing the volume of air that bypasses the engine core.
While rear-mounted engines are beneficial for noise shielding, they do have some impact on the performance of the aircraft. The weight and balance of the aircraft must be carefully managed to ensure that the rear-mounted engines do not affect the stability and handling of the aircraft.
One potential drawback of rear-mounted engines is the increased risk of damage in the event of a bird strike. As the engines are located at the back of the aircraft, they are more vulnerable to bird strikes compared to engines mounted under the wings.
Yes, there is ongoing research and development in this area, with a focus on improving the design and technology of rear-mounted engines to further reduce noise levels. Additionally, advancements in materials and engine technology may also contribute to improved noise shielding in the future.
