With the highest priority of climate change shortly aircraft noise in/around airports is still considered as important but with the priority global GHG emissions. The balanced approach realized during the last few decades by ICAO provided a huge reduction of noise exposure around airports worldwide and several impacted people by noise. The aviation sector is expected to triple the air traffic (taking in mind only the development of usual air traffic without the contribution of the new Urban Air Mobility and other Advanced Air Mobility approaches) through 2050 and the benefits of a balanced approach must not be diminished. It means that noise reduction technologies will develop in the same way as during previous decades for new designs of aircraft so as for new low-noise operation procedures. If to look at new supersonic aircraft future technologies are also considered in mostly traditional development of noise reduction in engines and airframes (as considered now by the EU SENECA project). The EU concept of environmentally friendly aviation by 2050 (compared to 2000) provides for the use of new technologies for aircraft designs still in operation: to reduce the perceived aircraft noise by 65%. Achieving these goals requires evolutionary changes in aircraft design, improved aerodynamic configurations, and the use of innovative engines. Taking in mind the highest priority for climate change goals globally and in particular for the aviation sector the revolutionary aircraft designs are subject to noise control also. The existing taxonomy of noise sources and roadmaps for their reduction should be widened to cover the new designs and technologies. The acoustic performances of radically new innovative aircraft concepts should be in line with evolutionary achievements. The electrification of aircraft propulsion promises a significant reduction of aviation emissions and progress toward strategic goals achievement. But their main noise sources like the propellers and airframe dominant sources still need for further improvements to reach the EU strategic goal in perceptive noise. The recommendation for the EU EFACA project relates to the implementation of hybrid electric propulsion technology (combination of gas turbine and electric engines) for propeller-driven regional aircraft must be accompanied by appropriate noise reduction efforts.
