LIESE-Muffler Systems for Light Aircraft                                        Small, light and effective!                                               No loss of Power!                            Certified by german LBA and EASA Our new Silencer system uses a totally new principle of noise reduction without any moving parts or loose damping materials. The silencers are really small and fit inside existing mufflers of most General Aviation Aircraft, f.i. Cessna 152, -172, -182 and -210. For aircraft without mufflers of suitable diameter we have developed small endpipe slilencers, f.i. Cessna-150, Piper PA-28, PA-38 and Mooney M-20. The additional weight due to our silencer typically is less then 2 lbs. With the LIESE-Silencer we meet the strict german noise limits and in most cases achieve noise levels of 5 to 6 dB(A) below the german limit. Some examples of measured noise levels with LIESE-Silencer ( Annex 16, Chapter X ): Aircraft Type      Meas. Noise Level     German Noise Limit        ICAO/EASA Noise Limit -------------------------------------------------------------------------------------------------------- Cessna-150-M        66,1 dB(A)                  71,8 dB(A)                   73,7 dB(A) Cessna-172-N        70,1 dB(A)                  77,2 dB(A)                   83,8 dB(A) Cessna-210-F        78,6 dB(A)                   85,0 dB(A)                  88,0 dB(A) Piper PA-28-181   74,1 dB(A)                   79,2 dB(A)                  85,3 dB(A) Piper PA-38          67,3 dB(A)                   72,4 dB(A)                  79,3 dB(A) --------------------------------------------------------------------------------------------------------- We are holding more than 70 EMZ’s ( german STC’s ) for the most common  types of General Aviation Aircraft with more than 350 certified noise  values for different Models, Engines and Propellers. Some types of A/C we can offer LBA/EASA-certified LIESE-Silencer-Systems. Outside EASA the approval of our LBA/EASA certifications depends on the local regulations of each country.
