EyeMorphometer Low Noise Certification
AC 36-4D
It is applicable for noise certification of normal, utility, acrobatic, commuter and transport category airplanes and normal and transport category rotorcraft as defined in part 21.
Aircraft Noise Certification Test
Our solution is approved for aircraft noise certification. As global air travel grows, so does the concern for noise around airports. This leads to increasingly strict legislation of exterior noise.
Reduction of Noise at Source
The database is intended to be a general source of information to the public on certification noise levels for each aeroplane type as provided by certification authorities.
Application of Noise Certification Regulations within Conceptual
Specific noise sources with a dominating impact on the certification noise levels can be identified, and promising additional low-noise measures can be applied within the conceptual design
eCFR :: 14 CFR Part 36 -
A36.4.1.1 The basic element for noise certification criteria is the noise evaluation measure known as effective perceived noise level, EPNL, in units of EPNdB, which is a single number
Noise level certification, how to select the right standard?
Anyone who wants to sell certain equipment on the European market has to measure its emitted sound power level and stay below the specified target set by national legislation.
