Definition: Dissociative stupor is diagnosed on the basis of a profound diminution or absence of voluntary movement and normal responsiveness to external stimuli such as light, noise, and touch, but examination and investigation reveal no evidence of a physical cause. In addition, there is positive evidence of psychogenic causation in the form of recent stressful events or problems.

‘marginally compliant aircraft’ means aircraft which are certified in accordance with limits laid down in Volume 1, Part II, Chapter 3 of Annex 16 to the Convention on International Civil Aviation signed on 7 December 1944 (the Chicago Convention) by a cumulative margin of less than 8 EPNdB (Effective Perceived Noise in Decibels) during a transitional period ending on 14 June 2020, and by a cumulative margin of less than 10 EPNdB following the end of that transitional period, whereby the cumulative margin is the figure expressed in EPNdB obtained by adding the individual margins (i.e. the differences between the certificated noise level ...[+++]and the maximum permitted noise level) at each of the three reference noise measurement points defined in Volume 1, Part II, Chapter 3 of Annex 16 to the Chicago Convention.

This recommendation will serve as a basis for revision of the mandatory limit values in the context of the ongoing TSI revision process, which will also take into account the results of the recent measurement campaign of noise emitted by high-speed rail vehicles on a reference track, co-financed by the Commission.

In the past, Community measures to reduce noise from these equipment consisted of directives laying down requirements relating to permissible noise levels, noise level marking affixed on the equipment and noise measurement standards.
