62. Notes that in Italy the broadcasting system has been operating in extralegal circumstances for decades, as repeatedly recognised by the Constitutional Court, and in the face of which the efforts of the ordinary legislator and the competent institutions have proved ineffective in re-establishing a legal regime; RAI and Mediaset each continue to control three terrestrial analogue television broadcasters, despite the fact that the Constitutional Court in its judgement No 420 of 1994 has ruled it impermissible for one and the same entity to broadcast over 20% of the television programmes transmitted domestically on terrestrial frequencies (i.e. more than two ...[+++] programmes) and has found the regulatory regime under Law No 223/90 to be contrary to the Italian Constitution, despite being a 'transitional regime'; nor did Law No 249/97 (establishing the Communications Guarantee Authority and rules on telecommunication and radio and television systems) abide by the prescriptions of the Constitutional Court which, in its judgement 466/02, declared the constitutional illegitimacy of Article 3(7) thereof, 'insofar as it does not provide for the establishing of a hard-and-fast deadline, in any event not exceeding 31 December 2003, by which the programmes transmitted by broadcasters exceeding the limits referred to in paragraph 6 of Article 3 must be broadcast exclusively via satellite or via cable';

The national rules in force on ownership of communications media (licensing systems, allocation of frequencies, audience thresholds, capital participation, etc.) should therefore be extended to the new digital broadcasting services (terrestrial, satellite and cable) in order to overcome any danger of abuse involving concentrations.

a. Vibration test systems employing feedback or closed loop techniques and incorporating a digital controller, capable of vibrating a system at 10 g rms or more over the entire range 20 Hz to 2000 Hz and imparting forces of 50 kN, measured 'bare table', or greater;

c. Flight control servo valves designed or modified for the systems specified in 7A116.a. or 7A116.b., and designed or modified to operate in a vibration environment of more than 10 g rms over the entire range between 20 Hz and 2 kHz.

The assessment of the level of exposure to vibration is based on the calculation of daily exposure A(8) expressed as equivalent continuous acceleration over an eight-hour period, calculated as the highest (rms) value, or the highest vibration dose value (VDV) of the frequency-weighted accelerations, determined on three orthogonal axes (1,4awx, 1,4awy, awz for a seated or standing worker) in accordance with Chapters 5, 6 and 7, Annex A and Annex B to ISO standard 2631-1(1997).

Some people find low-frequency noise and its vibrations very unpleasant.
