2. The noise-emitting industrial plant as claimed in claim 1 , wherein the working platform ( 14 , 14 ′) is of an outwardly foldable design.
3. The noise-emitting industrial plant as claimed in claim 1 , wherein the noise attenuation hood ( 12 ) has an essentially vertical wall ( 12 a ), and the working platform ( 14 , 14 ′) is a foldout wall segment of the wall ( 12 a ).
4. The noise-emitting industrial plant as claimed in claim 3 , wherein the working platform or the wall segment ( 14 , 14 ′) is connected to the noise attenuation hood ( 12 ) in a foldout manner by at least one swivel joint ( 15 ).
5. The noise-emitting industrial plant as claimed in claim 4 , wherein the rotational axis which is defined by the at least one swivel joint ( 15 ) coincides essentially with the lower transverse edge of the wall segment or of the working platform ( 14 , 14 ′).
6. The noise-emitting industrial plant as claimed in claim 4 , wherein the rotational axis which is defined by the swivel joints extends above the lower transverse edge of the wall segment or of the working platform ( 14 , 14 ′) in such a way that the folded out working platform ( 14 , 14 ′), by a part of its surface, reaches into an interior of the noise attenuation hood ( 12 ).
7. The noise-emitting industrial plant as claimed in claim 1 , wherein the folded out working platform ( 14 , 14 ′) has a predetermined clearance (D) from the ground ( 31 ), and in that supports ( 16 , 16 a , 16 b ) are provided between working platform ( 14 , 14 ′) and ground ( 31 ) for increasing the mechanical stability in an outside regions of the working platform ( 14 , 14 ′).
8. The noise-emitting industrial plant as claimed in claim 7 , wherein the supports ( 16 , 16 a , 16 b ) are releasably connected to the working platform ( 14 , 14 ′).
9. The noise-emitting industrial plant as claimed in claim 7 , wherein the supports ( 16 , 16 a , 16 b ) are fastened on the working platform ( 14 , 14 ′) in a foldout manner.
10. The noise-emitting industrial plant as claimed in claim 9 , wherein the supports ( 16 , 16 a , 16 b ) are integrated into the working platform ( 14 , 14 ′).
11. The noise-emitting industrial plant as claimed in claim 1 , wherein the working platform ( 14 , 14 ′) further comprises a guard rail ( 21 ).
12. The noise-emitting industrial plant as claimed in claim 11 , wherein the guard rail ( 21 ) is fastened on the working platform ( 14 , 14 ′) in a foldout manner.
13. The noise-emitting industrial plant as claimed in claim 12 , wherein the guard rail ( 21 ) is integrated into the working platform ( 14 , 14 ′).
14. The noise-emitting industrial plant as claimed in claim 3 , wherein at least one of sound insulation or pressure sealing ( 17 - 19 ) are provided between the wall segment or the working platform ( 14 , 14 ′) and a part of the wall ( 12 a ) enclosing it.
15. The noise-emitting industrial plant as claimed in claim 4 , wherein the at least one swivel joint ( 15 ) is configured as a hinge ( 15 a ) or as a double hinge ( 15 b ).
16. The noise-emitting industrial plant as claimed in claim 1 , wherein the plant is a gas turbine or steam turbine ( 11 ) plant.
17. A noise-emitting industrial plant ( 10 ), which is enclosed by a personnel-accessible noise attenuation hood ( 12 ) for damping noise which issues from the plant, the noise attenuation hood ( 12 ) comprising a working platform ( 14 , 14 ′) which is provided for at least one of maintenance operations or repair work on the noise-emitting industrial plant ( 10 ), the working platform ( 14 , 14 ′) is arranged as a part of the noise attenuation hood ( 12 ) in a foldout manner and when the working platform is folded out from the noise attenuation hood ( 12 ) it is situated at a predetermined clearance (D) from the ground ( 31 ).
