What is claimed is: 1. A method for the manufacture of a sandwich like constructed light weight sheet with sound absorption characteristics, with which an acoustic absorbing cover layer, a substantially grid shaped configured first intermediate layer and a bottom layer are bound with one another, characterized in that, the light weight sheet acquires a defined surface curvature through binding of the individual layers, whereby the implemented cover layer includes a particularly smooth expanded metal, whereby the expanded metal is implemented in the form of at least one metal laminate, whereby the Rayl value of the cover layer is adjustable through the number of the laminates implemented for the cover layer. 2. A method in accordance with claim 1, by which an additional holed intermediate layer is located between the cover layer and the first intermediate layer, and is bound with the cover layer and the first intermediate layer. 3. A method in accordance with claim 1, by which the binding occurs by means of form fitting and/or adhesive bonding. 4. A method in accordance with claim 1, by which metallic material is exclusively used for the individual layers. 5. The method of claim 1 wherein the light weight sheet is mounted to an air inlet for a jet engine. 6. A method in accordance with claim 1, by which intermittent slits are introduced in individual metal strips of the implemented first intermediate layer at intersection points. 7. A method in accordance with claim 6, by which the metal strips of the implemented first intermediate layer are titanium strips. 8. A method in accordance with claim 7, by which the metal strips are cut from a sheet already in their final form. 9. A method in accordance with claim 8, by which the cutting out of the metal strips occurs by means of laser beam cutting. 10. A method in accordance with claim 9, by which the metal strips are more closely inserted into one another. 11. A method in accordance with claim 9, by which the metal strips are provided with holes for weight reduction. 12. A method in accordance with claim 9, by which the metal strips are provided with intermittent wave patterns on both sides. 13. A method in accordance with claim 6, by which the cover layer is a smooth titanium expanded metal. 14. A method for the manufacture of a sandwich-like sheet having sound absorption characteristics, the method comprising: laser cutting individual intersecting metal strips; binding an acoustic absorbing cover layer, a substantially grid-shaped first intermediate layer having the individual intersecting metal strips, and a bottom layer to form the sheet such that the binding causes the sheet to acquire a defined surface curvature; and adjusting a Rayl value of the cover layer by varying a number of laminates employed for the cover layer. 15. A method in accordance with claim 14 wherein the binding an acoustic absorbing cover layer, a substantially grid-shaped first intermediate layer having the individual intersecting metal strips, and a bottom layer to form the sheet such that the binding causes the sheet to acquire a defined surface curvature comprises binding an acoustic absorbing cover layer, a substantially grid-shaped first intermediate layer having the individual intersecting metal strips, a second intermediate layer, and a bottom layer to form the sheet such that the binding causes the sheet to acquire a defined surface curvature, the second intermediate layer being bound to the acoustic absorbing cover layer and the first intermediate layer. 16. A method in accordance with claim 14, by which the binding occurs by means of form fitting. 17. A method in accordance with claim 14, by which the binding occurs by means of adhesive bonding. 18. A method in accordance with claim 14, further comprising: introducing intermittent slits in the individual metal strips of the implemented first intermediate layer at intersection points.
