An apparatus for sonic coupling between an intake tract or engine compartment and a vehicle interior of a motor vehicle has a housing into which sound enters from the intake tract via a first line, and out of which sound exits into the vehicle interior via a second line. A transmission body is arranged in the housing, the transmission body having a gas-tight separating wall between a sound inlet into the housing and a sound outlet out of the housing. The position of the separating wall is held essentially constant by a positioning device. A transmission wall between the separating wall and the housing provides an acoutis transfer function that is adjustable. The separating wall runs generally perpendicular to the longitudinal axis of sound propagation and the transmission wall runs at an angle α to the longitudinal axis of sound propagation.

Apparatus in accordance with claim 7, wherein said transmission body has an edge joined to or integral with said transmission wall and acts on said housing. 16. Apparatus in accordance with claim 15, wherein said edge of said transmission body is mounted between a tube edge of said internal tube and an expansion of said external tube. 17. Apparatus in accordance with claim 1, wherein the acoustic transfer function is adjustable by adjusting the effective surface area of said transmission wall. 18. Apparatus in accordance with claim 17, wherein stiffness, a modulus of elasticity, at least one damping characteristic, and/or a mass of said transmission wall is/are variable as an adjustable property of the material. 19. Apparatus in accordance with claim 17, wherein said internal tube has a plurality of apertures and wherein the dimension of each aperture, the number of apertures, and/or the placement of said apertures is/are variable for adjusting the acoustic transfer function. 20. Apparatus in accordance with claim 1, wherein said housing comprises a tube, line, or hose, or is comprised of a tube, line, or hose. 21. Apparatus in accordance with claim 1, wherein said housing is arranged in a flow path of uncompressed intake air of the motor vehicle. 22. Apparatus in accordance with claim 1, wherein said housing is arranged in a flow path of compressed intake air of the motor vehicle. 23. Apparatus in accordance with claim 1, wherein the angle α<��30��. 24. Apparatus in accordance with claim 5, wherein the tension spring is a helical spring and/or the foamed part is a foam wedge. 25. Apparatus in accordance with claim 7, wherein said internal tube is stiff or rigid. 26. Apparatus in accordance with claim 8, wherein said internal tube comprises a plurality of apertures. 27. Apparatus in accordance with claim 6, wherein said internal tube includes material comprising aluminum, plastic, or foamed material. 28. Apparatus in accordance with claim 27, wherein the internal tube includes foamed material in the area of said positioning apparatus. 29. Apparatus in accordance with claim 13, wherein said transmission body is formed in the shape of a flower pot. 30. Apparatus in accordance with claim 15, wherein said transmission body is mounted between said housing and said first line. 31. Apparatus in accordance with claim 15, wherein said edge of said transmission body is mounted between a flange molded on said internal tube and a flange of said external tube that is detachably joined thereto. 32. Apparatus in accordance with claim 31, wherein the flange is detachably joined thereto. 33. Apparatus in accordance with claim 1, wherein the acoustic transfer function is adjustable by adjusting at least one property of the material of said transmission wall. 34. Apparatus in accordance with claim 9, wherein the acoustic transfer function is adjustable by adjusting at least one effective surface area of said aperture(s) in said internal tube. 35. Apparatus in accordance with claim 9, wherein the acoustic transfer function is adjustable by adjusting said aperture in said internal tube.
