Claim:
1. A method for producing a microelectromechanical transducer, the method comprising: producing a plurality of microelectromechanical transducers on a single wafer, wherein each transducer comprises a diaphragm; dividing the wafer into a first region and a second region; establishing mechanical tensions of a random sample of diaphragms of the first region; comparing values of the established mechanical tensions of the random sample of diaphragms of the first region with a predetermined desired value; establishing mechanical tensions of a random sample of diaphragms of the second region; comparing values of the established mechanical tensions of the random sample of diaphragms of the second region with the predetermined desired value; adjusting the mechanical tensions of the diaphragms in the first region to the predetermined desired value; and adjusting the mechanical tensions of the diaphragms in the second region to the predetermined desired value.
