A hearing device has a transfer function adjustable by a set of parameters. The hearing device can have two microphones, a processing unit, and a speaker unit. A direction identification unit is operationally connected to the processing unit. Communication between a user of the hearing device and at least one reference person is ensured for changing positions of the user and/or the reference person. The transfer function is adjusted as a function of at least one current reference person direction by changing the set of parameters. The reference person direction encloses an angle with a reference plane of the user.

Method to operate a hearing device and arrangement with a hearing device

Process for modifying an existing breast box for a paper or cartonmaking machine as well as an intermediate portion for carrying out the process. During the fabrication of a breast box for a paper or cartonmaking machine an intermediate portion is interposed between a supply apparatus and a downstream guiding device, with the material suspension flowing through this intermediate portion wherein, via supply lines, located on the intermediate portion, a liquid is added which differs from that of the suspension stream. Particularly, in this manner, already existing breast boxes can be converted, to water dilution technology, with this invention setting forth special embodiments of differing intermediate portions that can be utilized therefor.
