BERA 4000 (PC-based module) HOMOTH BERA 4000 PC-module is a real time brainstem audiometer. It is developed considering the latest knowledge of the ENT research. By use of most modern processors, a wide range of possibilities is opened. It is a system lasting into the future for a lot of years, because all changes in diagnostic demands can be loaded as an update or upgrade via software into the system. The software contains pre-selected standard programs, to reduce the operation of the system onto a few keymoves. Beside this, it is possible to create storable measuring programs with individual parameter selections. Further more, the EXPERT-MODE allows to create and change settings during measurement sessions and adapt to changing situations or patients condition. 16 curves can be measured per examination and stored into a temporary memory. The evaluation / analysis can be done afterwards at a later time. All curves are presented high resolution at the colour screen of PC. The program is menu controlled and fitted with a online help. blue line
