TE-OAE 4000

Audiometry

Product description

HOMOTH TE-OAE 4000 PC module treads new paths in evaluating results of measured Otoacoustic Emissions. All measured data is classified according to signalstatistic and signaldynamic features. The result is transmitted to an expert system as parameter vectors. The expert system, containing more than 10.000 evaluated OAE measurements, compares all parameter vectors with the stored samples. All data and measured curves can be stored on harddisc, if the device is connectet to a PC. For printouts, an extremely fast digital-printer, working very noiseless and economical is used. The analysis module consists of an artificial neuronal network, supplemented by modern fuzzy logic. The result is transmitted to the personal computer, via USB port, and is presented on the monitor. Using the HOMOTH expert system an objective result of a hearing test, comparable to subjective evaluation of an experienced OAE expert, is possible. The actual measured data is compared and evaluated automatically within a few seconds. So everybody is able to use the special knowledge of many OAE experts. The analysis module evaluates the signalstatisticand the signaldynamic parameters, the artefacts are eleminated and the characteristic components of the emissions are isolated. The screen shows the SOAE, TE-OAE and the artefacts. Therefore the HOMOTH expert system also allows the untrained user of the OAE system, a very high safety regarding the statement of result. As for a classical OAE measurement, all relevant diagrams are displayed at the monitor. The HOMOTH TE-OAE expert connects all advantages of the classical OAE diagnostic with the most modern computer technology as neuronal networks and fuzzy logic.
