Oae Screening System

The HOMOTH TE-OAE 4000 PC module pioneers new territory in the assessment of measured otoacoustic emissions. Signalstatistic and signaldynamic features are employed to categorize all measured data. Parameter vectors are transmitted to an expert system as the outcome. The stored samples are compared to all parameter vectors by the expert system, which contains over 10,000 evaluated OAE measurements. If the device is connected to a PC, all data and measured curves can be stored on a hard drive. For printouts, a digital printer that operates at an exceptionally high speed, generating minimal noise, and is cost-effective is employed. An artificial neuronal network is the foundation of the analysis module, which is further enhanced by contemporary fuzzy logic. The outcome is transmitted to the personal computer via the USB port and displayed on the monitor. Using the HOMOTH expert system, it is feasible to obtain an objective hearing test result that is comparable to the subjective assessment of an experienced OAE expert. The actual measured data is automatically compared and evaluated within a matter of seconds. Therefore, the unique expertise of numerous OAE experts is accessible to all. The signaldynamic and signalstatistic parameters are assessed by the analysis module, which also eliminates artifacts and isolates the characteristic components of the emissions. The artifacts, TE-OAE, and SOAE are displayed on the screen. Consequently, the HOMOTH expert system also enables the untrained user of the OAE system to achieve a high level of safety in terms of the result statement. The monitor displays all pertinent diagrams, as is the case with a traditional OAE measurement.
