T-OAE
Product catalog summary
System Requirements: The device requires a Pentium PC with a minimum of 800 MHz and is compatible with Windows 98, ME, 2000, and XP. It needs a USB port version 2.0 or a free PCI 2.1-slot with USB Port 2.0.
Standards: The device complies with EN 60601-1/1-1/1-2, MPG, and NUB rules.
Specifications: The stimulus is a clickquartett with a 20 ms rate and intensity of approximately 80dB, featuring automatic gain control. The probe is of miniature design with pressure ventilation and real-time control via FFT. The converter is 12Bit/100kHz, and the amplifier has an 80dB automatic gain setting.
Measurement and Analysis: Measurements are manually adjustable across various clickquartetts. The system includes automatic artefact recognition and elimination. Results are presented in a time window with correlating measurements, spontaneous emissions, and spectra of stimulus and emissions. Parameters for SNR, stability, and reproduction are included, with automatic analysis by an expert system.
Dimensions and Accessories: The device measures 290 x 250 x 75 mm and weighs 1.8 kg. It includes a 2000 mm probe-cable, a miniature probe with ear plugs, an external power pack, a USB communication cable, a program CD, and an instruction manual.
Innovative Features: The HOMOTH T-OAE 4000 introduces a novel approach to evaluating Otoacoustic Emissions using signal statistics and dynamics. An expert system with over 10,000 evaluated OAE measurements compares parameter vectors with stored samples using an artificial neural network and fuzzy logic. This allows for objective hearing test results comparable to those of experienced OAE experts.
Company Information: HOMOTH Medizinelektronik GmbH & Co KG is based in Hamburg, Germany. Contact details include phone and fax numbers, as well as an email address and website.

T-OAE 4000 As a world novelty, HOMOTH 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. 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....
