Problems solved by technology
[0004] These signals and assessments are often not intuitively detectable to the subjects being examined themselves, as well as to untrained observers, and cannot be interpreted without basic medical knowledge
Evaluation of data and signals is often tedious, even for well-trained monitors
Observation of such temporally variable information, especially of multiple simultaneously monitored organic processes in field monitoring, requires sufficient attention and still often fails to detect the full depth of information

Embodiment Construction
[0063] figure 1 A subject 1 is shown coupled to a plurality of detection devices. Subject 1 wears a chest strap 2 that detects the breathing of subject 1 . ECG3 is also coupled to the subject. To record brain activity, EEG 4 is coupled to subject 1's head via multiple signal collectors. The associated devices are devices according to the prior art, which are not shown in the schematic illustration, since their configuration is not critical to the invention. Crucially, the device is coupled to a processing device 5 having interfaces 5a, 5b, 5c for detection devices. A processing device may include a computer system.
[0064] The conversion of signals detected as analog signals can take place in the detection device itself, ie in the EEG, ECG and chest strap, in order to transmit digital signals via the interfaces 5a, 5b, 5c. Alternatively, the analog-to-digital conversion can be performed at the interface of the processing device 5 . A sound transducer 6 in the form of a ...

The invention provides a method for generating acoustic information according to biological activities of human organisms. A first time signal change curve is generated from measurement of electricalactivities of organism brains, and thus a first data stream is generated; and a second data stream is generated from measurement of electrical activities of hearts, and a third data stream is generated from breath measurement. An acoustic signal is generated in real time in an audible frequency spectrum and output by a sound converter, wherein at least one parameter of the acoustic signal is determined in time according to a current data value from the first data stream, a parameter is determined in time according to a current data value from the second data stream, and a parameter is determined in time according to a current data value from the third data stream. Parameter determination is derived from the data values according to calculation rules or stored allocations, wherein the calculation rules or the stored allocations differ in pairs, and thus the change of each data stream in the data streams cause the associated audible change in the acoustic signal.
Description
technical field [0001] The present invention relates to a method and a device for generating sound information based on biological activities of a human organism. Background technique [0002] Conscious awareness of many organic processes occurring simultaneously in the human body is difficult for one's observer and often for the person himself. In medical technology, therefore, there are many detection devices and detection schemes in order to convert biological signals of humans so that they can be observed or evaluated. [0003] For example, EEG (electroencephalography) systems are known for detecting and evaluating the electrical activity of the human brain. For the electrical activity of the human heart, ECG (electrocardiogram) systems or optical monitoring systems are known and can monitor humans and Patient's breathing. In addition, an EDA system (EDA sensor in the inner surface of the hand) for measuring skin resistance is adopted, or a sensor for measuring oxygen...
