A method and a device for the continuous, mobile non-invasive and aesthetically unobtrusive measurement of important vital parameters, in particular body(core)temperature, arterial oxygen saturation, heart rate, respiration rate (by pulse oximetry), blood pressure, ECG, and substance concentrations in blood or tissue. The measuring site and the position of the sensor components is the (proximal) auditory canal, whereby there results an unobtrusive sensor technology suitable for a stable monitoring in everyday life i.e. even unaffected by motion. The sensor system includes a small evaluation unit and electronics for signal processing and e.g. means for wireless transmission to a mobile phone. Thus physiological parameters become available for long term diagnostics, for outpatients, for monitoring during rehabilitation, or for monitoring the health status in everyday life, while doing sports and during training, for an increase of the safety of individuals or of people with dangerous occupations or risky hobbies.

Apparatus and techniques are provided for precise measuring and monitoring of certain vital signs of patients that have been difficult to measure especially in emergency situations. Sensor may be used for detecting contraction and expansion in the vascular bed of the lining tissue of the external auditory canal during a cardiac cycle to obtain a better indication of certain physiological parameters. Such a signal generally may be superimposed with an additional signal that is primarily due to breathing activity of the patient. Based on various scenarios different sensors may be used to determine the signal due to breathing activity and thus the physiological parameter of interest may be derived. The signal corresponding to the physiological parameter of interest, for example, blood pressure may then be used to monitor the vital signs or control other medical equipment.

Provided is a technique for improving frequency characteristics by an acoustics-related method so that a sound is heard with natural frequency characteristics when a sound-isolating earphone is fitted in a human ear. A sound-isolating earphone is provided with two or more electroacoustic transducers, wherein independently generated sound waves are passed through isolated sound leading pipes and are mixed just before an entrance of an external auditory canal, and a sound wave of which is twice the difference between path lengths of the two sound leading pipes is attenuated. This serves to provide an easy-to-hear improved sound quality by suppressing the sound wave at around 6 kHz that is transmitted with characteristically high intensity in a sound-isolating earphone.
