  • Publication number: 20190343453
    Abstract: A method of characterizing a patient's disordered breathing during a sleeping period includes performing a first partial characterization of a time axis of an audio signal in order to learn the most prominent and highly relevant events. Only at a later stage, i.e., after sufficient observation of the highly relevant events, is a full segmentation of the entire time axis actually carried out. Linear prediction is used to create an excitation signal that is employed to provide better segmentation than would be possible using the original audio signal alone. Warped linear prediction or Laguerre linear prediction is employed to create an accurate spectral representation with flexibility in the details provided in different frequency ranges. A resonance probability function is generated to further characterize the signals in order to identify disordered breathing. An output includes a characterization in any of a variety of forms of identified disordered breathing.

  • Patent number: 10080090
    Abstract: The present invention relates to a medical feedback system (100) based on sound analysis in a medical environment. With a sound scene analyzer (SSA, 10) being capable of analyzing and classifying an audio signal so as to obtain a list of one or more sound sources in the medical environment surrounding the patient, and a sound-level analyzer (SLA, 20) being capable of providing an indicator for perceived levels of corresponding sound from the list of sound sources, advanced sound analysis is possible. Finally, a sound classifier (SC, 30) is arranged for classifying said list of one or more sound sources in a medical environment with respect to a degree of avoidability, and generating a corresponding feedback signal (FEED, 50) for appropriate action by medical personal, patients and/or visitors.

  • Publication number: 20170367663
    Abstract: A method for assisting a user in selecting audible alarm settings of a patient monitoring system for monitoring a patient is provided. A synthesis model is generated in response to 1) data indicative of audio features derived from audio recorded in the patient room, and 2) data indicative of vital signs recorded from the patient monitoring system. Sets of audio parameters indicative of respective plurality of audible alarm settings are then processed according to the synthesis model so as to generate respective outputs, e.g. indicative of audibility of the plurality of alarm sounds according to the audible alarm settings synthesized to be played in or outside the patient room. These outputs can then be presented to a user, so as to allow the user to evaluate e.g. alarm audibility and noise level impact of the plurality of audible alarm settings, and e.g. adjust the settings accordingly, such as alarm thresholds etc.

  • Patent number: 9799210
    Abstract: There is provided a method of operating a device to generate a target sound that is audible to a user of the device, the method comprising measuring background noise in an environment in which the device is located; using a perceptual loudness model to predict an audibility of the target sound to the user of the device based on the measured background noise; using the output of the perceptual loudness model to determine a gain value that is to be applied to a source signal used to generate the target sound in order to provide at least a desired level of audibility of the target sound to the user; applying the determined gain value to the source signal to produce a modified source signal; and generating the target sound using the modified source signal.

  • Patent number: 9765516
    Abstract: A room divider (100) for dividing a room into two sub-portions (R1, R2) and for attenuating sound (S1, S2) travelling between the two sub-portions is provided. The room divider comprises hollow cylindrical elements (110) arranged periodically for dividing the room into the two sub-portions. At least some of the hollow cylindrical elements have a cylindrical shell (111) with at least one slit (112) extending in an axial direction (120) of the shell. The shell extends continuously along the perimeter of the corresponding hollow cylindrical element from one side (113) of the at least one slit to another side (114) of the at least one slit. Each of the at least one slit faces in a local elongation direction (130) of the room divider for increasing acoustic symmetry with respect to the two sub-portions. The use of destructive interference and resonance to attenuate sound allows for a less bulky/heavy acoustically absorbing room divider.

  • Patent number: 9659149
    Abstract: The invention relates to a medical monitoring system (100) based on sound analysis in a medical environment. A sound level analyzer (SLA, 10) is capable of providing an indicator for perceived levels of sound from a number of sound events, and a data storage modality (DSM, 20) is receiving and storing said indicator for perceived levels of sound and also corresponding information from an associated patient monitoring system (PMS, 60) handling information indicative of a physical and/or mental condition of a patient under influence by sound. A sound event analyzer (SEA, 30) is further being arranged for performing, within a defined time window, an overall sound analysis (ANA, 50) related to physical and/or mental condition of the patient that may be influenced by sound in order to assist or supervise medical personal with respect to the acoustic environment.

  • Patent number: 9107018
    Abstract: A sound reproduction system for reproducing an audio signal as originating from a first direction relative to a nominal position (211) and orientation of a listener is provided. The system comprises a first sound transducer arrangement (105) arranged to generate sound reaching the nominal position (211) from a first position corresponding to the first direction; and a second sound transducer arrangement (107) arranged to generate sound reaching the nominal position (211) from a second position corresponding to a different direction than the first direction. The arrangements may specifically be loudspeakers positioned at the given positions. A drive circuit (103) generates a first drive signal for the first sound transducer arrangement (105) and a second drive signal for the second sound transducer arrangement (107) from the audio signal. The first position and the second position are located on a sound cone of confusion for the nominal position (211) and the nominal direction.

  • Patent number: 9014382
    Abstract: A controller for a headphone arrangement (101) comprises a drive circuit (203) which generates a signal for an earphone (105) from an audio signal. The drive signal is fed to the earphone (105) causing this to reproduce the audio signal. A first circuit (217) determines a signal level for the audio signal and a second circuit (209) determines an ambient sound level from a microphone signal from a microphone (109). A third circuit (211) determines an attenuated ambient sound level for the user from the microphone signal and an ambient sound attenuation of the earphone (105). A gain controller (205) controls the gain of the audio drive circuit (203) for the audio signal in response to the ambient sound level, the attenuated ambient sound level and the signal level. The dynamic and automated gain control may be used to reduce the risk of hearing damage e.g. by automatically restricting the sound level experienced by the user to the ambient sound level.
