A system and method for leak correction and normalization of in-ear pressure measurement for hemodynamic monitoring are disclosed. The system includes an acoustical assembly and a data analysis system. The acoustical assembly includes an earbud system that forms an earbud seal with an ear canal of an individual, where the earbud system includes an earbud with an in-ear acoustic sensor that detects acoustic signals in the ear canal. The acoustic signals include audible signals and infrasonic signals. The data analysis system receives the acoustic signals from the earbud system, identifies hemodynamic pressure signals from a body of the individual included within the infrasonic signals, and identifies signal characteristics of the pressure signals over time. The data analysis system can then correct the hemodynamic pressure signals for effects caused by leaks in the earbud seal based upon changes to the signal characteristics over time.

System and method for leak correction and normalization of in-ear pressure measurement for hemodynamic monitoring

An earbud for detecting biosignals from and presenting audio signals at an inner ear canal and method therefor are disclosed. The earbud includes a nozzle and a housing including a body. The nozzle extends from the housing body and has a proximal end arranged for positioning within an inner ear canal of an individual. An earbud tip of the earbud attaches to the proximal end of the nozzle and is adapted to engage the inner ear canal. The earbud includes a speaker and various sensors including an infrasonic/vibration sensor. The infrasonic/vibration sensor detects the biosignals including infrasonic signals from the body of the individual in the canal, and the speaker transmits sound from an audio source into the canal via the nozzle. The earbud preferably seals the inner ear canal to block external sound while also decreasing an acoustic volume of the canal that amplifies the biosignals prior to detection.
