Latest Patents
One of Jean-Marc Lina's latest patents is a method and device for continuous in-ear hearing health monitoring on a human being. This device is designed to continuously monitor otoacoustic emissions (OAE) levels in individual workers. It utilizes a pair of earpieces, each equipped with an external microphone, an internal microphone, and miniature receivers. The device employs adaptive filtering noise rejection processing of the measured distortion product OAE (DPOAE) to enhance the Signal-to-Noise ratio in frequencies where passive isolation is inadequate. The technique relies on a Normalized Least-Mean-Square (NLMS) algorithm, which utilizes the ipsilateral external microphone and the contralateral internal microphone to filter out noise from the measured DPOAE signals. This innovative approach allows for increased reliability in results across a broader dynamic range of DPOAE magnitudes compared to existing methods. The device is particularly suitable for monitoring workers' hearing capabilities in industrial noise environments up to 75 dB(A).
