AI Technical Summary

Technical Problem

Conventional hearing aids rely on static amplification based on ISO standard hearing threshold tests, which fail to account for non-linear hearing loss behavior at high sound pressure levels, leading to under-amplification or over-amplification and inefficient use of the dynamic range, resulting in inadequate hearing restoration and potential further hearing damage.

Method used

A dynamic hearing recovery device that uses data from equal-loudness hearing tests to create a gain table for dynamic amplification, adjusting amplification based on sound pressure levels, and employing gain sail optimization to prevent excessive gain and acoustic feedback, while utilizing filters with matched bandwidths to maintain sound quality.

Benefits of technology

The device effectively compensates for non-linear hearing loss, optimizes the dynamic range, reduces the risk of further hearing damage, and maintains sound quality by dynamically adjusting amplification, ensuring clear and safe auditory experience.

Abstract

[Solution] The present invention discloses a dynamic hearing recovery device comprising a software unit for offline and / or online processing for compensating data obtained from auditory evaluation and / or correction tests, the software unit for offline and / or online processing is configured to process and compensate acquired data collected from a subject by identifying and selecting candidate correction frequencies to which a correction gain can be applied, by performing a method which includes the steps of acquiring data from a subject and, in the acquired data, searching for peak frequencies in which the required correction gain is higher than adjacent frequencies, and then, preferably, calculating the weight of all identified peaks based on the distance to adjacent peaks and the correction gain of each identified peak, wherein the weight of all identified peaks is then the product of the distance to the peak and the correction gain of the peak.
