AI Technical Summary

Technical Problem

Existing technologies make it difficult to achieve personalized hearing loss compensation in products that use speakers to play audio signals, and existing methods suffer from poor applicability, noise amplification, and high signal processing resource requirements.

Method used

Audio signals are filtered using a dual second-order filter bank. By generating test signals, determining threshold values, and fitting filter parameters, personalized loudness compensation is achieved, including the application of low-pass IIR and high-pass IIR filtering models.

Benefits of technology

It enables personalized audio enhancement of the audio signal played by the speaker, improves the clarity of sound perception for people with hearing impairments, reduces noise amplification, and lowers signal processing latency and resource requirements.

Abstract

This invention relates to a personalized loudness compensation method, apparatus, computer device, and storage medium. The method includes: acquiring an audio signal to be loudness compensated; determining the parameters of each filtering model in a bisecond-order filter bank, wherein the bisecond-order filter bank includes multiple filtering models; and filtering the audio signal using the bisecond-order filter bank according to the parameters to obtain a loudness-compensated audio signal. This method can provide personalized audio enhancement for hearing-impaired users of mass-market products such as televisions or mobile phones that use speakers to play audio signals.
