AI Technical Summary

Technical Problem

Users cannot accurately detect sound leakage when headphones are being worn, relying on subjective feelings to judge whether there is sound leakage, leading to inaccurate detection.

Method used

Audio signals from inside the ear canal and outside the earphone are collected by a feedback microphone and a feedforward microphone, respectively. The energy information of the internal detection signal and the cross-correlation information between the external detection signal and the detected audio are calculated. By combining the reference energy and the cross-correlation information, the sound leakage status of the earphone is determined.

Benefits of technology

It achieves accurate detection of headphone sound leakage, reduces reliance on additional hardware, and saves hardware costs.
