Abstract
The present disclosure provides a hearing protection method capable of blocking external high-sound-pressure-level energy, including: a second sound pressure energy threshold being greater than a first sound pressure energy threshold; when an external sound energy value is greater than the first sound pressure energy threshold and is less than the second sound pressure energy threshold, enabling a preset active noise cancellation function; and when the external sound energy value is greater than the second sound pressure energy threshold, disabling the preset active noise cancellation function, and blocking high-sound-pressure-level energy by means of passive noise cancellation. The present disclosure can block the external high-sound-pressure-level energy.
