1. A hearing protection method capable of blocking external high-sound-pressure-level energy, comprising the following steps:
Step S1: presetting a first sound pressure energy threshold and a second sound pressure energy threshold, the second sound pressure energy threshold being greater than the first sound pressure energy threshold;
Step S2: obtaining an external sound energy value;
Step S3: comparing the external sound energy value with the first sound pressure energy threshold and the second sound pressure energy threshold, when the external sound energy value is greater than the first sound pressure energy threshold and is less than the second sound pressure energy threshold, performing Step S4, and when the external sound energy value is greater than the second sound pressure energy threshold, performing Step S5;
Step S4: enabling a preset active noise cancellation function to reduce high-sound-pressure-level energy; and
Step S5: disabling the preset active noise cancellation function, and blocking the high-sound-pressure-level energy by means of passive noise cancellation.
