Abstract
A hearing protection system comprises a hearing protection device adapted for placement over or insertion into a user's ear. The hearing protection device comprises a first microphone arranged to determine an internal sound level characteristic within the user's ear canal. The hearing protection system further comprises a second microphone arranged to determine an ambient sound level characteristic. The system is arranged to compare the internal and ambient sound level characteristics to determine a difference metric therebetween and to generate an indication if the difference metric is greater than a difference threshold and the internal sound level characteristic is lower than an internal sound threshold.
