Frequently Asked Questions
Double hearing protection is generally required when the noise level exceeds 100 dB. In Alberta, occupational health and safety regulations will specify when double protection is necessary. It’s often recommended in industries where extremely loud machinery or activities can create dangerously high noise levels. Using both earplugs and earmuffs simultaneously can provide a higher level of noise reduction by adding the attenuation from both devices together, thereby offering better protection than either method alone.
Double hearing protection, which involves using both earplugs and earmuffs simultaneously, significantly reduces noise exposure in high-decibel environments. This combined approach enhances overall protection by addressing gaps that single protection methods might miss, ensuring better attenuation of harmful sound levels. By layering these protective measures, individuals can achieve a higher level of noise reduction, safeguarding their hearing health more effectively, especially in extremely loud settings such as industrial worksites or during the use of heavy machinery.
