Whether involved in industries that utilize heavy machinery or other loud equipment, protecting workers' hearing is a priority. So, to gain a deeper understanding of an essential aspect of noise protection, let's explore the concept of the Noise Reduction Rating (NRR).

Safety hazards in the oil and gas industry are inevitable. It is a high-risk sector that poses various risks to workers due to the environment and labor work, with a recorded 20 employee deaths in the industry in 2021 (JPT, 2022). Beyond that, an estimated 14% of noise-exposed workers in the oil and gas sector have hearing loss (NIOSH, 2019). Inadequate hearing protection in the oil and gas industry leads to accidents and injuries. Workers who cannot hear warning signals or instructions are at a higher risk of being involved in accidents that can be fatal or have a long-lasting impact. Therefore, to mitigate safety hazards, it is necessary to identify threats and take the right steps to prevent them before it is too late. 

Today is World Hearing Day, which is held every year on March 3rd to raise awareness for hearing loss prevention and promote hearing care across the world. Every year, the World Health Organization (WHO) chooses a theme for World Hearing Day and creates data-driven material to advocate for hearing safety. According to WHO, "World Hearing Day 2023 will highlight the importance of integrating ear and hearing care within primary care, as an essential component of universal health coverage" (WHO, 2023).

Mining presents many risks to all involved, from the financial and investment level, down to the frontline worker in the mines. In the public's mind, the risk of a mining shaft cave-in far outweighs the risks to physical health over time. When health risks are discussed, it has commonly only been about diseases such as black lung disease. However, according to the CDC, "One out of every four mine workers has a hearing problem. Even worse, four out of five mine workers have a hearing impairment when they reach mid-60s retirement age" (Centers for Disease Control and Prevention, 2018). Furthermore, 76% of miners are exposed to hazardous noise daily, which is more than any other major industry.

The steel industry is one of the largest global industries in the world, employing over 6 million people worldwide. It is also one of the louder industrial sectors, with the average noise exposure ranging between 85-92 dB(A) from various equipment including compressors, machine grinders, jets, and hammers. The noise generated by hot and cold rolling mills alone can reach up to 110 dB(A).

Industry leaders in every field value the importance of safety for employees and managers. This emphasis on safety is even more important in fields that include extremely high levels of occupational noise exposure, such as mining or oil and gas. However, in these extremely loud environments, traditional methods of hearing protection just don't provide enough noise reduction. That's where double hearing protection (DHP) comes in. 

Loud-noise exposure can have a wide range of detrimental effects in your workplace. These loud noises can have long-term consequences such as speech interference, sleep disturbance, fatigue, and even different levels of hearing loss.

As mentioned in our overview blog of noise-induced hearing loss, sometimes we experience very loud noise which, even for a brief amount of exposure, can temporarily or permanently damage our inner ears causing noise-induced hearing loss (NIHL). There are often misconceptions about NIHL, but we will debunk these myths. 

When working in an industrial environment, there is no such thing as being gentle with your hearing protection headset. They get dirty, dusty, grimy, and banged up for 8-12 hours or more a day. The ear cushions may get cracked, warped, or just plain dirty. Whatever the reason, these headsets often get replaced due to damage or lack of upkeep. So, how can you extend the life of your hearing protection headset?

When working in hazardous or high-noise-level conditions, it is important to have the right hearing protection. In many cases, this indicates wearing a headset or earmuff hearing protection device (HPD) with active noise-canceling technology. This analog technology functions by detecting the sound coming into the headset generates signals that are out-of-phase with the offending signals and then cancels them out. This allows any sounds generated within the headset to be understood more clearly (music, radio communications, etc.). Unfortunately, these active noise-canceling headsets have attributes that are problematic.
