Occupational hearing loss is a serious problem & concern for those working in various industries across the globe. As technology has progressed, more and more people have moved into high-noise occupations, surrounded by loud activity and machinery that could damage unprotected ears over time.

Losing the ability to hear can be a significant deftriment to one’s life, and in most cases the damage is irreversible. Hearing is a vital sense that provides you the situational awareness to communicate proficiently, detect dangers, and live comfortably. Without these advantages, a person’s daily experience is severely limited. Being unable to have proper conversations with others or hear surrounding noises often leads one to become isolated, which can result in depression.

The Centers for Disease Control (CDC) has declared noise-induced hearing loss as the most common workplace injury in the United States, estimates that over 22 million workers are exposed to hazardous sound levels annually. Noise is considered harmful to the human ear when it reaches over 85 decibels (dB), comparable to a person raising their voice to you from an arm’s length away.

How do I know whether I'm at risk of hearing loss?

Today, humans work side-by-side with innovative machines to greatly enhance our communication, production, transportation, and military capabilities. These technologies benefit every industrial sector of the economy, but they tend to be quite noisy and often pose a risk to the human ear. The Centers for Disease Control (CDC) has declared that noise-induced hearing loss is the most common workplace injury in the US, affecting over 22 million workers annually. They have determined that noise levels become hazardous when exceeding 85 decibels (dB), and the general rule of thumb is if talking to someone an arm’s length away requires raising your voice, then the surrounding noise may be harmful. The table to the right depicts levels of noise produced by various objects.

Industries posing the highest risk to hearing

Military – Unsurprisingly, operating around gunfire, explosions, and aircraft often inflicts lasting auditory damage on returning veterans. Hearing protection is required in combat situations to protect against hearing loss, as is reliable radio communications to co-ordinate with your unit.

Firefighters – Firefighters are consistently exposed to hazardous noises such as the sirens on firetrucks which are over 120 dB. Moreover, the job requires seamless communication in order to save lives and safeguard against needless injuries. Hearing protection is essential in these situations, and communication capabilities greatly enhance job effectiveness.

Construction – Construction sites are full of loud tools and machinery that operate up to around 110 dB. Since this industry makes up a large portion of the economy, construction workers are one of the highest demographics at risk of hearing loss in the workplace.

Airport Personnel – Working flight operations involves exposure to high levels of noise from aircraft engines, takeoff preparations, & aircraft braking. Jet engines are the largest source of the hazardous sound by far, with levels up to 140 dB. These environments are a constant source of harmful noise, making hearing protection a necessary safety measure.
