An estimated 275 million people across the globe can’t hear clearly all the sounds they love. These people suffer from hearing loss, which the World Health Organization lists as the number one sensory disability in the world.
The most common cause is excessive noise. Whether it’s a one-time exposure to an intense, “impulse” sound, such as gunfire, or by repeated exposure to loud sounds over time, such as machinery at work, noise has the potential to rob people of their hearing.
