Ear plugs have actually long Tinnitec  been used by our ancestors. In fact, ear plugs have actually been mentioned in Homer's Odyssey when Odysseus ordered his crew to make shaped ear plugs from melted beeswax to protect them from hearing the sirens' dangerous vocal singing as they cruised past them. This early reference suggests using earplugs in the past; in addition, different materials such as wood, clay-based, cotton, ivory and even silver were used as ear plugs. Imagine making use of an awkward piece of resources merely to reduce the noise! Good thing advancements were made and voila, the very first silicone ear plugs were invented.

Produced by Ray and Cecilia Benner in 1962, the very first silicone variation made a substantial improvement from clay-based and wooden earplugs that it even protected against an usual ear infection referred to as swimmer's ear. In 1972, foam was the following transformative material used for plugs for ears, invented by Ross Gardner. Foam greatly minimized noise, and ironically the motivation came from headphones with foam padding, which had and still do this day, have the capacity to damages ones hearing. Foam is made from Polyvinyl chloride, or polyurethane, or various other acrylic polymer products.

Certainly, aging and genetics make up a big portion of the story of hearing loss. However, there are many other causes that can lead to hearing-related communication challenges. These run the gamut from the proverbial earwax plug to brain tumors. Alarmingly, the numbers of often self-inflicted noise-induced loss of hearing are rapidly rising. As this may be a symptom of an underlying condition, it is important to never simply ignore it, no matter what the age of the person and no matter what the family hearing history might be.

Young ears are not "immune" to hearing loss. Aging baby boomers are no longer the only ones inflating the numbers of this issue. In November 2011, Johns Hopkins Medicine reported that by now 1 in 5 Americans, age 12 and over, has a hearing loss significant enough to interfere with daily communication. Age 12! - those are school-aged children. While researchers figure out the reasons behind the rise in younger people's hearing woes, excess noise is the strongest suspect.
