Earplugs are placed in the ear canal to block out extreme sound or to avoid water, filth or foreign physical bodies from entering the ear. However where do they originate from?
A brief History of ear plugs
Ear plugs have actually long been utilized by our ancestors. In fact, ear plugs have actually been referenced in Homer's Odyssey when Odysseus ordered his crew to make molded ear plugs from melted beeswax to protect them from hearing the sirens' deadly vocal singing as they sailed past them. This early reference suggests using earplugs in the past; additionally, numerous materials such as timber, clay-based, cotton, ivory and even silver were utilized as ear plugs. Imagine using an uneasy item of basic material just to decrease the sound! It was a good thing that improvements were made and voila, the very first silicone ear plugs were developed.
Produced by Ray and Cecilia Benner in 1962, the very first silicone variation made a huge renovation from clay-based and wooden earplugs that it even stopped a typical ear infection referred to as swimmer's ear. In 1972, foam was the next evolutionary material utilized for plugs for ears, developed by Ross Gardner. Foam substantially reduced sound, and ironically the inspiration came from headsets with foam padding, which had and still do this day, have the potential to damage ones hearing. Foam is made from Polyvinyl chloride, or polyurethane, or various other acrylic polymer materials.
Foam ear plugs are the most extensively utilized. They are easy to roll, compress, and mold to fit inside the ear canal. When decompressing the foam seals the ear canal so well that it substantially decreases sound within a provided environment This makes foam versions suitable for usage when sleeping, learning, reading, in work environments bordered by noisy equipment and even landscaping.
So the next time you feel like your ears need a break from the stress and sound around you in the house, while taking a trip, think about the history behind your hearing protection and enjoy the silence.
