Environmental noise or sound pollution continues to be a menace in a big way and poses a considerable threat to humans as well as animal lives today. Machines and vehicles(cars, buses, motorbikes, etc.) mostly add to outdoor noise pollution. The maximum permissible noise levels of 50 decibels are meant for residential areas. Higher noise levels can aggravate cardiovascular problems for people exposed to such high decibel levels. Exposure to high levels of noise at the workplace can lead to hearing loss. Therefore, it is vital to put proper safeguards in place to avoid the harmful effects of higher noise levels. Work-related hearing loss is rampant across the globe, and businesses and organizations have acknowledged the imminent danger extreme decibel levels pose.
Earplugs are inserted in the ear canal to protect the wearer from loud, shrill noises, and intrusion of water and foreign particles in the ear. They reduce the volume of sound and are used mostly to avoid hearing loss and ringing in the ears, also known as tinnitus.
Generally for hearing protection, four types of earplug fittings are used :
a) Foam earplugs - Material composition of foam earplugs includes polyvinyl chloride (PVC) or polyurethane. Memory foam is compressed so that it can be expanded while plugging into the ear canal.
b) Wax earplugs - These earplugs are fitted over the external front of the ear canal in the form of molds.
c) Universal-fit, flanged silicon ear plugs.
d) Reusable ear plugs
e) Uncorded ear plugs
