Earplugs


One of the biggest problems that aviators face is the noise near the aircraft with operating APUs or engines Any pilot is trying to reduce the impact of noise near aircraft using headphones or base earbuds
To solve the problem, many acquire noise-canceling headphones or conventional earplugs For the first time this term was applied by Soviet academician IAT Petryanov-Sokolov, the abbreviation consists of two words "take care of your ears"

Earplugs for flight: features of use


Modern earplugs in the ears are elastic cones made of synthetic materials that cover the ear canal and prevent the influence of noise on the organs of hearing Companies that release earplugs provide additional guidance on how to insert them in the ears to provide background noise reduction

Earplugs for an airplane: noise reduction features


The human ear normally responds to noise in the range of 30-33 dB The noise level of the engines is about 85-40 dB This is noise at low frequencies Earplugs should reduce noise to an acceptable level for hearing Since human speech is in the middle range of frequencies, the use of ear plugs reduces the noise level from the engine, but does not affect the audibility of speech - pilots can perfectly calmly hear each other near operating machinery According to the requirements of the Federal Agency for Occupational Safety and Health (OSHA), people exposed at work to the effect of noise levels above 85 dB, must use earplugs
Earplugs for pilots can be used by representatives of other professions - musicians, workers of heavy industry, swimmers, diving enthusiasts They effectively protect human ears from excessive noise, and the ears of the athlete also from water

Materials for Earplugs


In the online store Crew Shop (Kiev) you can buy equipment for hearing protection, made of various synthetic materials:
  • Foam;
  • polyurethane
  • foamed polyurethane
  • Silicone

Foam rubber earplugs are purchased for passengers who want to relax without unnecessary noise The price of such products is low They will not last long, but they will be perfect for several flights The plugs for ears made of polyurethane can be made in the form of a cone or Christmas tree They will last much longer They can be washed Ear plugs perfectly retain shape and suppress noise
Silicone flight ear plugs are the most durable Their wear resistance depends on the frequency of their use and the quality of storage They can be made of a softer or more rigid silicone, in the form of cones or cylindrical plugs
When buying earplugs, pay attention to elasticity and softness The higher the elasticity, the better the canal is closed and the noise is suppressed Dense silicone can press on the auricle, thereby causing discomfort Therefore, buying earplugs, pay attention to the quality of the material The cost of products made of silicone may vary, but is considered to be the highest in this group of products

Hygiene, ergonomics, contra-indications


On sale there are different models, but for easy removal of ear plugs, they should have small ears on the sides or a connecting cord that will allow them to be easily removed from the ear canals Products should be easy to wash and dry quickly The material from which they are made should not crumble Synthetic microparticles in the ear canal are unpleasant, and can lead to a doctor
Ear plugs are contraindicated for people with ear plugs and earaches during active treatment In such cases, it is advisable to consult with your doctor regarding the advisability of using earplugs during the flight
Sale and delivery of ear plugs is carried out all over Ukraine You can buy them both for flight and for home use, especially if you live near noisy trails and would like to shield yourself from unnecessary noise
