One of the biggest problems that aviators face is the noise near the aircraft when APUs or engines are operating. Any pilot tries to reduce the impact of noise near aircraft using headphones or base ear-pads.
To solve the problem, many of them get headphones with noise reduction or simple earplugs.
Earplugs for flight: specification of use
Modern earplugs are elastic cones made of synthetic materials that cover the ear canal and prevent the noise impact on the organs of hearing. Companies that release earplugs provide additional guidance on how to insert them into the ears to provide background noise reduction.
Earplugs for plane: noise reduction features
The human ear normally responds to noise in the range of 30-33 dB. The engine noise level 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 frequency range, the use of earplugs reduces the noise level from the engine, but does not affect the audibility of the speech: pilots can quite easily hear each other near the working equipment. According to the requirements of the Occupational Safety and Health Administration (OSHA), people who are exposed to the influence of noise levels above 85 dB must use earplugs.
Representatives of other professions can also use earplugs for pilots: musicians, heavy industry workers, swimmers, diving enthusiasts. They effectively protect the ears of an individual from excessive noise, and help athlete to protect ears from the water.
Materials for earplugs
In the aviation online store Crew Shop (Kiev) you can buy equipment for hearing protection, made of various synthetic materials:
- foamed polyurethane;
Passengers who want to relax without unnecessary noise during the flight buy foam earplugs. The price of such products is low. They do not last long, but they are a perfect fit for several flights. The polyurethane earplugs can be made in the form of a cone or herringbone. They will last much longer. They can be washed. Earplugs perfectly retain their shape and suppress noise.
Silicone earplugs for flight are the most durable. Their wear resistance depends on the frequency of their use and the storage quality. 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, when buying earplugs pay attention to the quality of the material. The cost of silicone products may vary, but is considered to be the highest in this group of products.
Hygiene, ergonomics, contraindications
There are different models on sale, but for easy removal of earplugs, they should have small straps 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 that earplugs are manufactured from should not crumble. Synthetic microparticles in the ear canal are unpleasant and may require consulting a doctor.
Earplugs are contraindicated for people with hearing disorder during active treatment. In such cases, it is advisable to consult your doctor about the advisability of using earplugs during the flight.
The sale and delivery of earplugs is carried out throughout Ukraine. You can buy them both for flight and for home use, especially if you live near noisy highways and want to protect yourself from excessive noise.
