The ear canal (external auditory meatus, external acoustic meatus), is a tube running from the outer ear to the middle ear. ...
Protection from water Some earplugs are primarily designed to keep water out of the ear canal, especially during swimming. These may be made of wax or silicone which is custom-fitted to the ear canal by the wearer. candle wax This page is about the substance. ...

An effective and simple ear plug to block water from the ear canal is a cotton ball saturated with petroleum jelly. (Gently knead an equal volume of cotton ball and jelly together. Cut into bean sized plugs.)A 2003 study published in Clinical Otolaryngology, found that the cotton ball/petroleum jelly ear plug was more effective at keeping water out of the ear, easier to use, and more comfortable than wax plugs, foam plugs, EarGuard, Aquafit, or EarSeal. The cotton ball/petroleum jelly plugs are not intended as hearing protection.

 Disposable foam earplugs: with coins for scale (top) and inserted into the wearer's ear. Current earplug material was discovered in 1967, at National Research in the USA, by Ross Gardner and his team. As part of of a project on sealing joints, they developed a resin with energy absorption properties. This E-A-R material was later developed into commercial memory foam earplugs.

How memory foam reacts to heat Memory foam is made from polyurethane with additional chemicals that add to its viscosity level, thereby increasing its density. ...
This kind of earplug protection is often worn by industrial workers who work within hearing distance of loud machinery for long periods of time. Earplugs are rated with "Noise Reduction Ratings" or NRRs (Single Number Ratings, or SNR, in the European Union), which provide a guide to the noise protection, in decibels, afforded by the device. Ratings usually spead between 26 to 33 decibels. Traditionally, workplace noise has been a hazard linked to heavy industries such as ship-building and associated only with noise induced hearing loss (NIHL). ...
The decibel (dB) is a dimensionless unit of ratio which is used to express the relationship between a variable quantity and a known reference quantity. ...
Most earplugs are made of memory foam that is typically rolled into a tightly compressed cylinder (without creases) by the wearer's fingers and then inserted in the ear canal. Once released, the earplug expands until it seals the canal, blocking the sound vibrations that reach the eardrum. Other plugs simply push into the ear canal without being rolled first. Sometimes earplugs are connected with a cord to keep them together when not in use. Other common material bases for earplugs are wax or silicone, which is rolled into a ball and carefully molded to fit over the external portion of the ear canal, providing a snug custom fit for the wearer.

Other devices that provide hearing protection include electronic devices worn around and/or in the ear, designed to cancel out the loud noise of a gunshot, while possibly amplifying quieter sounds to normal levels. While rich in features, these electronic devices carry a price over one hundred times their foam counterparts.
Since they reduce the sound volume, earplugs are often used to help prevent hearing loss and tinnitus (ringing of the ears), amongst other ailments. Tinnitus (IPA pronunciation: or ,[1] from the Latin word for ringing[2]) is the perception of sound in the human ear in the absence of corresponding external sound(s). ...
Musicians' or 'Hi-Fi' earplugs Some earplugs are manufactured to provide a direct decibel drop without affecting the user's perception of bass and treble levels. These are commonly used by musicians and technicians both in the studio and in concert to avoid overexposure to high volume levels whilst providing a good balance over the frequency range. The decibel (dB) is a dimensionless unit of ratio which is used to express the relationship between a variable quantity and a known reference quantity. ...

 Musicians' earplugs. The Grey end caps contain an acoustic transmission line with a damper (attenuator) at the end while the domed flanges form a seal in outer part of the ear canal. The output port can just be seen as a small hole at the near end of the left plug Musicians who perform music styles noted for their loud nature, especially rock music, often wear earplugs to prevent their own performances from deafening them.

Musicians' earplugs are designed to attenuate sounds evenly across the audio band thus enabling musicians to still hear upper harmonics, vocals, cymbals and other high frequencies etc clearly, but at a reduced volume level. This type of earplug usually gives an attenation of only about 20dB and are not intended for protection from very high noise levels (>105 dB). Earplugs for musicians are made by a number of firms. Attenuation is the decrease of the amount, force, magnitude, or value of something. ...
An audio frequency (abbreviation: AF) is any frequency from about 20 hertz to about 20 kilohertz, which is the approximate range of sound frequencies that is audible to humans. ...

Flight ear protection Earplugs are available which help to protect ears from the pain caused by airplane cabin pressure changes. Products like EarPlanes contain filters which equalize the air pressure between the inner and outer ear thereby preventing pain during landings and take-offs. The effectiveness of the relatively expensive pressure equalizing earplugs is questionable in performing any better than regular types. They also do not seem to have any effect in decreasing barotrauma. Barotrauma is physical damage to body tissues caused by a difference in pressure between an air space inside or beside the body and the surrounding gas or liquid. ...
