Foam Earplugs, mainly made of memory foam, which are compressed and put into the ear canal, where they expand to plug it. Ear plugs are especially useful to people exposed to excessively noisy devices or environments (80 dB or more)

Safety and Health Research recommends using the roll, pull, and hold method when using memory foam earplugs. The process involves the user rolling the earplug into a thin rod, pulling back on the ear, and holding the earplug deep in the canal with the finger To get a complete seal, the user must wait about 20 seconds for the earplug to expand inside the canal.
