Foam ear plugs are small pieces of soft molded foam that are inserted into the ear canal to block noises. Foam ear plugs may be used simply to block the sounds of snoring, or they may be used at places where hearing damage is a concern, such as a loud concert, noisy workplace, shooting range, or on a motorcycle, just to name a few. It is a good idea to use ear plugs whenever hearing damage is possible, because hearing damage is irreversible.

Ear plugs are marked with a Noise Reduction Rating (NRR). The NRR is a decibel rating that states the amount of additional protection offered by the ear plugs. For instance, ear plugs with an NRR of 29 offer protection by reducing the noise level by 29 decibels.The higher the NRR, the better noise protection offered by the ear plugs. This rating is specified by the Environmental Protection Agency. It may be helpful to search for a chart online that specifies decibel levels at various events in order to choose ear plugs with an appropriate noise reduction rating for your desired application. The highest NRR currently offered by the use of foam ear plugs is 33; this number can be increased further by wearing noise-reducing earmuffs on top of the ear plugs.Foam ear plugs are typically sold in packs with multiple pairs included in the pack, and are quite inexpensive. There are also some higher quality ear plugs sold individually, and there are even custom made ones available. Typically, foam ear plugs are disposable, and should be thrown away after a few uses. They often come in bright colors to make it clear to others that someone is wearing ear plugs. Most are able to fit entirely inside the ear and are not very noticeable.
