re: Recommend Ear Plugs

Just look for the ones with the highest NRR (Noise Reduction Rating). Foam plugs take out noise across the widest frequency band.

Howard Leight has always made excellent plugs. I prefer the Howard Leight Max plugs (NRR 33). Get the uncorded ones (you will just have to pull the cord off anyway to sleep).

Moldex makes excellent plugs, as well. Their Softies have an NRR of 33 and are very soft and comfortable.

Just remember...if you have a small ear canal, standard sized foam plugs can be uncomfortable (putting extra pressure on the ear canal). Ear plugs do come in different sizes.
