Questions You May Have About Ear Plugs

Although soft foam ear plugs seem quite simple things – there are a number of questions that people have about them. So we would like to answer the more common questions we get asked about Ear Plugs.

Q. What does ‘NRR 33db’ mean?

A. The NRR or Noise Reduction Rating rating on ear protection is
much like the SPF (Sun Protection Factor) on sun tan lotion.
It gives an indication of how much you can expect the noise
level to be reduced when you wear the ear plugs. The higher
the NRR rating the more noise will be blocked out. NRR 33db
is the highest level available, and means that the noise
level will be reduced by approximately 33 decibels. So if
you are going to a concert where the noise level will be
110db, when you use Sound Blocker Ear Plugs this level should
be reduced to approximately 77db

Q. Can you get ear plugs to block out 100% of noise?

A. Not at the moment. The highest NRR (noise reduction rating)
currently available is NRR 33db – which is the NRR of the Sound
Blocker Ear Plugs you purchased.
And it’s unlikely that you will ever get ear plugs that will
block out 100% of sound, as the body itself actually absorbs
sound so unless you shut yourself away in a totally sound proofed
room it’s not possible to block out noise completely.

Q. How can I stop my ear plugs falling out?

A. It is very important to insert earplugs correctly, not only
to ensure they do not fall out but also to ensure you get their full
noise reduction capabilities. It does actually take a bit of practice!
