Thaniks, Ralph and Oren. You've convinced me that there are times I'm
not in an MRI when I should reallly try the headphone type. They came
with the house, and coming from NY, I was alreaday used to the foam,
which they even sell in the NYC subway stations. (though the new trains
starting 35 years ago are much quieter.)

The foam EAR brand is good, but they need to be changed often. There are
other brands that are made of harder plastic that last longer. You hve to
look at the DB reduction ratings to see which ones knock the noise down the
best. The higher the DB rating means less noise going to your ear, but they
must be put in your ear correctly. The foam type usually expand to the
ear,but the harder type sometimes come in differant sizes.

If this is just a one time thing and you have to bring your own, go with the
foam type ear plugs if the headphone type has metel in it and you can not
use them in the MRI machine.

I always wear the headphone types when mowing the yard and using other small
engine yard tools like the weedeater and chain saw.
