this is simply not the case in any ear protection that I have
seen for sale in the United States. OSHA regulates the
manufacture specs of most (if not all) ear protection sold in
the United States and the specs specifically state that the
upper frequencies are dampened the most, lowest frequencies
next, and the middle (*speech*) the least. Even the ear
protection (*muffs*) that the people that direct plane traffic
on flight decks and airport tarmacs are attenuated to allow the
frequencies (middle) of speech to be the most prominent.
It's unfortunate they have not helped in your case.
