I did the same thing and, to my befuddlement, found that it did not suffice (even with "33 db" earplugs). A few moments' reflection gave men the answer: both earplugs and firing range headphones are designed to block noise from frequencies _outside_ the range of the human voice and to _allow_ the human voice to come piercing through. This is done for safety concerns as well as for enabling communication in noisy environments.
I now seek earplugs/earphones designed to specifically block the human voice.
- ScottBurson 15y agoThe isolation/frequency curve is one factor, certainly, but a bigger problem is that the ear's response is logarithmic. Even if the earplugs or earmuffs have a perfectly flat isolation/frequency curve, so that all frequencies are attenuated by 33 dB, you can still hear just fine; it's just not as loud. Only if you introduce some masking sound (even white or pink noise will do) in combination with the attenuation can you render the outside sounds inaudible.
- vl 15y agoInterestingly, with well-isolating earplugs, you own breathing and blood movement becomes white noise that helps to mask outside sound even more.
- virmundi 15y agoI noticed the same thing, especially when I just had the firing range headphones. However whenever paired, or even alone did help some. It turned the noise around me into more of Peanut's teacher sound (wawawaan). Earbuds and white noise does seem to help. I've found that binaural beats help block the noise and increase my focus.
