Product Description
Whether you’re going to a concert or a ball game, traveling on a noisy train or plane, doing loud yard work, riding a motorcycle, or just trying to get a better night’s sleep, the EarFirst T23 earplugs offer a reliable, reusable solution. They’re made of thermoplastic elastomers (or TPE), which are nontoxic, tear resistant, and easy to clean Read More
My apologies if that's the case, although by the insults you were dishing out earlier I find it hard to believe you would find the way I addressed your comments offensive. However, I did in no way mean to hurt any feelings and I simply wanted to have a debate over the validity of this product. On that note, what are your thoughts on what I said? Beyond the offensive part of course.
jpkebI was kidding—I’m not not particularly sensitive and you didn’t hurt my feelings. Your comments were quite good and have completely changed my thinking on the subject —and on the meaning of life for me in general. Many thanks!
Every earplug sold in the U.S. is required by law to have a Noise Reduction Rating (NRR) published for it and also the data used for calculating the NRR - the mean Real-Ear Attenuation at Threshold values and the standard deviations of the attenuation values for the one-third octave bands of noise centered at 125, 250 500, 1000, 2000, 3000, 4000, 6000, an 8000 Hz for a group of ten listeners as measured in accordance with ANSI S3.19 Experimenter Fit Procedure. That applies regardless of whether the earplug is intended for the occupational, recreational, or home environment. There is no legal way to have an earplug designed to reduce noise for any application that is free from this requirement. So, where are the data for this earplug?
To be fair, those square cut little cylinder plugs are about as uncomfortable as wadding brown paper towels in your ear. They're also only really meant to be worn for 2-4 hours rather then a full 10 hour shift.
it depends on the genre of music. I am a fan of metal, punk, and industrial acts. All of which tend to the louder side. Rock, jazz, country etc all tend to stick to modest SPLs, and as you move up to higher quality venues, the SPLs actually decrease, because they have better sound systems that dont have to melt your face trying to reach the whole audience.
These are relatively flat up to 1kHz, but above 1kHz, the rolloff is substantial. ~20dB reduction under 1kHz, up to 32dB reduction at 2kHz - 4kHz. These will definitely provide an appreciable level of protection in a situation where you’re not concerned about acute hearing damage (anywhere where most people are not wearing hearing protection), but these cannot compete with higher-end high-fidelity/flat in-ear hearing protection plugs and they are about 50-75x more expensive than foam disposables that will be more effective and only slightly less flat. For $18, you can’t go too wrong, but don’t expect these to keep up with a professional product or blow away expectations compared to a disposable.
MiraColeHuman hearing is subject to the Fletcher-Munson loudness curve. Our hearing is most sensitive in the range from 2khz to 4khz. And falls off rapidly moving toward the lower frequencies. In order for you to hear flat with earplugs. You actually want an earplug with less attenuation of high and low, more attenuation of midrange.
