I'm always reading about how low-frequency sounds, "C waves", are different and aren't blocked as well by earplugs or earmuffs. What exactly does this mean, and how does this work? I'm planning on visiting Europe this summer, which obviously means flying overseas.
What kind of earmuffs are especially good for these low frequencies? And what exactly are these C waves anyway?
Thanks.
