why does putting wireless earbuds in make some sounds seem louder?

190 views

I’m currently on a train filled with rowdy football lads being rowdy, so I put my wireless earbuds in on the hope that would block out some of the noise. But the voices around me only got louder. Is there a scientific explanation for this? I figured it was something to do with how soundwaves travel through plastic but I don’t know much about acoustics.

If these are basic earbuds with no option for letting in ambient noise (many high end earbuds have such an option) then you might not be making a good vacuum with the silicon tips.

Is it “in ear” one where the silicon tips are inserted inside the ear canal and forms a nice vacuum? If yes then you should test the different sizes of silicon tips and choose one which forms a good vacuum inside the ears.

If these are like the first gen Apple airpods which just hang inside the ear canal with no silicon tip then you are out of luck, such earbuds are useless in blocking outside noise.
