Hello,
I wondered if anyone already bought those plugs:

I asked noise protection earplugs to the pharmacist and she gave me those. After buying them I had a look at the box and saw it was apparently for sleeping. Does anyone know if they are safe to use in a noisy environment? I checked online and they are rated with a noise reduction of 28dB, so I assume it should be fine but I still have a doubt.
I have a funeral to attend tomorrow and would like to make sure I have good earplugs. The last funeral I went to I used my custom molded silicon earplugs but I did not feel it protected me efficiently from the organ's noise.
