Do these work for a Monster Truck event , small size for a child?

These earplugs are great for some entertainment activities, the earplugs can properly reduce the noise but retain the music. Earplugs are standard adult size and can fit the ears of some older children.

Are these comfortable to sleep on the side?

These ear plugs are relatively small, you will not feel discomfort when wearing these ear plugs for side sleeping. But the noise reduction effect of these earplugs is not as good as foam earplugs, the main function of the earplugs is to use the internal filter to properly filter the noise and retain the music. It is more suitable for concert.

Snr is 23db, but what is the nrr number on the product epa compliance label?

SNR stands for single number rating and is the standard for the EU while NRR stands for noice reduction rating and is the standard for North America. They are essentially the same rating for different regions. Hope this helps!
