Due to the smoothing coefficient, the paper one's voice will paper than plastic ones.

Rough walls will absorb voice waves
Smooth walls will reflect the sound➡️well affect!

We think paper cups are better in sound transmission compared to plastic cups

# data[].attributes.body
Paper cup is porous material ,whereas plastic is non-porous.

Thicker material are prone to resonance and have better sound transmission effects.

# data[].attributes.body
Because paper cups are thicker.
