The trees absorb noise, how? If it absorbs noise which is in form of waves, therefore, can it absorb network waves?

sound is a form of energy, which is produced when an object vibrates. These vibrations are carried in the surrounding, through the air.

The tree acts as a noise barrier and reduces noise pollution through a phenomenon called sound attenuation, which is the damping of sound. Thus effectively decrease the noise. Trees attenuate noise by deflection, refraction, absorption, and masking.

Generally, noise attenuation occurs when sound waves propagate over long distances until there is no energy left to vibrate the air.  A tree barrier in an open distance of 30 metres or 100 feet can reduce sound by 21dB.
