Cities often plant thick rows of trees along busy roadsides in a project known as the 'Green Muffler'. How do trees help reduce noise pollution?
  1. Trees absorb and scatter sound waves, reducing their intensity
  2. Trees cool the air so sound cannot travel through it
  3. Trees produce opposing sound waves that cancel traffic noise
  4. Trees slow down moving vehicles automatically

Solution

Dense vegetation acts as a natural sound barrier by absorbing and scattering sound vibrations.
