Question

which of the following would be the least helpful in reducing outside noises in your house? sound - proofing your doors sound - proofing windows removing trees from your property installing carpet

Explanation:

To determine the least helpful option for reducing outside noises, we analyze each: Sound - proofing doors (blocks sound through door gaps), sound - proofing windows (blocks sound through window openings), and installing carpet (absorbs sound reflections inside). Trees outside can act as a natural sound barrier (absorb or deflect sound). Removing trees eliminates this barrier, so it is least helpful.

Answer:

removing trees from your property
