If a speaker is moved from 2 feet away to 4 feet away, the volume of the sound will: half double quarter stay the same

the volume of the sound will quarter

Explanation:

As you move far away from the source, the loudness of sound decreases. This is because as the distance from the source increases, the area it covers also increases thereby spreading the energy over a great area leading to lesser loudness and intensity.

As a result of this, sound intensity follows an inverse square law:

I ∝ 1/d²; where I is the intensity and d is the distance from source.

Therefore If a speaker is moved from 2 feet away to 4 feet away (increment of 2 feet), the volume of the sound would quarter (1/2² = 1/4)
