The wood turns into ash and smoke so mass is nor destroyed or created.
Sound travels in waves and the height of the wave is the loudness of the sound.
To decrease sound, you need to make the waves not so high, so you can
- decrease the amplitude
- decrease the height of the crest (lower the top of the wave down)
- increase the height of the trough (bring the bottom of the wave up)
It's all about getting the wave to be closer to the center, to not be so high and low, but to be flatter.

<span>As the Sun sets, the moon rises with the tide that faces the
Earth fully exposed to sunlight. The moon has phases because of its orbit to
Earth which causes the portion we see illuminated to change. The new moon
occurs when the moon is positioned
between the earth and the sun. at full moon and third quarter or called
as the half moon, it happens when the moon is at a 90 degree angle with respect
to the earth and the sun. crescent refers to the moon that is less than half
illuminated by the sun. gibbous refers to more than half illuminated by the
sun. waxing means growing or expanding in illumination and waning means
shrinking or decreasing in illumination.</span>
