Because sounds are made up of waves of compressed and decompressed air, and when two waves meet that are exactly out of phase, or opposite each other, then the total sound produced is zero. See "sound cancellation" in the link below.

When sounds overlap?

When sounds overlap, they can create interference patterns known as interference or inharmonicity. This can result in a phenomenon called constructive interference, where the sounds reinforce each other, or destructive interference, where the sounds cancel each other out. The interference can change the overall quality and perceived loudness of the sounds.


What effect causes sounds from two sources to cancel each other out?

When two sounds are exactly out of phase and have the same amplitude, they undergo destructive interference, causing them to cancel each other out. This occurs when the peaks of one sound wave align with the troughs of the other, resulting in a reduction or complete elimination of sound.

Does calories and treadmill cancel each other?

no, calories and a treadmill do not cancel each other. Calories are burned by excercising. If you eat more calories than you burn, you will most likely lose weight.
