Katie and her mom had an argument. Katie was at the mall when her mom called on her cell phone. What type of noise came up in their communication?

Noise pollution.

Explanation:

Noise pollution is too loud noise that is harmful to health or that significantly reduces the comfort of the environment or significantly impairs work. Noise pollution arises, for example, from traffic and work machines, as well as from noisy events such as open-air concerts. Noise pollution can also arise from industrial plants (such as wind turbines, rock crushers), work machines (such as cargo handling equipment in ports and other sites), individual machines and equipment (such as leaf blowers, clearing and chainsaws, air conditioners), water pumps) and other noise sources. The noise of the work machines also causes inconvenience to the user of the device if the source of the noise is close to the hearing system of the machine operator.
