How does the number of speakers affect the amount of noise in a room What is the dependent and the independent variable?

The number of speakers in a room generally increases the overall noise level, as more voices contribute to the sound intensity. As the number of speakers rises, the cumulative sound they produce can lead to higher decibel levels and increased auditory clutter. In this scenario, the independent variable is the number of speakers, while the dependent variable is the amount of noise measured in the room.
