Question

what do decibels, symbolized as db, measure?
wind speed
light intensity
temperature
noise intensity

Explanation:

The image shows a chart titled "NOISE LEVELS" with various noise sources and their corresponding decibel (dB) values. Decibels are a unit used to measure the intensity or loudness of sound, which is directly related to noise intensity. Wind speed is measured in units like miles per hour or meters per second, light intensity in lumens or candelas, and temperature in degrees (e.g., Celsius, Fahrenheit). Since the chart is about noise and uses decibels, it clearly indicates that decibels measure noise intensity.

Answer:

noise intensity
