What is the decibel scale? Describe how it is defined. What is the decibel scale? A. The decibel scale is a scale that is used to compare the acidity of substances. B. The decibel scale is a scale that is used to compare the magnitude of earthquakes. C. The decibel scale is a scale that is used to compare the loudness of sounds. Done the above.

The decibel scale is a logarithmic scale used to measure the intensity of sound. It quantifies sound levels relative to a reference level, typically the threshold of hearing (0 dB), which is the quietest sound the average human ear can detect. Each 10 dB increase on the scale represents a tenfold increase in sound intensity, meaning that a sound measured at 90 dB is 10 times more intense than one at 80 dB. In everyday life, the decibel scale is crucial for understanding sound environments. For example, a whisper typically measures around 30 dB, normal conversation hovers around 60 dB, and sounds above 85 dB can potentially harm your hearing if you're exposed for prolonged periods. This knowledge helps us make informed choices about noise exposure and the use of hearing protection in loud environments!
