The decibel scale is a logarithmic measurement used to quantify the intensity of sound, expressing it in terms of a ratio relative to a reference level. This scale is critical for understanding and predicting noise levels, as it allows for a more manageable way to convey the vast range of sound intensities humans can perceive. The logarithmic nature of the decibel scale means that every increase of 10 dB represents a tenfold increase in sound intensity, making it essential for tasks such as noise mapping and prediction.
congrats on reading the definition of Decibel Scale. now let's actually learn it.
