A decibel (dB) is a unit of measurement used to quantify the intensity or level of sound. It represents the logarithmic ratio between two values, typically power or intensity, and is commonly used in acoustics and telecommunications. The decibel scale is advantageous for expressing a vast range of values, School Management System from the faintest sound perceptible to the human ear to the threshold of pain. Each 10 dB increase corresponds to a tenfold increase in intensity, making it a powerful tool for comparing sound levels. It’s important to note that the decibel scale is relative and does not have an absolute zero, meaning it measures the ratio between two quantities rather than an intrinsic value.
