| Definition | The logarithm to the base 10 of the ratio of the mean-square or root-mean-square of the sound pressure of underwater ambient noise measured within the specified frequency band and the specified time interval relative to a reference pressure value of 1 micropascal (squared if using the mean-square pressure). | ||
