    Explained below

    Explanation:

    Beats are interference pattern between two sounds of slightly different frequencies perceived as periodic vibration in volume whose rate is difference of the two.

    Both octave and decibel are the terms of measurement.

    Octave (In electronics) is a logarithmic unit for ratio between frequencies, with one octave corresponding to doubling of frequency. For example frequency one octave is from 40 Hz to 80 Hz.

    Whereas decibel is a unit of sound intensity. It is one-tenth of A bel. In electronics it is used measure power level of an electrical signal by comparing it with given level of logarithmic scale.
