How do you calculate decibels per decade?

Decade means ratio of frequencies=10. And octave means ratio of frequencies=2. So when we say 20 dB/dec that means slope is 20 and 20 dB magnitude changes in 1 decade. Means when frequency becomes 10 times then magnitude changes by 20 dB.

What is 20 dB per decade?

20 dB/decade means that magnitude changes 20 dB whenever the frequency changes tenfold or one decade.

What is a decade in decibels?

Decibels Rolloff

A decade is a 10X increase in frequency, for example from 100 Hz to 1000 Hz. Saying “minus 20 dB per decade” might mean that the output signal at 1000 Hz is only 110 as large in voltage amplitude as the signal at 100 Hz.

How to convert dB decade to dB octave?

How to convert decibel/decade to decibel/octave ? 10dB/decade = approx. 3dB/octave.
