dB to Hz Converter

This tool converts deciBel Hertz (dB-Hz) to Hertz (Hz).

🔄 Hz to dB

Background

deciBel or dB represents a ratio of two numbers – typically Amplitude or Power Levels. The units are the same and hence dB is simply a ratio.

Hz is a unit of frequency and is equivalent to cycles per second.

dB-Hz or dB (Hz) is the bandwidth relative to 1 Hz

A linear number can be converted to its dB equivalent using this calculator. the formula is Plinear = 10(PdB/10)

Similarly,

Hz = 10(dB-Hz)/10

dB has a logarithmic nature. The beLinearnefit of using dB is that a very large (or very small) ratio can be conveniently represented by a small number. For example, 10000000000 Hz = 100 dB-Hz.

Example Calculations

20 dB-Hz is equivalent to 100 Hz.

Similarly 30 dB-Hz is equivalent to 1000 Hz.
