Hertz (Hz) means the unit of cycles per second (1/T). It has to do with the frequency. Decibel (dB) is a logarithmic unit of measurement that expresses the magnitude of a physical quantity.
Since it is a ratio of two quantities with the same unit, it is a dimensionless unit. Both have nothing to do with each other. It is totally different, like cars and bananas.
The bell is a large unit, so a subunit, a decibel, is usually used. There is no subunit of decibel.

Hz is a measure of frequency. Decibel is a measure of loudness/volume/amplitude. The two can not be equated.

Frequency has a 'Q' in it.
dB HL stands for decibel Hearing Level, and dB SPL stands for decibel Sound Pressure Level.
What is the Diffeence between the In band and Out of Band Frequency Diversity
differenve between frequency management and channel assignement
The difference between frequency modulation and phase modulation is that with frequency modulation the angular frequency of the signal is modified while with the phase modulation, the phase angle of the signal is modified.
Time period = 1 / frequency. Frequency = 1 / time period.
Time period = 1 / frequency. Frequency = 1 / time period.
Sound has three characteristics : 1) Loudness : Measured in decibel. 2) Pitch : It is directly proportional to the frequency of sound. 3) Quality (or Timbre) : It is the difference in the quality of sound.
