This question can't be answered because the two items (Hertz and Decibel) are not related. Hertz is a measure of frequency and Decibel is a measure of power.
1 kilohertz=1000 hertz 30 hertz = .03 kilohertz
This is a mute question because Hertz is a measurement of frequency and Wattage is a measurement of power.
there are 1000000000000Hz in 1 terahertz
Another name for Hertz is cycles per second. So a Megahertz is 1 million cycles per second.

The middle C note on a piano is tuned to 261.63 Hertz (accurate to two decimal places).
Assuming the frequency of Middle C to be 261.63 hertz, accurate to two decimal places, taking this two octaves down brings us to 65.41 hertz. Sending us down a further semitone gives us 65.41 x 1/21/12, which sends us to B, at a frequency of 61.74 hertz, accurate to two decimal places, the closest possible genuine note to a 60 hertz frequency. Effectively, this is the third B below middle C, including that which is a semitone below.
432 Hertz was the frequency of the note A, used as the standard of tuning for musical instruments prior to the shift to 440 Hertz. Many people see a significant link between 432 Hertz and the human mind, suggesting that the frequency subconsciously relaxes our brain. That is why many people are pushing for 432 Hertz as the concert tuning pitch.
According to Wikipedia, the Bb above middle C is roughly about 465 hertz.

Given that the A above middle C has a frequency of 440 hertz, the lowest note on a regular piano has a frequency, rounded to two decimal places, of 27.50 hertz. Taking this an octave further down gives a frequency of 13.75, too low for a human ear to hear. Descending ten semitones, to two Bs below the bottom end of a piano, gives a frequency approximately equal to 13.75/(2^(1/12)10) = 7.72 Hertz, the closest genuine note to a 7.8 hertz frequency.
B flat note, C note, D note, E flat note, F note, G note, A note, B flat note.
1,000,000,000 Hertz=1 Gigahertz
The value in Hertz is the number of cycles per second - therefore the answer is 61. This note would be approximately equal to the third B below Middle C.
There are 15 million Hertz in megaHertz. It is spelled, "Hertz" because it was named after a person.
