okay since theyre not related... what is the frequency of jackhammers in HERTS not decibles??
2007-02-12 13:08:15 · update #1
get a clock and count how many hammers you hear in 1 second and that is how many hertz you have (roughly) as a hertz is a cycle per second.
as for dB levels , a jet aircraft is 133dB at 33meters or 100dB at 170meters. now considering the dB scale is exponential l`d say your jackhammer was no more than about 110 dB if you were stood next to it

It depends on the line pressure and the hammer throw. Usually somewhere between 5 and 15 Hz.
As far as giving it in Hertz, it's about the same as the number of liters in a kilometer.

Well, I'm afraid that they aren't actually related... Hertz is a unit of Frequency and Decibels is a unit of sound pressure (or amplitude).
Its a bit like asking how many liters in a cucumber.

you can convert Watts into db by using the following conversion
y=10*log10(WATTS)
or you can convert a input of Volts into power
since P=(V^2)/R...
then you have
y=10*log10*(abs(u)^2/R)
but Hertz=cycles/second...you can't convert a measurement of power into Hertz....
