20 to 50 decibels (dB).
To calculate the number of decibels that power-level-'A' is greater than power-level-'B',-- Divide 'A' by 'B'-- Take the 'log' of the quotient-- Multiply the 'log' by 10 .If the result is negative, then 'A' is that many decibels lower than 'B'.
Decibels are a logarithmic way of expressing a magnitude, megahertz is a frequency. Specifically, 1 megahertz = 10^6 cycles/second There is no answer to the question.
Decibels
The decibel level for standard human voices is around 60 decibels, which is also the level for singing birds. Hearing loss occurs at around 110 decibels with painful hearing loss occurring at 130 decibels.
A drum kit is no decibels. The decibels depends how close you measure to the bat. The closer - the louder! And the louder you play the more decibels you get. The distance is very important if you measure with a sound pressure level meter.
20 decibels
207 decibels.
70-100 decibels
20 to 50 decibels (dB).
85 decibels maximum.
in what
Bats are mammals and in many languages, the word bat is replaced with the word mouse. In Russia they call the bat a flying mouse.
130 decibels -140 decibels close up maybe louder though
Roughly 150-160 decibels.
50 phons (decibels) is equivalent to 2 sones.
•Sound can be measured in many ways such as decibels. There is a special machine which you can by that measures how many decibels something makes. A pin makes 10 decibels where as a loud persons or a stereo can make up to 80 decibels. Volume is measured in decibels. So Frequency is measured in hertz
