That depends how close you measure to the bat. The closer - the louder! The distance is very important if you measure with a sound pressure level meter.
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
That depends how close you measure to the mouth of the human speaker. The closer - the louder! The distance is very important if you measure with a sound pressure level meter. At 1 meter distance the speaker may be measured at 60 decibels SPL.
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
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.
20 to 50 decibels (dB).
85 decibels maximum.
in what
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
