•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

If you take 80% of 80 dollars away, you are left with 16 dollars.

It is difficult to be specific because busy street traffic and quiet radio are not standard volumes of sound.However, a quiet radio - at around a "normal" conversation level is 60 decibels (dB). A busy street is can range from the low 70 to high 80 dB. Let us say 80 dB.The difference is 20 dB = 2 Bels. This means the street is 10^2 = 100 times as loud.

To solve this, you have to start with the whole of 80, and then take away 95% of 80, or (.95 x 80). 80 - (.95) x 80 = 4 Alternatively, you could do a bit of quick mental algebra to speed it up: 80 - (.95)(80) = 1 x 80 - .95 x 80 = 80(1 - .95) = 80(.05) = 4 Since you take away 95%, you're left with 5%.

That depends on the size of the donkey. I would expect a 14hh donkey in a quiet area to be able to call to another 3 miles away.

They range from 80 to 110 db, depending on the type or cap and the distance from the ear its being measured to.

80 decibels

40 dB gain change should give about the ratio of 16 for sensed volume and loudness, 40 dB gain change gives the ratio of 100 for measured voltage and sound pressure and 40 dB gain change gives the ratio of 1000 for calculated sound power and acoustic intensity. Go to the link: Subjectively perceived loudness (volume), objectively measured sound pressure (voltage), and theoretically calculated sound intensity (acoustic power).

Typically, the loudness of a sonic boom may exceed up to 200 decibels or higher, depending on the rate and the distance in which the sound barrier is being broken through. To make sense of this figure, the volume of busy traffic during rush hour is around 80 to 90 decibels.
