That depends how close you measure to the fan. The closer - the louder! The distance is very important if you measure with a sound pressure level meter.
70-100 decibels

Take a sound pressure level meter and measure it. 95 decibels means over the is 0 decibels is the threshold of hearing. 95 decibels means the measure over 0 decibels.
That depends how close you measure to the mouth speaker. The closer - the louder! The distance is very important if you measure with a sound pressure level meter. A conversation in 1 meter distance may have 60 decibels.
65; 85
deafning sounds begins at 170 decibels
Depending on the plane and distance, more than 100 decibels.
180 decibels is the loudest. only if all equiptment is on at the same time.
•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

It depends on what organism is hearing the noise. For us humans, that would be 0 decibels.
