Painfully loud. Almost like the sound from sandblasting or a loud rock concert. 120 decibels is close to the pain threshold in human hearing, and yes sound can be painful.
That's pretty loud. Close to ear aching.
A noise level that measures 65 decibels is for a normal conversation on the noise scale. On this scale, 0 decibel is the threshold of hearing and 140 decibels is a jet plane at a distance of about 50 meters away.
decibels
Sound level meters are instruments that measure the sound pressure level. Sound level meters, or sound meters are commonly used in noise pollution studies, examples are industrial spaces, environmental spaces, and aircraft spaces.
131 decibles is extremely loud. The noise from the loudest sporting events is about 131 decibles.
Anything above 115 decibels is considered to be in the "pain/hearing loss" area.
A noise level that measures 65 decibels is for a normal conversation on the noise scale. On this scale, 0 decibel is the threshold of hearing and 140 decibels is a jet plane at a distance of about 50 meters away.

The noise of a fan can be measured in decibels using a sound pressure level meter. Knowing the level of noise allows people to classify as pollution or conducive.
Decibels
The unit for noise is decibels
dB is short for Decibel, or one tenth of a bel. Bels and decibels are unlike any other measurement, because an addition of ten means double the loudness of the noise. For example: 60 decibels is the noise generated from a regular conversation, however, 70 decibels is double the noise; and 80 is double that.
It depends on what organism is hearing the noise. For us humans, that would be 0 decibels.
A noise figure is a scale of decibels.
