In one meter distance the hairdryer can be 60 dBSPL.
Never forget to tell the distance of the measuring microphone from the the hairdryer , because the closer you are to the the louder it is.
The sound pressure level decreases by 6 dB per doubling of distance from the source to 1/2 (50 %) of the sound pressure initial value.
The sound pressure decreases inversely as the distance increases with 1/r from the sound source.
A hairdryer typically emits sound at around 70-90 decibels. The noise level can vary depending on the specific hairdryer model and its settings. Excessive exposure to high decibel levels can potentially damage hearing over time.

A whistle can produce a sound ranging from 90 to 120 decibels, depending on the design and force blown into it.
Thunder can reach up to 120 decibels at close range, which is equivalent to the noise level of a chainsaw.

20 decibels
207 decibels.
70-100 decibels
in what
20 to 50 decibels (dB).
85 decibels maximum.
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
a plane has 15000 decibels, there are lots maybe upto 2000000
