24dB Sound Pressure Level (SPL) is about the sound level in a calm room.
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.
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.
70-100 decibels
A meter is one meter.
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.
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.

Sound is measured in decibels by a sound pressure level meter (SPL-meter).
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.
You measure the sound pressure with a sound pressure level meter (SPL meter).
Varies from one to another.
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.
Pin dropped from a height of 1 centimetre heard at a distance of 1 meter would be ~15dB
