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
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.
I have a new blender at home that I think is relatively quiet for a blender. I have measured the noise from it with my iPhone as apparently only 60 decibels when standing at a distance of 1 meter away while I was blending fruits with it. Due to this, I think that there is a very large range in the noise levels of different blenders because I have heard people claim that other blenders were 90 decibels at a distance of 1 meter and I only measured my blender as being 60 decibels at that same distance. That is a difference of 30 decibels, which is a huge difference considering that the decibel scale is logarithmic. I think that the newer blenders are probably much quieter than the older blenders were.
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.
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.

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).
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.
Varies from one to another.
Pin dropped from a height of 1 centimetre heard at a distance of 1 meter would be ~15dB
That depends how close you measure to the elephants mouth. The closer - the louder! The distance is very important if you measure with a sound pressure level meter.
