Decibels (dB) mean a logarithmic unit of measurement that expresses the magnitude of a physical quantity relative to a specified or implied reference level. Since it expresses a ratio of two quantities with the same unit, it is a dimensionless unit. Decibel is Decibel!

How many decibels does a cough produce?
70-100 decibels
You want to measure how much louder 95 decibels is than the threshold of sound?
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.
Normal conversation is usually about decibels while noise at decibels or higher can start to damage your hearing?
65; 85
How many decibels is a blender?
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.
Is it true that the loudness of different sounds is compared in units called hertz?
No.. hertz relates to the frequency (pitch). The volume of a sound is measured in decibels.
What is the different between positive and negative decibel?
Negative decibels mean damping (loss) and positive decibels mean amplification (gain).
Sound is measured in what types of unit?
Sound is measured in decibels, which are commonly shortened to "dBs".
Why is the abbreviation for decibels dB?
DeciBels
Does voltage current or power affect volume in a speaker?
Power (Watts)/ Decibels (if the speaker is efficient) 2 Watts = 93 decibels 4 Watts = 96 decibels 8 Watts = 99 decibels 16 Watts = 102 decibels 32 Watts = 105 decibels 64 Watts = 108 decibels 128 Watts = 111 decibels 256 Watts = 114 decibels 512 Watts= 117 decibels 1024 Watts = 120 decibels Some Volumes to Compare 10 decibels = normal human breathing 60 decibels = normal human conversation 110 decibels = power saw, car horn, shouting in ear, 120 decibels = jet aircraft close by, emergency vehicle siren, rock concert
