Here's a scale:
10 dB: leaves blowing in the wind
20-40 dB: a regular run-of-the-mill computer
30-60 dB: a server (like the big professional company ones. My Dell poweredge server weighs in at about 55-65 dB depending on temps and load)
75-95 dB: a car
85 dB: Here it starts damaging your hearing. Most MP3 players have a software limit at this level, ie. highest setting.
~ 100 dB: a motorcycle, Harley Davidsons and choppers are louder than this.
110 dB: a rock concert
120 dB: a jet airplane taking off (props are louder)
>200 dB: a nuclear blast from 2 km away. If you didn't burn to death, your eardrums would vaporize and even kill you because of the sheer sound pressure.
Decibels
Yes it is.
yes, and it is measured in decibels
A noise level of 65 decibels is equivalent to the sound of a normal conversation or background music in a restaurant. It is also the recommended noise level for a comfortable working environment.
At 55 decibels, the noise level is considered moderate and similar to a quiet conversation or background music.
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.
A noise level of 65 decibels is considered moderately loud, comparable to the sound of a normal conversation or background music in a restaurant. Continued exposure to noise at this level can lead to hearing damage over time. It is important to protect your hearing by using ear protection in environments with sustained noise levels at or above 85 decibels.
The maximum allowable noise level in a residential area is typically around 55 decibels. This is considered the threshold for acceptable noise levels in residential areas.
A noise level of 70 decibels is equivalent to the sound of a vacuum cleaner or a busy street. It can be considered moderately loud and may be disruptive to some activities requiring concentration or quiet environments.
The loudness or volume of music is measured in decibels. Decibels are a unit used to quantify the intensity of sound.
The recommended noise level for a quiet office environment is typically around 55 decibels (dB).
•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
