Many kinds of instruments measure signals in decibels (dB). Since dB represents nothing more than a log ratio of two quantities, anything that can be quantized could be measured in dB. The most common things measured that way, however, are: * Sound Levels (an SPL Meter)
* Electrical power levels (a Network Analyser, a Spectrum Analyser, Power Meters)
* Light levels (an Optical Spectrum analyser or Power Meter). Note that dB is always a relative term, however figures are often quoted with respect to some reference such as 'dB(SPL)" used for sound where the reference is the quietest sound a human can hear, or dBm for electrical power where the reference is 1 mW.

What is a machine that measures decibels?
An SPLOIUYTR machine measures decibels.
What unit are sound waves measured in?
•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
What is the logarithmic scale that measures sound level?
deciBels
What instrument measures decibels?
Most famous is a SPL meter (Sound Pressure Level).
