Absolutely. Photographic light meters are designed to measure light for photographic exposure (in a film-speed/shutter-speed/aperture combination), but many hand-held photo light meters can measure light in footcandles, which is a common scale. If you look on places like eBay, you can find inexpensive, digital, brand new meters which read out in Lux or Lumens. Some may read in footcandles as well. It's not difficult to convert from one measure to another (there should be internet calculators which would do it easily).
No, decibels are not used to measure light. Decibels are used to measure sound and volume.
Hertz is used to measure sound frequency (how high or low the sound is). Decibels are used to measure how loud or soft a sound is.
Decibels are a logarithmic measure of a factor or a ratio and that has really nothing to do with metric or imperal.
by loudness decibels by frequency hertz by wavelength any power of meter
decibels
That depends how close you measure to the speaker. The closer - the louder! The distance is very important if you measure with a sound pressure level meter. In 1 meter distance the sound pressure level is arround 60 decibels SPL.
decibels measure the intensity of sound.

That is commonly measured in decibels.
Hertz is used to measure sound frequency (how high or low the sound is). Decibels are used to measure how loud or soft a sound is.
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.

yes it dose because I looked in my science
Take a sound pressure level meter (SPL meter). Try to measure the sound pressure p in pascals or in decibels, referred to the threshold of hearing with 20 micropascals.
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.
