•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

A noise level of 65 decibels is measured for?
A noise level of 65 decibels is considered moderately loud, comparable to the sound of a normal conversation or background music in a restaurant.

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
How many decibles are waves?
Wave intensity is typically measured in decibels (dB). The decibel scale is logarithmic, so the exact value of the decibels for waves would depend on the intensity of the wave. Generally, normal conversations are around 60 dB, while a jet engine may be around 140 dB.
