The intensity of sound is most often measured by the Decibel meter. It can also be called the sound level meter or the dB Meter. It is used to accurately and objectively measure the sound or noise that one can hear.

What instrument measures sound intensity?
An oscilloscope measures electrical signal amplitude and wavelength. A decibel or sound-level meter. A cheap one is available at your local Walmart for about $20 located in the car audio section. If not instore, online. They make much better ones, but if you are looking to just get a rough idea, this is the way to go.
What sound intensity level would you expect to be painful to most humans?
120 decibels
Which wave characteristic is most related to sound wave intensity?
Amplitude (the height of the wave)
How will decreasing the amplitude of the sound waves from a TV affect its intensity?
Amplitude is intensity. It refers to the strength of a sound wave, which the human ear interprets as volume or loudness and if you decrease the amplitude you also decrease its intensity.
Determined by the amount of energy a sound wave carries?
A radio going in the background will be radiating a few tens of milliWatts of sound from its speakers. [Loudspeakers are rather inefficient, particularly so for high quality ones. 10% would be a good figure, - perhaps 3% for a high quality one.] So a say 60 Watt (RMS) amplifier and appropriate speakers; which would sound really loud; would be radiating a few watts of sound.
Unit of sound intensity?
The unit of sound intensity I is watts per meter squared (W/m²). Sound intensity is a sound energy quantity. Sound pressure deviations are moving our eardrums. The unit of sound pressure p is pascals (Pa) or newton per meter squared (N/m²). Sound pressure is a sound field quantity. Another answer: The most common unit of sound intensity is the decibel (dB). Reply: No! We got the sound intensity measured in W/m² and the sound intensity level we measure in decibels (dB). The question was "sound intensity".

What do you mean by intensity value?
The word "intensity" can be synonymous with "strength", "amplitude", or "level", as it sometimes is in colloquial speech. It is possible to define the intensity of the water coming from a garden sprinkler, but intensity is used most frequently with waves - i.e. sound or light.
What is the most important use for a spectroscope?
a spectroscope is used to measure light waves. It can measure lights intensity, wavelength, and it polarization.

Hertz.

How big can thunderstorms get?
Thunderstorms can reach a height of 65,000 feet or more. However, meteorologists do not measure thunderstorms by height alone, but by intensity. This is most often determined by the storm being strong enough to inflict wind or hail damage.
What is the name of the instrument used to measure the intensity of a tornado?
In most cases the intensity of a tornado is never actually measured. Tornadoes are rated based on the severity of the damage they cause. Mobile Doppler radar can measure wind speeds in a tornado, but since such radar cannot measure ground-level winds the measurements are not used in ratings.
