All levels are measured in decibels (dB). Sound level means always sound pressure level.
There is the most important sound pressure level SPL, measured with a SPL meter.
There is the particle velocity level.
That are sound field quantities.
There is the sound intensity level.
There is the sound power level.
There is the sound energy density level.
That are sound energy quantities.

Indicate the frequency level of a sound?
Frequency is usually not measured in "levels" (though the sound pressure or volume is) Frequency is measured in Hz (Hertz) or vibrations per second. Sound pressure is measured in Decibels
How loud a sound is depends on the wavelength of the sound?
The level of the sound or the amplitude of the sound has nothing to do with the wavelength. Speed of sound c = wavelength λ × frequency f.
The pitch of a sound is the distance from the sound source?
The pitch of a sound means the frequency. That stays constant with distance. You mean the sound pressure level that decreases with distance.
What is the difference between loudness and frequency?
loudness is the level of sound source while frequency define the repitition rate of that sound source. NAVNEET KUMAR,SRFTI,KOLKATA, email add: kmr_verma@yahoo.com
How i can measure sound frequency from sound level meter?
You just need a meter that measure Hertz (high and low) as well as db (volume)

What term is used to indicate the frequency level of sound?
a. pitch

The pitch of a sound means the frequency. That stays constant with distance. You mean the sound pressure level that decreases with distance.
What are hearing ranges measured in?
There are two parameters regarding hearing ranges. One is frequency range, and the range of hearing is measured in Hertz, which is cycles per second. Another variable is the threshold of hearing. In other words, how loud does a sound at a given frequency have to be to be heard. That sound level is measured in decibels with respect to a reference level. The threshold level will vary with the pitch (frequency) of the sound, as you might have guessed.

loudness is the level of sound source while frequency define the repitition rate of that sound source. NAVNEET KUMAR,SRFTI,KOLKATA, email add: kmr_verma@yahoo.com

Do sound waves increase or decrease above sea level?
The sound has really nothing to do with sea level, but changes with temperature alone. The speed of sound goes up when the temperature goes up and goes down when the temperature goes down. The frequency of sound columns, like of woodwinds or of church organs changes with temperature. If the temperature increases, the frequency increases also.
What is the unit for measuring the relative intensity or loudness of sound?
Loudness N is measured in in sones.Loudness level LN is measured in in phons.Sound pressure level is measured in dBSPL, where the reference level of 0 dBSPL is the threshold of hearing.The ear drums and the microphones are only sensitve to the sound pressure.We measure the sound pressure with a sound level meter.Loudness is affected by sound pressure, frequency and its bandwidth, and duration (time).Usually sound is measured in Decibels.
Which characteristic of sound depends upon frequency?
frequency is the pitch of a sound
What does the frequency of sound measure?
The frequency of sound is measured in "Hertz (Hz)".
What is the sound of glass smashing measured in decibels?
It is not so much the volume of the sound as the frequency as well. Sound at the wrong frequency can be played as loud as you like and it will not break the glass. The sound needs to be the same frequency as the resonant frequency of the glass (tap the glass, that note is it's resonant frequency). Once the resonant frequency has been found, it does not take much volume at all, even humans can do it, albeit trained singers (see Mythbusters).
