In science, sound frequencies, like frequencies in general, are reported in hertz (Hz), kilohertz (kHz), etc. In music, these sound frequencies correspond to notes (A-G) and different octaves. From Wikipedia:
The note-naming convention specifies a letter, any accidentals (sharps/flats), and an octave number. Any note is an integer of half-steps away from middle A (A4). Let this distance be denoted n. If the note is above A4, then n is positive; if it is below A4, then n is negative. The frequency of the note (f) (assuming equal temperament) is then:f = 2n/12 × 440 Hz
For example, one can find the frequency of C5, the first C above A4. There are 3 half-steps between A4 and C5 (A4 → A♯4 → B4 → C5), and the note is above A4, so n = +3. The note's frequency is:f = 23/12 × 440 Hz ≈ 523.2511 Hz.
To find the frequency of a note below A4, the value of nis negative. For example, the F below A4 is F4. There are 4 half-steps (A4 → Aâ™4 → G4 → Gâ™4 → F4), and the note is below A4, so n = −4. The note's frequency is:f = 2−4/12 × 440 Hz ≈ 349.2290 Hz.

What is the unit used to mesure the frequency of sound?
The unit used to measure the frequency of sound is hertz (Hz).
The term is used to indicate the frequency level of a sound.?
Tough one! You see, there is a term for both thefrequency and the level. The most common term for the frequency would be the "Pitch" of the sound, and the frequency unit of measurement is the Hertz (cycles per second) or Hz. It is an accepted standard that the average Human can hear a spectrum from 20Hz (really low pitch) to 20kHz (really high pitch). The level of sound is commonly referred to as the "Loudness" and is measured in Decibels (db) and the most common measuring device is called an SPL (sound pressure level) Meter. So...If you were describing, lets say, a very loud "A" note above middle "C", the description could look like this; 440Hz @ +110db. Dave Bowling (db)
What tools are used to measure sound?
Tools used to measure sound include sound level meters, which measure the intensity of sound in decibels, and spectrum analyzers, which show the frequency components of sound. Other tools include acoustic calibrators for calibrating the measurement equipment and noise dosimeters for monitoring sound exposure over time.
How is sound messured?
Frequency is the number of wavelengths produced in one second.
What is decibel and how is it used as a measure of the loudness of sound?
A decibel is a unit used to measure the intensity or loudness of sound. It is a logarithmic scale that compares the sound pressure level to a reference level. The higher the decibel level, the louder the sound.
What term is used to indicate the frequency level of sound?
a. pitch
How can you convert sound pressure level to frequency?
Convert in coming signal to D.C. using a bridge rectifier. Use the voltage to run a voltage to frequency converter. You will have to scale the incoming signal to match the frequency range desired.
What is the unit used to mesure the frequency of sound?
The unit used to measure the frequency of sound is hertz (Hz).
What should I know about parametric equalizers?
Parametric equalizers are electronic devices which let a person adjust the level and frequency of a sound. These devices are used by audio engineers in sound recordings.
What unit is used to express the intensity of sound?
decibel
What is the frequency of the ultrasound compared to the sound?
Ultrasound cannot be heard as it has a higher frequency than audible sound, with a frequency above 20000Hz.

What is pitch in relation to sound?
Pitch is often used to represent the frequency of a sound in music. It is distinguished from frequency though, because pitch involves how a human perceives that sound.
What tools are used to measure sound?
Tools used to measure sound include sound level meters, which measure the intensity of sound in decibels, and spectrum analyzers, which show the frequency components of sound. Other tools include acoustic calibrators for calibrating the measurement equipment and noise dosimeters for monitoring sound exposure over time.
What is frequency compensation?
Frequency compensation is a technique used in amplifiers. It basically controls the sound of the amplifier to make it sound clear and free of positive feedback.
What is the duplex theory?
The Duplex theory provides an explanation for the ability of humans to localise sounds by time differences between the sounds reaching each ear (ITDs) and differences in sound level entering the ears (interaural level differences, ILDs). The duplex theory states that ITDs are used to localise low frequency sounds, in particular, while ILDs are used in the localisation of high frequency sound inputs.
