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.

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)
How does a sounds frequency relate to a sound's pitch?
The pitch and frequency are the same thing. The term "pitch" is used by musicians while the term "frequency" is used by scientists. By Lorraine Kyle B. Vergara
What type of sound is heard when th sound waves are vibrating slowley?
Pitch is affected by the frequency and wavelength of a sound wave. When the frequency is lower there are not as many waves per second, and the wavelength becomes longer. A low pitch is made by the low frequency and long wavelength of a sound wave.
How does an electro magnet work in a speaker?
The electromagnet is used to vibrate the diaphragm of the speaker and a given rate (frequency) to produce a given sound.
Which wave property is related to how loud or soft a sound is?
The pitch is determined by the frequency of the wave.The absolute loudness is determined by the wave's amplitude.The loudness perceived by the ear is affected by both the above, because the sensitivity of the ear is frequency dependent.
What term is used to indicate the frequency level of sound?
a. pitch
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 equipment do you used to measure sound?
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.
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 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.
