An audio frequency or audible frequency (abbreviation: AF) is a periodic vibration whose frequency is in the band audible to the average human, the human hearing range. The SI unit of frequency is the hertz (Hz). It is the property of sound that most determines pitch. The generally accepted standard hearing range for humans is 20 to 20,000 Hz.


Audio Spectrum Explained. The audio spectrum is the audible frequency range at which humans can hear. The audio spectrum range spans from 20 Hz to 20,000 Hz and can be effectively broken down into seven different frequency bands, with each having a different impact on the total sound. The seven frequency bands are:


Frequency Chart – The Most Important Audio Frequency Ranges The “perfect” human ear can hear frequencies ranging from 20Hz to 20.000Hz (or 20KiloHz/Khz) according to the official frequency chart. The average hearing range of the human ear though can hear from 50Hz to 16Khz. The lower the Hz the bassier the sound.


Hearing range describes the range of frequencies that can be heard by humans or other animals, though it can also refer to the range of levels.The human range is commonly given as 20 to 20,000 Hz, although there is considerable variation between individuals, especially at high frequencies, and a gradual loss of sensitivity to higher frequencies with age is considered normal.


The entire frequency spectrum consists of sound waves, electromagnetic waves and light waves. A rough classification characterizes the range above the sound waves between 30 kHz and 300 MHz as high frequency, the frequency range between 300 MHz and 300 GHz as microwaves and the overlying range between 300 GHz and 400 THz as infrared, followed ...


Frequency response is the most important part of audio reproduction. For the most part, the perceived subjective sound quality of a speaker can be predicted from its frequency response 1,2,3,4. It describes how accurately a system reproduces each frequency of audio content in terms of amplitude.


Vocal EQ’ing can be frustrating.Sometimes it seems to sound like it was stuck on later, and doesn’t flow with the rest of the track. Below are the six frequency ranges you can start with when you are in trouble and need to figure out how to equalize your vocal so that it sits better with your song.


By recognizing what certain frequencies sound like, you’ll become faster and more effective at EQ’ing your mixes. 50 Hz. The lowest frequency range adds fullness to those bass instruments like the kick drum, toms and bass. Cut in the 50 – 100 Hz area if they are getting too thick and interfering with the clarity of the low-end of your mix.


Tech Stuff - Frequency Ranges. One of the earliest techniques one stumbles accross in the manipulation of Audio is the concept of equalization (EQ), both when mixing multiple tracks to create an audio output or when trying to fix up existing recordings. Equalization allows all kinds of magic such as the ability to pull out voice from a lot of ...
