Concept of 3 Audio Frequency Range Bass – Mid – Treb

Sound engineers are too familiar with concepts related to audio frequencies such as Bass, Mid, or Treble but those who are just starting to get used to it. The definition of audio frequencies such as Bass, Mid, or Treble is still quite vague.

The nature of sound is mechanical vibration waves (usually considered in the air medium), and one of the most basic units of sound is frequency. The human ear can hear sound frequencies ranging from 20Hz to 20kHz (from 20 to 20,000 times/second). People often divide this audio frequency range into three basic frequency ranges: Bass, Mid, and Treble for easy identification. Frequencies beyond the 20Hz to 20kHz range are infrasound (lower than 20Hz) and ultrasonic (higher than 20kHz).

You should listen with a pair of pretty good speakers or more to fully feel this frequency range (if you listen to it with too poor quality computer speakers, you will find out that the frequencies are too low or too high. You won’t hear anything; that’s because the speakers you’re listening to aren’t capable of emitting those frequencies).

The first is the concept of 3 sound bands: mid, Bass, and treble.

Bass (bass sound)

The Bass frequency range is also subdivided into:

Low Bass (Deep Bass): ~ 20Hz – 80Hz

Bass: ~ 80Hz – 320Hz

Upper bass (High bass): ~ 320Hz – 500Hz

That is the frequency range that is most often misjudged in audio. Inexperienced listeners often confuse the “depth” and “intensity” of the Bass. Headphones with good Bass will show very low frequencies (Bass down very deep) even at a volume that is not too loud, no hum, no feeling of Bass being “pulled.”

Mid (midrange)

That is the most common frequency range in nature (human voices, ocean waves, cries of most animals, sounds in daily life); our ears are the most sensitive and the most sensitive, most accurate price in this frequency range. A Mid sound is considered good when there is clarity, detail, clarity.

Low mid: ~ 500Hz – 1kHz

Mid : ~ 1kHz – 2kHz

High mid : ~ 2kHz – 6kHz

Treble (high tone)

Having an audio frequency range stretching from about 6kHz to 20kHz (Just saying that, but the human ear hears it to 17kHz is called a good thing), the Treble sound contributes to increasing the detail, Brightness, and sharpness of all sounds. We hear music. Treble “good” will not be too “sharp” or harsh but will be pure. According to research by leading audio companies in the world, at ultrasonic frequencies (higher than 20kHz), people can’t hear it but still “feel” it, contributing to an increase in “emotion” when listening to music. As a result, headphones or speakers can emit extremely high frequencies, sometimes more than 40kHz.

The concept:

Airy: talk about the listening space and the ability to fly far and high of the sound. Often this high flying is the advantage of opened-back headphones.

Analytical: a term when talking about the ability to separate the parts, layers of a piece of music

Balance: adjective used to talk about a calibrated headset so that no band is superior, dominant, or louder than other sound bands.

Bassy: a headset called bassy is when the Bass from 200Hz or less is emphasized, with great intensity.

Bloat: adjective, often used to refer to the mid-bass sound of 250Hz excess, reverberated, um um.

Boomy: this is called rumbling Bass, buzzing Bass, 125Hz sound is redundant in volume, out of control

Bright / Brightness: often used to talk about the clarity and clarity of the high mids and highs. This definition of “bright” “clear” is not necessarily dazzling, so don’t be mistaken.

Congestion: one sound overlaps the other sticky sound.

Dark/ Dull: only headphones with unremarkable high mids and highs

Decay: used to evaluate the deposition rate of a piano finger, a guitar snap, the vibrato of a human voice.

Depth: depth of listening space

Details: The information contained is good or not, easy to listen to the small details in the song, concise and sharp.

Forward: most often seen when talking about the mid-range. That means that the mid-tone has a greater intensity than the other sounds.

Fun: an energetic sound with tight, powerful upper Bass that sounds louder than other sounds. The most obvious is a few headphones like AKG Y55, Philips A1 Pro.

Harsh: refers to harsh glare when high mids and treble are pushed too much, in the range of 2kHz to 6kHz. Harsh is not only a problem of headphones; it also occurs due to improper combinations, for example, amplifiers with high output impedance but mixed with low impedance headphones.

Imaging: sometimes we call it imaging, positioning, arrangement of instruments during use. Evaluating whether a headset has an accurate picture or not is an extremely difficult thing; listening to a lot of music, listening to many songs to get a common sound, and having a reference headset for comparison is necessary.

Lush: fullness, charm, warmth covering the overall sound.

Microphonics: conductors, light bulbs, absorb mechanical impacts such as knocks, flicks, wind blows. Do you wonder why the in-ears worn on the ears knock on the wire? That is the phenomenon of microphonics. As for the lamp, if the mechanical structure of the bulb is not good or loose, then when the fan blows in, we also hear a “cuckoo” sound extending from the speaker or headset.

Muddy: sounds blurry, not clear, you try to put cotton balls in your ears and then go to the street; the adjective “muddy” is that.

Openness: the openness, harmony between the depth and width and height of the listening space.

Sibilant: harsh, harsh sounds
