What is an equalization? 

An equalization is carried out by means of a processor that allows certain frequency ranges to be increased or decreased to modify or improve the sound quality. It usually works with frequencies between 20 Hz and 20,000 Hz, which theoretically are what humans hear, although in reality this range can be reduced by age and other factors.

Nowadays audio is mostly consumed digitally, therefore, equalizers have been implemented in most modern devices, to allow you to adjust settings and get the most out of your speakers. 

What function does an equalizer serve? 

What function does an equalizer serve?

The equalizer adapts to your listening preferences and allows you to restore great sound that is often interrupted by its loudest and most difficult to manage component: the car. Vehicle noise, road noise, the size and shape of the car interior, the reflectivity of the glass, and the absorbent nature of the seats all affect the sound of the system.

You can use an equalizer to remedy each of these irregularities, increasing the frequencies that are missing and attenuating those that your vehicle exaggerates.

An equalizer is also a great way to protect your equipment. For example, if your system's bass is provided by a pair of 6-1/2" woofers, you can use an equalizer to reduce all frequencies below 50 Hz. The amplifier will run more efficiently and you'll get louder, cleaner volume while protecting the speaker drivers from tones they can't handle. 

Tips to follow an ideal equalization 

Understanding frequency ranges is crucial to using audio equalization settings. Here is a quick breakdown of the different frequency ranges so you can achieve the best sound: 

Subwoofer (20-60Hz)

These are the bass frequencies found in kick drums and subwoofers. You need a decent pair of headphones or a subwoofer to hear these frequencies. 

Low-Mids (60-250Hz)

These are the low frequencies that provide fullness and warmth in a mix. You'll find bass in this range, as well as the lower frequencies on guitars, vocals, synthesizers, and keyboards. 

Mids (250 Hz-1.5 kHz)

Most instruments are found in the mid-range frequencies, including guitars, pianos, and vocals. 

Upper Midrange (1.5-6.6kHz)

The human ear picks up upper midrange frequencies more than anywhere else, so taking care of them requires finesse. They are necessary for presence, although they can easily sound harsh if there are too many of them. 

Treble (6.6-20kHz)

Here you'll find the sparkle found on vocals, cymbals, acoustic guitars, and other instruments. While brightness is important in any mix, it also requires care, as too much can sound strident.

How to get the perfect equalization?

EQs are usually set flat so you can hear the sound as it was originally recorded. However, you can always improve the audio experience by modifying the settings according to the music genres you are currently listening to. 

These are some examples, according to some musical genres: 

Equalization for each musical genre 

  • Acoustic: It pumps up the lows, mids, and upper mids a bit to boost vocals and the sound of most instruments. 
  • Electronic: The bass is super important and since it is often not focused on the vocals, you want to get the most out of the digital sounds in the high ranges. 
  • Latina: It has to do with bass and treble, with strong voices that normally do not require more boosting. 
  • Pop: This is mainly vocals and mid-range sounds. So increase these frequencies and a little bit the low-mid and high-mid frequencies. 
  • Rock: It focuses a lot on the low frequency sounds and the high frequency sounds of electric guitars.
