Simple Explanation

The low end of the sound frequency spectrum, typically from around 20 Hz up to 150 Hz.

Concise Technical Definition

Bass refers to the portion of the audio frequency range encompassing low frequencies, generally between 20 Hz and 150 Hz, responsible for deep tones such as those produced by kick drums, bass guitars, or subwoofers.

Layman-Friendly Analogy

Like the rumble you feel in your chest during an explosion in a movie or the deep thump of a subwoofer at a concert.

Industry Usage Summary

In audio engineering and music production, managing bass frequencies is crucial for creating impact, fullness, and balance in a mix. These frequencies are often handled by subwoofers or dedicated bass drivers to avoid overwhelming mid and high frequencies.

Engineering Shortcut

Bass = 20 Hz to 150 Hz → use subwoofer or bass driver.

Full Technical Explanation

Bass encompasses the low-frequency audio range, usually from 20 Hz (just above the threshold of human hearing) up to about 150 Hz. These frequencies carry the power and depth in music and sound design. Proper management of bass is essential in room acoustics and system design to avoid muddiness or excessive boominess in playback environments.
