What is the difference between negative and positive sound frequencies?

125 views

What do the frequencies on either side of the spectrum do and how should I know if I want my bass/ mid/ treble in the negative or positive?

Edit: Thank you for the answers. I realized that my question wasn’t very clear because I wasn’t too sure what exactly it is I was looking for. I did get the answer that I was looking for though 🙂

The frequencies aren’t negative but some sound systems let you adjust the strength of sounds at some frequency ranges to make then more loud or quiet. The amount of adjustment is shown using numbers with zero meaning no change, positive numbers meaning more loud, and negative numbers meaning more quiet.

For relatively small numbers of settings, like bass, mid and treble controls, your choice is mostly down to personal preference, but start from all zero as the default. Sophisticated systems can have separate controls for up to around 20 different frequency bands but setting all those is often done based on measurements of how the system and the listening environment are affecting the sound. If your speakers or room are making a particular frequency sound too quiet then you can turn up its control to compensate.
