Is Sony DSGX same as Loudness control?
|
They're related, but not exactly the same.
Loudness control (traditional hi-fi feature):
- Designed to compensate for human hearing at low volume.
- Our ears are less sensitive to bass and treble when sound is quiet (Fletcher-Munson curves).
- The loudness button boosts bass and sometimes treble only at low listening levels to make music sound more balanced.
- At higher volume, the effect becomes less necessary.
Sony DSGX (Dynamic Sound Generator X-tra):
- More of a fixed sound enhancement mode than a true loudness compensation.
- Adds extra bass punch and clearer highs/vocals regardless of volume.
- Doesn't dynamically scale with volume the way a true loudness circuit does.
- It's closer to a bass boost + clarity enhancer than a psychoacoustic loudness control.
Would you like me to break it down with an example frequency curve (what gets boosted and where) so you can see the difference visually?

yes

Here's a visual comparison:
- Flat (dashed line): No enhancement.
- Loudness control (blue): Boosts bass and treble moderately, mainly to make quiet listening sound fuller.
- Sony DSGX (orange): Applies a stronger, punchier bass boost and a more noticeable high-frequency lift, regardless of volume.
So DSGX is like a more aggressive, always-on version of loudness rather than true volume-dependent compensation.
