Production claim

Does a louder master sound better?

Louder wins in a direct comparison and loses once streaming normalisation removes the advantage.

Updated 2 min read 10 citations

What the evidence actually shows

Listeners reliably prefer the louder of two otherwise identical presentations, which drove decades of escalation. Loudness normalisation on streaming platforms removes that advantage while the dynamic-range cost remains. [1]

The better-designed studies point away from this claim. It survives because it is intuitive, or because early weak findings were widely repeated before stronger work arrived.

Loudness is graded "contradicted". These claims are marketed with roughly equal confidence; this is the same list sorted by what actually supports them. Grading: our reading of the cited literature, not a formal GRADE assessment.

The catch

Normalisation targets differ between platforms, so a master optimised for one is not optimal everywhere — but over-compression is penalised across all of them.

Not supported. Listeners reliably prefer the louder of two otherwise identical presentations, which drove decades of escalation. Loudness normalisation on streaming platforms removes that advantage while the dynamic-range cost remains.
What is the main misunderstanding about loudness?
Normalisation targets differ between platforms, so a master optimised for one is not optimal everywhere — but over-compression is penalised across all of them.
How confident should I be in this?
The better-designed studies point away from this claim. It survives because it is intuitive, or because early weak findings were widely repeated before stronger work arrived.

What we are not claiming

This is general information drawn from published research, not advice about you specifically. Effect sizes in free-living people are usually smaller than headlines suggest, and an average across a trial population may not describe you.
