What this choice changes

Nothing is cut off the top; the whole band goes out as recorded. Consonants and clarity sit in the middle, and the 14–19kHz tones are included (a band most adults no longer hear). The court music sits 18dB under the narration.

Age	Ceiling	Consonants	Clarity	Court music
Unborn baby (prenatal)	10kHz	off	0	-14dB
Under 5	12kHz	on	10	-16dB
Kids & students (6–19)	16kHz	on	30	-18dB
Adults (20–39)	no cut	on	50	-18dB
Midlife (40–64)	no cut	on	60	-19dB
Seniors (65+)	no cut	on	70	-21dB

That balance applies only under the narration. The 30-second intro and the court music behind the credits and review keep their own level.

Bands a baby should not hear are removed on the server.

Three jeongak pieces — tap to listen

These are what plays for five minutes after each story ends — geomungo, gayageum, daegeum. The piece you pick loops on its own; “Play all three” plays them in turn.
