Noise is masked more easily by tonal parts than tones are masked by noise

Evidence

Tonality has also been studied in the context of audio technologies and speech transmission, since knowing how well a partial of a harmonic or noise masks another partial or noise is relevant in audio coding (Johnston, 1985). It has been found that noise is masked easier by a partial than vice versa. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1246
