Envelope-structured sounds produce time-variant temporal masking patterns.

Evidence

Temporal masking patterns can be produced by maskers with a pronounced structure of the temporal envelope. Amplitude modulated tones or noises, frequency modulated tones, or the envelope fluctuation of narrow-band noise represent typical examples for sounds producing time-variant temporal masking patterns. — Professor Dr.-Ing.
