Amplitude-modulated loudness directly increases perceived fluctuation strength

Evidence

The fluctuation strength also depends on loudness. For example, a change in the level of amplitude-modulated sound from 50 dB to 90 dB causes a fivefold increase in fluctuation strength. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1223
