Hearing thresholds are defined for steady tones lasting over 100 ms

Evidence

The loudness percept requires some time to build up. The loudness level caused by a 2-kHz tone burst is shown in Figure 10.16. When the length of the burst decreases from 100 ms, the loudness decreases 10 phones each time the length is decreased to one tenth, indicating that the loudness percept is formed by integrating sound energy over time. This operation performed by our hearing is called temporal integration. For a sound burst lasting longer than 200 ms, loudness no longer increases (Fastl and Zwicker, 2007). — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1171 (#expands, via linked claim)
