In addition, sounds can also be long and soft as well as short and loud. [7] Onset time of the noise during the night: The ISCD-2 established latency of noises after falling asleep ranging from 2 to 6 h. [11] However, in some published cases the onset time of the noises is reported as being shorter (3 min [16]). Association with respiratory ...

[9] Overstimulation may be a contributing factor to infant crying and that periods of active crying might serve the purpose of discharging overstimulation and helping the baby's nervous system regain homeostasis.
