EEG waves {delta wave} can have frequency range 1 Hz to 4 Hz. If sound is during REM-sleep delta-wave activity, no coherent 40-Hz oscillations begin [Creutzfeldt and Houchin, 1984] [Creutzfeldt, 1995] [Freeman, 1975] [Mountcastle, 1957] [Mountcastle, 1998] [Remond, 1984]. Delta-wave frequency increases until one year old.
