A new baby-alarm based on tenseness of the cry signal.
Present-day conventional baby-alarms for hearing-impaired parents do not convey information about how the baby is feeling (happy, crying, or distressed). Consequently, the parent is forced to go to the baby to weigh up the situation visually. A new baby-alarm, FreDe 85, which determines the tenseness of the cry signal, has been tested by 10 deaf families with babies in the age range 3 to 21 months. The test families compared the illuminated pictures on the panel of the baby-alarm with the baby's situation. The parents could observe significantly different distributions of illuminated pictures in the three situations. Some families living in multi-storey flats experienced false alarms in the night, indicating the need to place the microphone closer to the baby.
