Abstract

 Objectives: 1. To study the spectrographic picture of the infant cry due to different reasons after changing it into waveform. 2.To co-relate the waveform pattern  with  the cause. Study population: Babies of any sex between 0-8 weeks. Study design: Prospective cross- sectional Observational study . Methods: Babies in the postnatal ward were selected for recording of hunger (20) and discomfort cry (20). Whenever a baby cried the cry was recorded ,  diaper was checked If found soiled  was changed. if baby stopped crying it was labeled as discomfort cry. If diaper was dry, the baby was put to breast and if baby stopped crying it was labeled as a  hunger cry. Babies (20)for DPT immunization was recorded for pain cry. Record was taken 5-10 seconds from start.  Recording was done using APPLE I pod, software  using a microphone. The sound spectrogram was converted to pressure wave form using computer software ACOUSTIC ANALYSING SYSTEM 5E. Result : Total 60 babies were recruited between 0 to 8 weeks. Typical wave forms could be correlated with cause of cry. Conclusion: The sound spectrogram of infant cry  can be converted to pressure waveforms   which are typical and specific for the cause of cry. An instrument can be made which will record baby cry  and correlate it with cause.
