title: Simulation of prenatal maternal sounds in NICU incubators: a pilot safety and feasibility study.
abstract: OBJECTIVE
  This pilot study evaluated the safety and feasibility of an innovative audio system for transmitting maternal sounds to NICU incubators.
  
  
  METHODS
  A sample of biological sounds, consisting of voice and heartbeat, were recorded from a mother of a premature infant admitted to our unit. The maternal sounds were then played back inside an unoccupied incubator via a specialized audio system originated and compiled in our lab. We performed a series of evaluations to determine the safety and feasibility of using this system in NICU incubators.
  
  
  RESULTS
  The proposed audio system was found to be safe and feasible, meeting criteria for humidity and temperature resistance, as well as for safe noise levels. Simulation of maternal sounds using this system seems achievable and applicable and received local support from medical staff.
  
  
  CONCLUSIONS
  Further research and technology developments are needed to optimize the design of the NICU incubators to preserve the acoustic environment of the womb.
