Care interventions to help reduce noise include: • Education of staff and parents about effects of sound and need for quiet(within limits of medical needs). Information posters. • Regular audit of of unit noise levels – diffent times of day, ward rounds and handovers, feedback to Staff/Parents. • Close incubator doors softly • Avoid placing objects on top of incubator • Silence alarms as soon as practicable • Set alarms and phones at lowest safe level • No radios in unit (age appropriate musical toys may be individually appropriate for post term infants). • Consider ear muffs during excessively noisy procedured – MRI.
