Indeed a review by Konkani and Oakley reveals that ambient noise levels in typical NICUs can exceed 80 dB SPL [16].
Exceedance levels ([L.sub.n]) are calculated in addition to [L.sub.Aeq]; specifically, [L.sub.10] is the sound level exceeded 10% of the time, giving an approximate range of peak noise levels, while [L.sub.90] is the sound level exceeded 90% of the time, giving an approximate range of ambient noise levels. Unfortunately, the material and environmental changes that were originally planned to the hospital ward under study were not fully implemented, which limited the significance of this project's findings regarding the benefit of the intervention.
Ambient noise levels were measured at different locations selected on the basis of land use such as silence, heavy traffic and residential and commercial zones.
Once ambient noise levels reach certain amplitude they can possibly cause the hearing threshold for one sound to be raised by the presence of another--the process known as masking (Richardson et al.
