Letter to Editor
I have read the case report entitled “Measurement of Noise Levels in a Hospital Neonatal Unit in Costa Rica” by Juan, CO, Paula, SC, and Carolina, MN published in the Global Journal of Otolaryngology (2019; 19(4): 556018). I want to congratulate the authors for this important work and contribute regarding the conclusion.
It was indicated noise levels exceeding 80 decibels do not have potential intensity to cause noise-induced hearing loss. The World Health Organization globally recommended daily average exposure limit to prevent noise-induced hearing impairment is 70 decibels .
Although it was not the focus of this case report, sound pressure levels inside incubators may also exceed American Paediatric Association recommended noise level limits [2,3].
