Hi there There are no prescribed limits. What is deemed "acceptable" depends on where the noise is occurring any why. As an example my wife runs a preschool and its operations are overseen by Social Services who would offer an opinion on noise limits but I have never seen any published figures in the "minimum standards" they issue. I do know that infants and young children are very susceptible to hearing damage. Hope this helps a little.

And there was me thinking from the title that you were referring to adult exposure to the little 'dears' screaming their heads off!! ;-) Is it just me or do kids scream more than they ever used to? Or rather kids are allowed to scream more than they ever used to be!

in the neonatal environment all noise needs to be managed and monitored Bliss Charter Standard 1.6 http://www.bliss.org.uk/...02/Baby_Charter_2011.pdf An older but relevant article (with particular reference to babies in incubators) http://adc.bmj.com/content/62/10/987.full.pdf The Neonatal unit use this products to monitor http://www.noisemeters.c...ct/soundear/neonatal.asp Their information leaflet states: Hearing impairment as a result of exposure to high noise levels can be expected but research over the last few years has also shown a link with language development. This seems to be related to the fact that a baby that goes full term is only exposed to lower frequency noise (< 250 Hz) during the brain and sensory development stages. babies are not to be exposed to higher noise levels for sustained periods Hope this is of use, oh the limit is 45dbs try and keep an area at this level --Good Luck when a baby crys at 110
