The purpose of incubators is to allow the premature new-born to comple
te his development as like in his mother's uterus. As a risult the acu
stic environment in the incubator shuld be particulary reassuring and
stimulating for this young patient in order to incentivate his cogniti
ve learning. Considering the effects of noises on the babies' neuro-ps
ycological development, also considering that auditory system is perfe
ctly working since the 25th week of pregnancy, the autors asserted the
necessity of controlling the degrees and the quality of the noises in
side the incubators available in commerce. The results of such control
s reveal that incubators are inadeguate, so the autors suggest some te
chnical solutions to gain a substantial reduction of the noises inside
the incubators.
