Where noise is continuous, the equivalent sound pressure level should not exceed 30 dBA indoors, if negative effects on sleep are to be avoided. When the noise is composed of a large proportion of low-frequency sounds a still lower guideline value is recommended, because low-frequency noise (e.g. from ventilation systems) can disturb rest and sleep even at low sound pressure levels. It should be noted that the adverse effect of noise partly depends on the nature of the source. A special situation is for newborns in incubators, for which the noise can cause sleep disturbance and other health effects. aunque no se hasta donde puede decirme mi movil la verdad de los decibelios, que me marca 38 con ventana cerrada, si es verdad que es molesto, y retumba en el piso. no sé cómo lo hará ella abajo
