A noise-attenuating neonate incubator (NANI) comprising sound attenuating module (SAM) configured to decrease the ratio, (AmpRatt_i), of the sound's amplitude at a time, t_i, to a reference amplitude, to a critical amplitude ratio value of said sound measured over a predetermined time, At, (AmpRQV&Dgr;t) or less. The SAM comprises passive noise attenuating, active noise attenuating or both. A method for sound attenuating a neonate incubator, characterized by: (a) obtaining a noise-attenuating neonate incubator (NANI) comprising sound attenuating module (SAM) configured to decrease AmpRatt_i to AmpRQV&Dgr;t or less; (b) accommodating said neonate in said NANI; and, (c) attenuating said noise by said at least one SAM, thereby changing the sound signature. |
