INCUBATOR WITH A NOISE MUFFLING MECHANISM AND METHOD THEREOF

摘要

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, (AmpRQVΔt) 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 AmpRQVΔt 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.

1. A noise-attenuating neonate incubator (NANI) comprising sound attenuating module (SAM) configured to decrease the sound amplitude ratio at time, ti, (AmpRatti) to a critical amplitude ratio value of the sound measured over a predetermined time, Δt, (AmpRQVΔt) or less, wherein said sound attenuating module (SAM) comprises:
a. at least one sound sensor in communication with a computer readable medium (CRM), configured for continuously sampling said sound amplitude ratio at time ti (AmpRatti) within said incubator; b. at least one CRM for storing said critical amplitude ratio value of said sound measured over a predetermined time, Δt, (AmpRQVΔt) and, said sound amplitude ratio at time, ti (AmpRatti); and, c. at least one sound attenuator in communication with said CRM for decreasing said sound amplitude ratio at time, ti; wherein a plurality of said sound sensors providing feedback signals at time ti to said CRM (AmpRatti); said CRM configured to instruct said sound attenuator, if AmpRatti>AmpRQVΔt, to operate such that AmpRatti
