新生儿听力的研究,国内外报导极罕。本文研制的简易便携型新生儿测听器有其普及实用的最大特点。为噪音发生器,能发出75、85、100dB三级强度的声信号,系由集成电路安装,用12V电池,附2s和20s定时开关,音频为250Hz、500Hz、1.5 kHz和3.5 kHz,50cm声场,声强保持不变,可用于新生儿生活的任何地方检测听力。对研究听力发育时间和早期发现耳聋以及优生、育婴都有重要意义。
Neonatal hearing research, extremely rare at home and abroad. This article developed a simple portable neonatal hearing aids have its most popular and practical features. Is a noise generator that emits three levels of 75,85,100dB acoustical signal, which is mounted by an integrated circuit with a 12-volt battery with 2s and 20s timed switches for audio at 250Hz, 500Hz, 1.5kHz and 3.5kHz, 50cm sound field , The sound intensity remains unchanged, can be used to detect hearing anywhere in newborns. The study of hearing development time and early detection of deafness and eugenics, infants and young children are of great significance.
