Ultrasound is sound that has a frequency above the audible range of man that is greater than 20 kHz.

超声是一种声波，在医学影象中，超声仪使用2MHz-10MHz间的声波，此一频率已远远超过人耳所能听到的20kHz。

The way the transmitter audio response is measured is to apply a fixed modulating signal level which produces 60% of rated system deviation (3 kHz in our case) at 1000 Hz.

要测量发射音频的频率响应，方法是加上一个固定调制信号电平，这个电平在1000HZ下产生系统设计频偏的60%（这里是3KHZ）。

Methods 16 patients who were diagnosed as myasthenia gravis with initial head and neck symptoms were determined by a pure tone audiometer and acoustic immitance measurement and then the acoustic reflex was reexamined 30 min after injection of Neostigminum sulfate 0.5～1?

对以头颈部和五官症状为首发症状而到我科初诊的16例重症肌无力患者进行纯音测听和声导抗检测，并在肌肉注射甲基硫酸新斯的明0.5～1.0？mg，30？min后复查声反射。检测用0.5、1.0、2.0和4.0？kHz的纯音作同侧和对侧刺激，比较用药前后有无声反射及其阈值、振幅变化、有无衰减等。

Methods Pure tone audiometry,SISI,ABLB and white-noise masking effect(Langenbeck's methods) audiometries were performed in 30 patients (44 ears) with sensorineural hearing loss with BOSCH audiometer made in Germany.

用德国产BOSCH听力计对30例(44耳)感音神经性听力损失患者作纯音测试和阈上测听(包括Langenbeck，SISI和ABLB试验)，比较三种试验相对于三种听力曲线及1，2和4 kHz三频率的阳性结果。

Methods: Thirty children with normal hearing had the ASSR and pure tone audiometry determined at 0.25, 0.5, 1, 2, 4 and 8 kHz.

对30例（60耳）正常5～10岁儿童分别行ASSR与纯音测听测试。

In today's technology, the data rate for typical DLC systems operating in the 5 to 20 kHz range is 300 baud or less.

在今天的技术，其数据传输率为典型的类金刚石系统运行于5日至20千赫的射程也就是300波特或更少。

Better yet, over the critical midrange between 250 Hz and 2.5 kHz the variation was only +/-2 dB, which would be a remarkable achievement for even a considerably more expensive speaker.

在250到2.5kHZ 的中频测试中，它的偏离度只有＋/－2DB ，通常只有价格极为昂贵的天价音箱才具有这类技术优势。。。。

Resonance in the region of +40 to +150 KHZ for plano parallel resonators biconvex or piano-convex resonators.

在AT切型中，对于平面芯片，"不和谐的响应"只存在于主响应的+40至+150KHZ之间，对于平凸或双面凸的芯片，寄生则在+200至+400KHZ之间。

And of course all this can be done at any bit depth and sample rate up to 24-bit, 192kHz, and be fully automated via MIDI and your host sequencer!
