Precision Acoustics is a leading global supplier of hydrophones, transducers, acoustic materials and scanning systems for ultrasonic frequencies.Hydrophones are pressure measurement devices designed for underwater use. Variations in pressure, such as those induced by sound - or ultrasound - can be detected by the hydrophone, thus hydrophones are used for precise measurement of ultrasound fields. Precision Acoustics manufactures a variety of designs of hydrophone which lend themselves to measurement of all sorts of applications.This project looks at innovative ways of reconciling and understanding differences between hydrophone calibration regimes for the needle hydrophones in the crossover frequency region of 100--400 kHz, which has applications both in, for example, therapeutic medical or sonar/underwater areas. Modifications to the internal structure of the hydrophone will be modelled and measured. The restrictions due to the calibration regimes themselves routinely used in the underwater acoustics (kHz) and medical ultrasound (MHz) areas will be combinedly addressed by the application of acoustic fields generated using parametric arrays.

Precision Acoustics是用于超声频率的言语，传感器，声学材料和扫描系统的全球领先供应商。氢载体是设计用于水下使用的压力测量设备。压力的变化，例如声音或超声引起的压力变化，可以通过水音器检测到，因此氢气用于精确测量超声场。 Precision Acoustics manufactures a variety of designs of hydrophone which lend themselves to measurement of all sorts of applications.This project looks at innovative ways of reconciling and understanding differences between hydrophone calibration regimes for the needle hydrophones in the crossover frequency region of 100--400 kHz, which has applications both in, for example, therapeutic medical or sonar/underwater areas.将对水文的内部结构进行修改和测量。由于使用参数阵列生成的声道，将合并由于水下声学（KHz）和医疗超声（MHz）区域通常使用的校准机构本身的限制。
