5-9 Acoustic Impedance

results in a greater volume velocity. Specific acoustic impedance (z) is point impedance, that is, the impedance that indicates the pressurevelocity relationship at one specific point in unbound space. In contrast, acoustic impedance (Z) is the ratio of the averaged sound pressure across a FAQs Subsea Thickness Thickness Gauges Cygnus Yes. Although the majority of applications require the gauges to be used on steel, the gauges can be used on a variety of other materials by either entering the known velocity of sound into the gauge in metres per second, or by calibrating the gauge with a known thickness of the material under test.

Re:velocity of sound in steel contaning 14% magamese

Jul 17, 2012 · Re:velocity of sound in steel contaning 14% magamese. auto calibration on most equipment will give you velocity. otherwise calibrate your machine in a material with known velocity note down the time base line and go to the unknown velocity and note the echo time on the time base line and relate it mathematically.

Sound can travel great distances in many solid materials, and moreover, it travels quickly. The speed of sound in an iron rail is roughly ten times that in air! In this experiment we measure the speed of sound in a plastic rod. The technique we use is straightforward.
