|
What instrument measures acoustic pressure at specific locations within the sound beam?
|
Hydrophone
Microprobe |
|
|
What instrument is made of a small hypodermic needle with a tiny piece of PZT at its tip; attached to an oscilloscope at the other end
|
Hydrophone
Microprobe |
|
|
A hydrophone measures what three variables?
|
Period
PRP PRF |
|
|
This instrument allows us to view the shape of a sound beam in a medium; it is based on acousto-optics or the interaction of sound and light
|
Schlieren
|
|
|
This instrument measures the total power in a sound beam through the process of absorption; power is calculated by measuring the temperature rise and the time of heating
|
Calorimeter
|
|
|
This instrument measures the sound beam's power at particular locations in the beam
|
Thermocouple
|
|
|
What is the difference between a calorimeter and a thermocouple?
|
A thermocouple measures power at particular locations in the beam
A calorimeter measures power of the entire beam |
|
|
This instrument changes color with temperature
|
Liquid Crystals
|
|
|
What is it called when a beam's small but measurable force is absorbed by or reflected by the target, the target acts as an extremely sensitive postal scale
|
Radiation Force
