Power Measurements


An acoustic wave transfers energy as it propagates. This is the power of the beam.
It is measured in Watts and provided the whole of the acoustic beam is included
in the measurement it is not dependent on position.

Precision Acoustics manufactures Radiation Force Balances and Check Sources
which can be used to measure ultrasound power according to the IEC Standard
61161. All products are supplied with a calibration from The National Physical
Laboratory, LONDON
