During a few trials (n = 3), the acoustic output
was broadcast at a maximum sound pressure level of 73 to 75 dB at a distance of 3 cm from the speaker; these intensities coincided with the upper limit of the normal range of mantid-generated sounds at the same distance away from the sound source.

from Diagnostic Ultrasound Equipment", IEEE Transactions on Ultrasonic Ferroelectrics and Frequency Control, Vol.
Bragging rights go to the company with the latest in a series of firsts--first to market, first with the current top in areal density, first with a new low in acoustic output
, and even first with proprietary drive diagnostics can earn a competitive advantage, all other things being equal.
The signal generator with PVDF requires more power than that with ceramic materials to generate the same acoustic output
The system's electronics are integral to the listening experience and include a new amplifier that is substantially smaller, lighter and more energy-efficient than conventional amplifiers, with no sacrifice in acoustic output
In very general terms, training the amplified singer focuses on a large inventory of predictable and controllable sounds at relatively low acoustic power, while training the unamplified singer focuses on the few combinations that maximize acoustic output
Also featured will be the handheld HS-Micro packs a peak acoustic output
of 141 dB to penetrate high background noise and to reach an intended target at 500 m.
Wayne Moore, Acertara's President and CEO, added, "The world-wide regulatory requirements for ultrasound systems and probes related to acoustic output
power, thermal dosing, and other complex acoustic performance parameters continues to grow in both scope and complexity.
This research study monitors the effects of epigastric activity on both respiratory and acoustic output
in the singing voice.
