If this surprises you, consider a domestic stereo system-typical electrical output 50 W RMS per channel, Loudspeaker efficiency 3 %, music mean to peak ratio 0.1, mean acoustic power output 150 milliwatt.

Speaker efficiency is a metric that only measures the actual percentage of electrical power that the speaker converts to acoustic power and is sometimes a more appropriate metric to use when investigating ways to achieve a given acoustic power from a speaker.

The band had previously garnered attention for covering well-known rock songs in an " acoustic power trio " style, but " Suspicious Activity ? " includes only one cover version : the theme to the 1981 movie " Chariots of Fire ".

According to Sakaki, Minamoto had been charged the administration of Caroline's rehabilitation after the experiment results in the childish personality Carrie that has very potent psychokinetic and acoustic powers but not the maturity for their prudent use ( much like was the case with Kaoru ).

Overall, the album was general rock, but also featured several acoustic power ballads, such as " You're the One I Love ", " California Girl ", " Bullets from a Gun ", " Make Me ", and " Mexican Sky ".

Although the CEN / TC 113 Business Plan outset was that " consumers increasingly require a low acoustic power of these units as the users and their neighbours now reject noisy installations ", no standards for noise barriers or other means of noise protection had been developed by January 2016.

When RASS is added to a radar profiler, three or four vertically pointing acoustic sources ( equivalent to high quality stereo loud speakers ) are placed around the radar wind profiler's antenna, and electronic subsystems are added that include the acoustic power amplifier and the signal generating circuit boards.

The acoustic power ( energy per second ) crossing unit area is known as the intensity of the wave and for a plane wave the average intensity is given by I = q ^ 2 / ( \ rho c ) \,, where q \, is the root mean square acoustic pressure.

Thus, a 100 W driver ( " A " ) rated at 92 dB for 1 W @ 1 m sensitivity puts out twice as much acoustic power as a 200 W driver ( " B " ) rated at 89 dB for 1 W @ 1 m when both are driven with 100 W of input power.
