Sound power radiation of dipole and bipole sources

AI Thread Summary
The discussion centers on the sound power radiation of two monopole sources operating at the same frequency, questioning whether in-phase or out-of-phase configurations yield greater far-field sound power. Participants clarify that the context involves small loudspeakers emitting low frequencies with omnidirectional radiation patterns. The relationship between the radiated sound power and the electrical power supplied to the sources is also examined. The conversation highlights the importance of understanding radiation patterns in determining sound power output. Overall, the focus remains on the effects of phase alignment on sound radiation efficiency.

Homework Statement


For a fixed given electrical power to two monopole sources, producing the same frequency. Which mode, either in-phase or out of phase, will radiate the most sound power into the far-field?

Homework Equations


Is the radiated sound power dependant of the given electrical power? Or is the radiated sound power dependant on the different radiation patterns of the sources (i.e. figure of 8 for a dipole)?

The Attempt at a Solution

sound power ?

dipoles and monopoles are for RF transmission
please clarify

Apologies. I should have been more specific. Assume the sources are two small loudspeakers radiating low frequencies, ie omnidirectional radiation.
 
No one?

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Egg Drop Challenge! Need ideas for winning designs'

I was thinking using 2 purple mattress samples, and taping them together, I do want other ideas though, the main guidelines are; Must have a volume LESS than 1600 cubic centimeters, and CAN'T exceed 25 cm in ANY direction. Must be LESS than 1 kg. NO parachutes. NO glue or Tape can touch the egg. MUST be able to take egg out in less than 1 minute. Grade A large eggs will be used.
