Sound power radiation of dipole and bipole sources

Click For Summary

Homework Help Overview

The discussion revolves around the sound power radiation of two monopole sources operating at the same frequency, specifically examining the effects of their phase relationship (in-phase vs. out of phase) on far-field sound power radiation. The context includes considerations of radiation patterns and their implications for sound power output.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants are questioning the dependency of radiated sound power on electrical power versus the radiation patterns of the sources. There is a focus on clarifying the nature of the sources, with an initial misunderstanding regarding the type of sources being discussed.

Discussion Status

The discussion is in an early stage, with some participants seeking clarification on the specifics of the sources involved. There is a lack of responses to the original question, indicating that the topic may need further exploration or rephrasing for better understanding.

Contextual Notes

There is a mention of the sources being small loudspeakers radiating low frequencies, which may influence the assumptions about their radiation characteristics. The initial confusion regarding monopoles and dipoles in the context of RF transmission suggests a need for clearer definitions in the discussion.

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 dependent of the given electrical power? Or is the radiated sound power dependent 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?
