| Abstract |
This paper proposes to reduce the radiation of a sound source inside a cavity through the baffled opening by using an array of loudspeakers and microphones. The system is called a planar virtual sound barrier because it acts like a concrete sound barrier to block the transmission of sound but does not affect light and air circulation. An analytical model for the planar virtual sound barrier is developed based on the modal superposition method to calculate the sound field in and outside a rectangular cavity with a baffled opening. After the model is verified with numerical simulations, a performance study of the planar virtual sound barrier is carried out based on the proposed analytical model, and then the results are confirmed by experiments. The mechanisms of the planar virtual sound barrier are investigated and it is found that three mechanisms work together in the system, including changing the impedance of the primary source, modal control, and modal rearrangement. It is also found that there exist some frequencies where the sound cannot be controlled if all the secondary sources are on the same plane parallel to the opening, and the reasons behind the phenomenon are explained. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 07 November 2015.
All research outputs
#15,067,837
of 25,377,790 outputs
Outputs from Journal of the Acoustical Society of America
#7,435
of 10,577 outputs
Outputs of similar age
#143,824
of 297,297 outputs
Outputs of similar age from Journal of the Acoustical Society of America
#36
of 124 outputs
Altmetric has tracked 25,377,790 research outputs across all sources so far. This one is in the 40th percentile – i.e., 40% of other outputs scored the same or lower than it.
So far Altmetric has tracked 10,577 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.5. This one is in the 29th percentile – i.e., 29% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 297,297 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 51% of its contemporaries.
We're also able to compare this research output to 124 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 70% of its contemporaries.
