HI all!

This is the scenerio. We have a conference room (14' x 10') with no real walls; the partitions are made of fabric. This room sits about 10 people.

Without building "real" walls, we need to make audio from a TV display not so audible to the others around. I was looking at a few dome speaker solutions and wireless headsets. Just wondering if anyone has any ideas or recommendations.


Best,

T

For a speaker to have 180 degree dispersion the baffle must be a full wavelength in dimension. At 1kHz that's not difficult, being 1.1 feet, but at 100Hz it's 11.3 feet. Headphones is the only real solution.

Brown Innovations has developed some amazing directional audio solutions. Both dome and non-dome directional speakers that can keep sound contained to different sized areas. Blog page details some high profile installations http://browninnovations.wordpress.com/

One is a line array, highly directional on the long axis as that axis is over a wavelength long in the pass band, the other a parabolic reflector. I doubt either is cost effective for the OPs situation.

Bill did you read all the entries in blog post? Way more than just two speakers. Additionally, Brown's domes are not parabolas, they are hemispheres. All parabolas do is reflect audio back down to the floor. Hemispheres actually focus stereo audio to the right and left ear of the listener. They far more effective at focusing audio than cheap parabolas. I would be happy to provide you with additional details if you have an interest in learning more about focused audio.

yes go with headphones.

headphones are unsanitary especially if they are going to be shared by different listeners. directional speakers will work perfectly for the application.
