blog of acoustics, noise, vibration & audio-visual systems
In this TED Conference video, David Byrne, lead singer of Talking Heads, gives us a brief a history of music and how it evolved in relation to architectural acoustics and reverberation. Worth the watch.
One issue this video doesn’t address is that architectural acoustics can be designed and optimized in any building. Sure, Carnegie Hall has a signature sound, but that sound can be altered. He mentions in the video that arenas are notorious for terrible acoustics. Again it doesn’t have to be that way. At Acoustics By Design, we engineer acoustical solutions for everything from nightclubs to theaters to outdoor amphitheaters. With the right tools, experience, and expertise, we can design the acoustical performance for your next performance space.
We all have seen nice big projector screens that have an image that is just too dim to be clearly seen. To protect against this occurrence, we set a target brightness level during the design process, and we base it on a number of variables. The physical screen size needs to be compared to the amount of light from the projector. This comparison will give us lumens per square foot of screen. The lumens per foot result is compared with a target to determine if the projector is bright enough or even too bright. But how do we determine the target? (more)
