So while threshold levels of for the microwave audio effect of 267mW/cm² for 1.3GHz and 5000mW/cm² 2.9GHz, respectively, were reported by Frey in 1961, for the peak amplitude (providing the pops) and would only give an average (sustained) power density of only 0.4mW/cm² and 2mW/cm² respectively [7] similar to current cellphones.
Flip cameras' video quality was unusually good for their prices and sizes. [8] They can record videos at different resolutions. FlipHD camcorders digitally record high-definition video at 1280 x 720 resolution using H.264 video compression, Advanced Audio Coding (AAC) audio compression and the MP4 file format, while the older models used a 640 x 480 resolution.

The experiment also supported that in-ear headphones worked better at reducing noise than outer-ear headphones. [3] Cancellation focuses on constant droning sounds like road noise and is less effective on short/sharp sounds like voices or breaking glass. It also is ineffective in eliminating higher frequency noises like the sound of spraying.
In the video, Torres said repeatedly that he couldn't breathe, and Boone can be heard laughing. "That's what you do when you choke me," Boone responded, what prosecutors called taunting .
