This Is a Serious Set of Speakers |
This Is a Serious Set of SpeakersThink your Yamaha or Bose speakers put out the power? Well, Wyle Laboratories has a 165 dB speaker, the WAS3000, that will melt you ear wax - literally. For comparison, a food blender is about 9 dB. A 747 jet spooled up for takeoff is 130 dB. The Space Shuttle generates 150 dB. The threshold of pain for most people is around 125 dB. 150 dB can stop your heart. This technology is being explored to use in Active Noise Cancellation for around airports, where these speakers would generate sound 180° out-of-phase with aircraft noise to help dampen the level in surrounding areas. A huge collection of my 'Factoids' can be accessed from my 'Kirt's Cogitations' table of contents. Topical Smorgasbord, another manifestation of Factoids, are be found on these pages: | 1

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ... All trademarks, copyrights, patents, and other rights of ownership to images and text used on the RF Cafe website are hereby acknowledged. My Hobby Website: AirplanesAndRockets.com
