In any event, Qantas apparently reached a confidential settlement with the woman. </p> <p>I’ve had to fly with temperamental children, but luckily I’ve never had anything that bad happen to me - and if it did, hopefully my <a href="http://www.amazon.com/gp/product/B000BQSGMM?ie=UTF8&tag=crossspectrum-20&linkCode=as2&camp=1789&creative=9325&creativeASIN=B000BQSGMM">ER6i’s</a><img src="http://www.assoc-amazon.com/e/ir?t=crossspectrum-20&l=as2&o=1&a=B000BQSGMM" width="1" height="1" border="0" alt="" style="border:none !important; margin:0px !important;" /> would shield me from the brunt of it.</p> <hr/> Audio books, home theater components, DVD's and more at the <a href="http://www.cross-spectrum.com/store">Cross-Spectrum Store</a><br> Tue, 27 Jul 2010 01:30:00 GMT http://www.cross-spectrum.com/weblog/2010/07/27#Jul1227010_1 Herb Singleton blog@cross-spectrum.com HDMI Killer? http://www.cross-spectrum.com/weblog/2010/07/12#Jul122010_1 <p>Introducing <a href="http://www.hdbaset.org/">HDBaseT</a>: <ul> <li class="normal">Inexpensive, widely available CAT 5/5e/6 networking cable</li> <li class="normal">Standard RJ-45 connector</li> <li class="normal">Long cable lengths</li> <li class="normal">Field terminable</li> <li class="normal">Up to 100 watts of power (!)</li> <li class="normal">HD video</li> <li class="normal">High-def multi-channel lossless-audio capable</li> <li class="normal">High-speed ethernet networking</li> </ul> </p> <p>I think I join the rest of the <a href="http://www.audioholics.com/news/industry-news/hdmi-dead-hdbaset">audio community</a> in praying to $deity for a quick death to HDMI. </p> <hr/> Audio books, home theater components, DVD's and more at the <a href="http://www.cross-spectrum.com/store">Cross-Spectrum Store</a><br> Mon, 12 Jul 2010 00:15:00 GMT http://www.cross-spectrum.com/weblog/2010/07/12#Jul122010_1 Herb Singleton blog@cross-spectrum.com The TenderNoise Project http://www.cross-spectrum.com/weblog/2010/06/17#Jun172010_1 <p><a href="http://www.movity.com/">Movity</a> is a Bay Area startup with a goal of making it easier for people to move by identifying compatible neighborhood characteristics so prospective renters and buyers know “what it is REALLY like to live there.” One of the characteristics they have identified as being important to buyers and renters is noise. To that end, they’ve produced the <a href="http://tendernoise.movity.com/">TenderNoise Project</a>, a demo that shows measured noise levels in and around San Francisco’s <a href="http://en.wikipedia.org/wiki/Tenderloin,_San_Francisco">Tenderloin</a> neighborhood. </p> <p> The data <a href="http://blog.movity.com/post/702213904/the-visualization-of-noise">were collected</a> using <a href="http://www.testequipmentdepot.com/reed/rh-data-loggers/st173.htm">Reed ST-173</a> logging meters (also sold as the <a href="http://www.metershack.com/metershack-high-accuracy-digital-sound-noise-level-data-logger-datalogger-with-usb-interface.html">CEM DT-173</a>) deployed at various intersections in the neighborhood. The levels are high, but they are consistent with what I remember measuring in and around downtown San Francisco. </p> <hr/> Audio books, home theater components, DVD's and more at the <a href="http://www.cross-spectrum.com/store">Cross-Spectrum Store</a><br> Thu, 17 Jun 2010 00:38:00 GMT http://www.cross-spectrum.com/weblog/2010/06/17#Jun172010_1 Herb Singleton blog@cross-spectrum.com Nissan LEAF sound http://www.cross-spectrum.com/weblog/2010/06/14#Jun142010_1 <p>Via the <a href="http://nissan-leaf.net/2010/06/11/nissan-leaf-sound-revealed/">Nissan LEAF blog</a> - Nissan has unveiled the sound it’s Nissan LEAF electric car will make to warn pedestrians of its approach.

It’s fairly high frequency which will make it noticeable (and potentially more annoying at a given sound level) but on the other hand it should be easy to focus in the direction of travel and minimize wayside noise. I guess we’ll have to wait and see. </p> <hr/> Audio books, home theater components, DVD's and more at the <a href="http://www.cross-spectrum.com/store">Cross-Spectrum Store</a><br> Mon, 14 Jun 2010 01:21:00 GMT http://www.cross-spectrum.com/weblog/2010/06/14#Jun142010_1 Herb Singleton blog@cross-spectrum.com Before Radar http://www.cross-spectrum.com/weblog/2010/06/10#Jun102010_1 <p> Web Urbanist has depictions of the <a href="http://weburbanist.com/2009/12/27/sound-mirrors-before-radar-hearing-was-believing/">acoustic detection apparatus</a> used by armies to indentify enemy airplanes before the days of radar.</p> <hr/> Audio books, home theater components, DVD's and more at the <a href="http://www.cross-spectrum.com/store">Cross-Spectrum Store</a><br> Thu, 10 Jun 2010 01:18:00 GMT http://www.cross-spectrum.com/weblog/2010/06/10#Jun102010_1 Herb Singleton blog@cross-spectrum.com
