The combination of these three types of modes form a dense set of possible standing wave frequencies in the room, and if any of the home cinema's dimensions are integer multiples of ... http://www.vipcinemas.co.uk/articles/modal-distribution-in-dedicated-home-cinemas-1417.html Another aspect of reverberation which caught home cinema designers by surprise is an observation. The observation is that, as well as suffering many reflections, the sound energy in a home cinema's reverberant decay will have travelled through a lot of air. In fact the distance that the sound will have ... http://www.vipcinemas.co.uk/articles/the-effect-of-air-absorption-in-home-cinema-design-1413.html A factor which has been found to be important for the listener is the presence of dense diffuse reflections from the side walls in a home cinema room, called lateral reflections. The effect of these is to envelop or bathe the listener in sound and this has been found to be necessary, ... http://www.vipcinemas.co.uk/articles/lateral-reflections-in-home-cinemas-1406.html The Escient FP-1 iPod docking station provides all the functionality and management features that you should expect from a Fireball.

An iPod can now become a music server that distributes all audio content ... http://www.vipcinemas.co.uk/articles/escient-fp-1-ipod-dock-1397.html It has already been discussed that in home cinema installations the measure of reverberation time is actually the time it takes the sound to fall by 60 dB. This is not particularly relevant psychoacoustically, and it is also very difficult to measure in situ. This is due to the presence of ... http://www.vipcinemas.co.uk/articles/home-cinema-design-early-decay-time-1394.html By simply looking at Sabine's equation, one can clearly see that the reverberation time of home cinema installations depends on the volume, surface area and the average absorption coefficient in the room. However, the absorption coefficients of any acoustic wall panels are not constant with frequency. This means that, assuming ... http://www.vipcinemas.co.uk/articles/reverberation-time-variation-with-frequency-1385.html Today's multi room audio installations require multiple sources to be distributed throughout the home. The biggest challenge with audio distribution is to be able to digitally store all content, in order to allow easy access from every room. Escient music servers are the pinnacle of digital media management systems. There are two ... http://www.vipcinemas.co.uk/articles/escient-se-500i-music-server-1378.html Quite often we come across home cinema installations where too many acoustic panels are being used. The very short reverberation times that occur pose an interesting problem. One of the assumptions behind the derivation of the reverberation time calculation of dedicated home cinemas was that the sound energy visited all the ... http://www.vipcinemas.co.uk/articles/dedicated-home-cinemas-with-short-reverberation-times-1373.html XP-8.4 is Elan's latest touch panel, offering a large 8.4" display for an exciting control experience. Elan's large touch screen is a unique combination of wireless technology and systems integration for today's demanding home automation projects.
