What it is The Electronic Systems Professional Alliance (ESPA) exists to maintain and develop an entry-level certification program for low voltage Electronic Systems Technicians (ESTs). The curriculum covers five key areas: Electrical basics Tools Construction methods and materials Wiring and installation practices Standards, codes, and safety practices Participants must pass an independently proctored test […]
Horizontal Viewing Angles The horizontal viewing angle is the angle subtended by a straight line from each side of the screen to the seating position. The main two standards in the commercial world are the SMPTE and THX specifications as summarized in the diagram below: New cinemas built to THX specifications have a minimum viewing […]
What is ‘THX Reference Level’? Reference level is a calibrated volume setting used for both movie production (in dubbing stages and post production houses) and reproduction (in screening rooms and theaters). The human hearing system is non-linear, especially in the bass, so having a consistent playback level – a reference – is critical if the […]
“When it comes to high-performance, high-value power amplifiers, few do it better than Parasound.”— Andrew Robinson, Home Theater Review Why do we use Parasound Amplifiers? Superb sound quality thanks to the design skills of the legendary audio designer John Curl and the use of balanced, high bias class A/AB topologies. There have been a […]
“The true sign of intelligence is not knowledge but imagination.”— Albert Einstein We at Acoustic Frontiers do not stop at “the basic” industry certifications and qualifications. In acoustics in particular we continue to drive industry thought leadership as demonstrated by the articles and white papers we publish. Acoustical Measurement Standards for Stereo Listening Rooms […]
Ahhh….the home theater pre-pro….my thoughts on them are basically
summarized by the phase “can’t live with them, can’t live without them”!
Modern pre-pros are the brain of all modern home theaters. An AVR
(audio video receiver) is essentially a pre-pro and multi-channel power
amplifier in one box. Pre-pro’s do a number of essential things without
which it would be virtually impossible to watch movies in surround
It’s been quite a while since the last blog update on the Acoustic Frontiers Demo Room. However I am happy to say that there has been a lot of progress, although the room is still not finished! The room is already ‘up and running’ in the sense that it can be used for music and movies but there are still some areas we are working on and a couple of key items that still need to be installed. Today I am going to give a update on the interior decoration and fit out of the room.
It’s been just over a year since the UK’s National Physical Laboratory first released information on their innovative laser-based acoustical mapping technique. Thanks to UK loudspeaker company PMC we now have a real life use case for this technology – using lasers to study the dispersion characteristics of loudspeakers. All speakers have off axis frequency […]
Introduction This main focus of this blog article is to show you how easy it is to EQ your room or sub using parametric EQ. First we look briefly at the typical bass issues in our listening rooms and home theaters and reveal the Acoustic Frontiers targets for good bass. Next we discuss some common […]
Setting the Stage for Battle! Earlier this year Acoustic Frontiers had the opportunity to improve a two channel and home theater system in Tucson, Arizona. Our client owned a Polk / Onkyo system which incorporated the latest Audyssey XT32 ‘room correction’ algorithms. However he was unhappy with overall sound quality and wanted to know how […]
