Friday, May 20, 2011How To Make High-Resolution Impedance Measurements
Pat Brown 05/20/11 07:31 AM, 0 CommentsBecause the impedance of a loudspeaker is a frequency-dependent parameter, it must be measured at multiple frequencies to get a true picture of what the amplifier is “seeing” at its output terminals. While very sophisticated methods and instruments exist, you can get a pretty good idea about the impedance curve of a loudspeaker with a standard real-time analyzer. You will need a pink noise generator and voltage source of at least 10 volts RMS to drive the loudspeaker. A small… View this post

Tuesday, May 17, 2011A Ghost Story: Low Frequency Illusions Created By Standing Waves?
05/17/11 08:40 AM, 0 CommentsBefore working at Coventry University in Coventry, UK, I designed anesthetic machines in a lab that was two garages end to end. The lab was long and thin, rather like a railway carriage. There was no hint of the strange events that would unfold. As I arrived one morning, I reached for the door handle and came face to face with the cleaning lady who was in a state of distress. She told me she had just been crept up… View this post

Method Not Madness: Correctly Troubleshooting Audio Interfaces
Bill Whitlock 05/16/11 08:13 AM, 0 CommentsPreviously (see here and here), we’ve looked at how unbalanced audio interfaces work, as well as how grounding-related noise can actually couple into the signal path. Of course, under fortuitous conditions, audio systems may be acceptably quiet in spite of poor techniques. But physics will ultimately rule and noises may later appear for no apparent reason – remember, noises that disappear by themselves also tend to re-appear by themselves! Most systems consist of more than two pieces of interconnected equipment,… View this post

Friday, May 13, 2011Dealing With Multi-Function Performance Rooms & Spaces
Paul Stark 05/13/11 08:42 AM, 0 CommentsEditor’s Note: This story was extracted from from RE/P, Vol 5, Number 1, which originally ran in Jan/Feb 1974. While somewhat dated in regard to specific technological advances, this text is still full of solid, relevant information. “Multi-Function” is a phrase we have invented to describe the spectrum of challenges, problems and responsibilities sound people are continually exposed to while working to achieve the best possible audio environment in club-type establishments. The obvious grammatical redundancy of the phrase is intended… View this post
