Studio Monitoring Design (Hardcover)
by PHILIP NEWELL

http://www.amazon.com/gp/product/024...lance&n=283155




I found this 1997 book on high level monitoring and studio control room design very interesting. Detailed discussions of what the folks who make the records are listening to.

Review
'...an intense trip, spinning through loudspeaker-based audio, swathes of which the enthusiast will want to read many times... This is one of the most important 'real world' books to be published about speakers and acoustics, sewing together measurement and listeneing. It should certainly be compulsory reading for anyone who designs loudspeakers or amplifiers!'
Ben Duncan, Hi-Fi News, 1997

what i gathered in the past month from my quest to biuld the perfect midbass horn for my 2226J's.

by John Eargle.

Embarrassingly, while we have included many of John Eargle's writings, I find we are missing much of his ground breaking work.

This is a pic of the cover of Don's copy...

I have spent hours staring at that photo, and pondering the thought/planning/knowledge that went into the flown layout, "way back then".
- Note how the L/R stacks have the horns staggered - never adjacent
- Note how the center cluster is stacked - horns top and bottom, and arrayed to disperse their dispersion pattern...

Genius.

Comb filtering effects ruin the sound reproduction of an othewise great system. Never forget...

. Thank you Ruediger!

I read this many years ago and recently my interest in the apparent apex phenomenon was rekindled and I could not for the life of me remember enough about this paper to find it.

There is one definition in there that my years had fuzzied. You would think if not Altec, at least I would have remembered Ted Uzzle coauthored.

Safely stored now thank you!

All the best,
Barry.

This 416 page paperback, published 2009 by Granta Publications, London appears to be the best contemporary explanation of how recorded music evolved in the last 50 years. Book does not hold back on presenting views that may offend many in the Audio Engineering industry. Despite the best intentions, it infers greed was the primary driver of evolution and created a long-term decline in quality. Has many fascinating insights to the creation of new products and issues like remastering, loudness levels, optimal S/N, single microphone vs multi-track, etc. The book ends about 2008.

2 of the best resources on web about the tapped horn...the wave of the future....kicking everyone's arses (esp JBL since they just bout stopped producing bass horns)

The genius....he use to work for Nasa to simulate/measure sonic booms...invented the servo drive and Lab horn and now is destroying the competitors with his new line of Danley subs....

http://www.danleysoundlabs.com/

im tryn to come up (with a lot of help) of a tapped horn design for jbl subs.

Crispin Pritchard just posted this over on Pro Sound Web. Seems like a useful resource. I thought it might be of interest here, too, to all y'all...

I think that interested parties might find some useful info at my web site www.gedlee.com. While I do sell products, there is still a lot of useful information posted. I'm trying not to be commercial here, but I do think that a glance might prove interesting since none of it is referenced here.

I'll understand if this post does not survive.

Title: Introduction to Electro-acoustics and Audio Amplifier Design
Author: W. Marshall Leach, Jr.
URL: http://users.ece.gatech.edu/~mleach/
Publication: Kendall/Hunt Publishing Co., 2001, ISBN 0-7872-7861-0, Second Edition, Revised Printing

URL: http://www.kendallhunt.com/cgi-bin/p...arch_str=leach
Abstract: This book is an outgrowth of a senior level elective course in audio engineering that the author has taught to electrical engineering students at the Georgia Institute of Technology. The first part of the book covers basic acoustics as it pertains to the field of audio engineering. Remaining chapters, address the application of the tools of electro-acoustics, to the design of loudspeakers, their enclosures, crossovers, networks, acoustic horns, and audio amplifiers.

Title: Acoustics
Author: Leo L. Beranek
Publication: ASA-B, 491 pages, Hardcover, 1986, (originally published 1954).
URL: http://asa.aip.org/publications.html#pub04
Abstract: An indispensable source of practical acoustical concepts and theory, with information on microphones, loudspeakers and speaker enclosures, room acoustics, and acoustical applications of electro-mechanical circuit theory.

Title: Vibration and Sound
Publication: ASA-B, 468 pages, hardcover, 1981, (originally published 1936)
URL: http://asa.aip.org/publications.html#pub22
Author: Philip M. Morse
Abstract: This publication provides students and professionals with the broad spectrum of acoustics theory, including wave motion, radiation problems, the propagation of sound waves, and transient phenomena.

Title: Acoustical Engineering
Publication: D. Van Nostrand Co., Inc. (1957)
Publication: Professional Audio Journals, Inc. (1991)
URL: http://www.audioxpress.com/bksprods/books/bkpa1.htm
Author: Harry F. Olson
Abstract: Comprehensive but dated text on the subject of acoustical engineering. Its reprinting at this late date says volumes about the value and significance of Olsen’s work. For those involved in this discipline, a copy of this book should be considered a necessary addition to their reference library.

Reference for Musicians

Title: The Physics of Musical Instruments
Author: Neville H. Fletcher
Author: Thomas D. Rossing
Publication: Springer-Verlag, 1998, ISBN 0-387-98374-0, Second Edition
URL: http://www.springeronline.com/sgw/cd...ngeHeader=true
Abstract: While the history of musical instruments is nearly as old as civilization itself, the science of acoustics is quite recent. By understanding the physical basis of how instruments are used to make music, one hopes ultimately to be able to give physical criteria to distinguish a fine instrument from a mediocre one. As yet, many of the subtleties in musical sounds of which instrument makers and musicians are aware remain beyond the reach of modern acoustic measurements. This book describes the results of such acoustical investigations - fascinating intellectual and practical exercises. Addressed to readers with a reasonable grasp of physics who are not put off by a little mathematics, this book discusses most of the traditional instruments currently in use in Western music. A guide for all who have an interest in music and how it is produced, as well as serving as a comprehensive reference for those undertaking research in the field.

It's far past time for re-igniting this thread. We have many new members who've surely got some gems to add.

A must read, in my opinion, is

Handbook for Sound Engineers, Third Edition, Glen M Ballou, ed.
Focal Press

Here's the Amazon Link: http://www.amazon.com/gp/product/024...books&n=283155

There is a paperback for fewer pesos...

In another thread I posted a link that I think everyone here will find extremely useful:
http://www.vibrationdata.com/piano.htm

I suggest that you also look at the rest of the site, as there is some very useful and cool info on acoustics and stuff...."stuff" is the technical nomenclature.

I hope you find it as fascinating as I have....and bookmark it.
