by Rane's engineer Dennis Bohn (2002). Great stuff on crossover theory, filter design and use, and balanced vs unbalanced with attention to ground loops.

Great stuff, although it does promote Rane gear. Regardless, they've done a good job...

...by John Eargle (1980, 2nd ed).

A wonderful compilation of techniques and experiences with recording that translate to reproduction knowledge.

http://www.amazon.com/exec/obidos/tg/detail/-/0442225571/qid=1083632827/sr=1-1/ref=sr_1_1__i1_xgl14/102-0254353-2260900?v=glance&s=books

Long out-of-print, but Amazon's affiliated used booksters are able to find good quality copies.

I've got a bunch of sound reference books but they're all now in boxes in the garage, suffering from my recent move, until I get bookshelves back up.

I can't remember the title or author offhand, but my favorite is a big yellow book about 3/4" thick - I've got it all marked up with pencil notes...

The New Audio Cyclopedia, Sound Engineers handbook. By Glenn Ballou. Last printing in the 90,s.

Alot of technical information of speakers, electronics, and acoustics. As well as recording, types of gear for different applications. Informative large hard cover book.

Although it is out of print you can try www.alibris.com. They specialize in hard to find and out of print literature.

URL: http://www.kendallhunt.com/cgi-bin/pubs.cmd?product=general&searchfor=author&search_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

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/cda/frontpage/0,10735,4-102-22-1520484-0,00.html?changeHeader=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.

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!'

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...

The ear is an extraordinary sensory organ. Two books to introduce how and why you hear:

The Physics and Psychophysics of Music: An Introduction (http://www.amazon.com/Physics-Psychophysics-Music-Introduction/dp/0387094709/ref=sr_1_1?ie=UTF8&s=books&qid=1254398412&sr=1-1) by Juan G. Roederer:
The 2nd edition has much (Year 12) physics and a little bit of anatomy. More into the accoustics than biology. Covers how sounds are generated and heard.

Bases of Hearing Science (http://www.amazon.com/Bases-Hearing-Science-John-Durrant/dp/0683027379/ref=sr_1_1?ie=UTF8&s=books&qid=1254398674&sr=1-1) by John D. Durrant and Jean H. Lovrinic (Paperback - Jan 15, 1995)
A lot of anatomy and a little bit of (Year 12) physics. The biology is thoroughly dissected into what happens to sound after it hits your ears. You will never stick anything in your earhole again once you realise how delicate it is on the other side.

Both books have absolutely nothing about loudspeakers.

Handbook For Sound Engineers 4th edition. The Acousic Measurement and Small Room Acoustic chapters are really good. 10-2008

Some of my favorites not yet listed.

Sound System Engineering by Don Davis and Eugene Patronis, JR. 3rd edition 2006. The Audio and Acoustic Measurement chapter is great, one of the best explanations of how to use the Nyquist plot and its dimensionaly expanded variant, the Heyser Spiral.

Don Davis worked with many of the greats in audio and had a hand in shaping audio as we know it today, he is also the Father of SynAudCon. Eugene Patronis, JR. is Professor of Physics, Emeitus Georgia Institute of Technology. They are both fun to read.

Time Delay Spectrometry, an Anthology of the Works of Richard C. Heyser on Measurement Analysis and Perception.

Its a pitty, Richard's remarkable insight and his work is so often copied, and so seldom acknowledged. These are the writings from the man who really put it all together. Prior to Heyser, real life data from manufactures was usually frequency vs. level responses and rarely phase response. Cancer took him in 1987 I believe, the depth of his works are still not fully realized.

If you really want to dig into how and why loud speakers behave as they do, and how to "correctly" (read and you'll see) measure them, I believe this is the book.

On the fun side, The Human Side of Engineering by Alger. 1972
Tales of General Electric Engineering OVer 80 Years. From about 1885 or so. Very cool!

I hope to find something like it about Bell Labs in the hey-day. Anyone know of some?

There is a new entry come to town. Ethan Winer has written a tome called The Audio Expert. It looks far reaching, and I have benefited from his writing in the past.

It is on Amazon, but I have ordered it from his web store. For a few more bucks the extras seem a steal.

Can't recommend it until it is in my hands, but it looks very promising for souls like myself.

Yes, I'll recommend it. Old hat to some experts here, but I learned a lot. It does have a very wide perspective.

BTW, it arrived promptly. It just took me a long time to get around to recommending it.

. 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.

I have praised this book elsewhere on the Forums here and I cannot concur more. Highly recommended.
