## Summary

Harvey Fletcher's own paper opening the 1934 AIEE symposium on auditory perspective — the technical literature of the Bell Labs stereophonic program, published under Fletcher's name rather than described by a later biography. It sets out the requirements for picking up an orchestra, carrying the signal a long distance, and reproducing it in a large hall.

## Useful Claims

- The paper of record is Fletcher, H., "Auditory perspective — Basic requirements", *Electrical Engineering*, vol. 53, no. 1, pp. 9–11, January 1934. DOI 10.1109/EE.1934.6540356.
- Fletcher is the sole author, affiliated to Bell Telephone Laboratories, Inc., New York. The stereophonic work is his in the technical record, not only in retrospective accounts.
- The abstract states the paper's subject as "the fundamental requirements involved in a system capable of picking up orchestral music, transmitting it a long distance, and reproducing it in a large hall" — the Philadelphia-to-Washington problem, stated as an engineering brief.
- It is explicitly the first paper of a symposium, not a standalone result. The companion papers in the same series are Steinberg and Snow, "Auditory perspective — Physical factors" (DOI 10.1109/EE.1934.6540357), which reports that good auditory perspective is obtainable with two or three channels rather than the ideal infinite number, and Wente and Thuras, "Auditory Perspective — Loud Speakers and Microphones" (DOI 10.1109/T-AIEE.1934.5056477, carried in *Transactions of the AIEE* rather than *Electrical Engineering*), which treats the transducers used in what it calls "the Philadelphia-Washington experiment".

## Reliability Notes

Primary tier by type, with one caveat worth stating rather than hiding: *Electrical Engineering* was the AIEE's own journal and these papers were presented at the AIEE Winter Convention in 1934. That is the contemporary professional-society literature and it is where this work was published, but 1930s AIEE practice is not modern anonymous peer review, and the `peer-reviewed` tier should be read as "the technical literature of record" rather than as a modern refereeing claim.

Confidence is Medium because the article body has not been retrieved — IEEE Xplore is paywalled. The bibliographic facts above come from the Crossref record for the DOI, and the quoted abstract line from the publisher's abstract. **No figure or date from the demonstration is asserted here.** The April 27, 1933 Constitution Hall demonstration, the three-channel configuration, the frequency response achieved, and the 1931–1932 recording sessions are all claims the fact page makes from other sources; none of them is carried by this page, and none should be added to it without the article text in hand.
