Hall reverberation cloaks loudspeaker defects in live-versus-reproduced demonstrations

Evidence

These events avoided the circle of confusion problem (see Figure 1.8) because custom recordings were created for reproduction through specific loudspeakers at those events. But there is another factor. Most of the comparison demonstrations took place in concert halls or auditoriums. The hall sound is a huge embellishment to live performances, and it similarly benefits these reproduced sounds. Villchur (1964a) recognized this, saying: “Playback at the recording site may not sound as similar to the live music as at the actual concert, because the reverberation which will cloak both live and reproduced music equally is missing.” His choice of the word “cloak” is interesting, considering the normal meaning of the verb: to hide, cover, or conceal. — Toole, Floyd E, Sound reproduction- the acoustics and…, 398

Categorization

• XREF: The ‘circle of confusion’ concept ties directly into the channel’s existing audio/soundscape reading; hall reverberation cloaking reproduced sound parallels how ambient sound in general shapes perceived quality. — connects to: Shared room acoustics let 1920 phonograph demos fool live audiences; Live-versus-reproduced demonstrations were contrived marketing that flattered flawed loudspeakers; Recorded venue acoustics masked loudspeaker resonances that technical signals reveal (+3 more)
• SEED: Angle: how demonstration environments systematically flatter audio gear versus typical home listening—a cautionary piece on judging hi-fi in showrooms versus small rooms.
