The Acoustics of Miniskirts

October 1969: UCLA Professor Vern O. Knudsen assembled ten young women wearing miniskirts in a reverberation chamber and fired a blank cartridge from a pistol. He did this to prove his hypothesis that bare legs revealed by a miniskirt will reflect more sound than legs covered by a long skirt.

His hypothesis confirmed, he warned that miniskirt wearers might disturb the carefully engineered balance of sound in concert halls by reflecting more sound. He noted: "We must be acoustically thankful that they don't wear bikinis."

Oddly enough, this wasn't the first time a scientist had warned of the acoustic danger of short skirts. Back in 1929, Colgate University Professor Donald A. Laird had issued a very similar warning: "He quoted scientific reports to prove that shortening of women's skirts has added to noise by removing some sound deadening surface."

“We must study these young ladies in miniskirts very carefully…”

I worked on a sound mixer board in a church I attended and you would be surprised at the difference between an empty hall rehearsal and a full hall performance. People absorb sound waves to the level that I had to boost the amplification by a good 5 percent.
