Psychologists at the U.S. Navy Electronics Laboratory have tabulated results of the hearing survey of thirty‐seven hundred people at the 1948 San Diego County Fair. The investigators found that men who work in noisy areas show greater than normal hearing losses to high frequency sounds but gain slightly in their ability to distinguish low frequency sounds. Investigators also found that musically trained persons had an above‐average ability to hear weak sounds of various pitches at various levels as opposed to those who had no musical training. The tests also confirmed that women are able to distinguish high‐pitched sounds with greater ease than men of the same age group.
