Caption on picture reads: “Two heads are higher than one for Bell Phone Laboratories analysis into the methods individuals find the route of sound. Sensible outcomes of the current ‘double dome’ analysis at Murray Hill, NJ, could be the enchancment of stereophonic radio and TV applications, that are transmitted nationwide over phone amenities. Within the experiments, two microphones within the ears of the dummy, ‘Oscar II’ had been substituted for human ears. Oscar’s head reproduced the ‘shadowing’ of sound by a human head. Individuals taking part within the checks — comparable to Mary Lou Hartig, proven — wore the additional head in order that motions of their heads could be reproduced, for even very small actions affect listening to. The pure sounds obtained in every microphone had been altered electronically by acoustics scientist, R. L. Hanson (proper) and had been delivered to the earphones. Listeners had been requested to level to the obvious route of the altered sound. Usually, the ear that’s nearer to a sound hears it earlier and louder than the opposite ear. Right here, nonetheless, synthetic variations in time delays and depth had been launched, and it was discovered that the issue of depth is extra vital than beforehand believed. If sound reaches one ear first however reaches the opposite ear considerably louder, the hearer is totally confused.”
