 note = {The experiment described in this paper was designed to investigate the acoustics of living spaces, with the aim of fostering the design of more comfortable environments acoustically optimized for infant childcare. Recently, incidents of infant abuse reportedly triggered by excessive crying have been on the rise. One cause, we hypothesized, could be the changing structure of Japanese homes. Using recordings of crying meant to be maximally stress-inducing to mothers, the experiment was designed to examine the effect of a change in the acoustic environment upon a listener's perception of an infant's voice. Subjects were asked to listen to two recordings of the same voice at 90dB±1dB, the first given a reverberation time of 270 ms (simulating an “anechoic environment”), and the second with a time of 970 ms (an “echoic environment”). Subjects reported that they felt “tired,” “uneasy,” and that they experienced “headache” and “ringing in the ears” at a higher rate in the echoic than in the anechoic environment. However, responses indicating hypothetical maternal behavior such as a desire to“determine why the baby is crying”or to“calm the baby”were reported at approximately equal rates in both environments. These results indicate that an echoic environment may exacerbate the stress experienced by a mother listening to a crying infant.
Further research examining the ways in which actual mother-infant pairs play and communicate in varying acoustic environments is planned., text, application/pdf},
