Differential Effects of Noise and Music Signals on the Behavior of Children

Effects of Telephone Ring on Two Mental Tasks Relative to an Office

“…The loudspeaker was placed at the distance of 1)5 m$ 1 cm in front of the subject. The running ACF and IACF of the telephone ringing was measured by the diagnostic system of sound "elds [5] with the integration interval of 0)2 s.…”

A Theory of Primary Sensations and Spatial Sensations Measuring Environmental Noise

“…E!ects of noise on mental tasks can be interpreted as an interference phenomenon between the task performance and the hemispheric dominance [24,25]. Temporal factors extracted from the ACF are associated with the left cerebral hemisphere and spatial factors extracted from IACF are much concerned with the right [1].…”

“…The spatial direction of re#ection to the listener (IACC and '!! ) and the delay time of re#ection t , as included in equation (24), express this threshold [20]. It is worth noticing that the intelligibility of single syllables as a function of the delay time of a single re#ection is well calculated by the four orthogonal factors extracted from the short-term ACF analyzed for the piece between consonant and vowel sounds [3,4].…”
