Sound pressure level in a municipal preschool
AIM To evaluate the sound pressure level to which preschool students are exposed. METHOD This was a prospective, quantitative, nonexperimental, and descriptive study. To achieve the aim of the study we used an audio dosimeter. The sound pressure level (SPL) measurements were obtained for 2 age based classrooms. Preschool I and II. The measurements were obtained over 4 days in 8-hour session...
متن کاملLocalisation of Multiple Sounds as a Function of the Duration of the Inter-Sound Gap
One issue that arises in relation to the use of three-dimensional audio displays as a means of conveying spatial information to human operators concerns the ability of operators to track the locations of multiple sounds. We have examined the effect of varying the gap between a target and five distracter sounds on the accuracy with which the target sound can be localised under conditions in whic...
متن کاملLevel discrimination of sinusoids as a function of duration and level for fixed-level, roving-level, and across-frequency conditions.
The ability of listeners to detect level differences between two sinusoidal stimuli in a two-interval forced-choice procedure was measured as a function of duration and level in three conditions: (1) the pedestal was fixed in level and the stimuli in the two intervals had the same frequency of either 1 or 2 kHz (fixed-level condition); (2) the pedestal was roved in level over a 20-dB range from...
متن کاملSound pressure level generated by individual portable sound equipment.
INTRODUCTION The use of Personal Digital Audio Players can cause hearing injuries, as the sound is generated directly in the ear canal. It is believed that different types of headphones can cause different amplifications, since they cause changes in the volume and resonance of the ear canal according to their depth. OBJECTIVE This study aimed to determine the sound pressure to which young ind...
متن کاملThe influence of duration and level on human sound localization.
The localization of sounds in the vertical plane (elevation) deteriorates for short-duration wideband sounds at moderate to high intensities. The effect is described by a systematic decrease of the elevation gain (slope of stimulus-response relation) at short sound durations. Two hypotheses have been proposed to explain this finding. Either the sound localization system integrates over a time w...
