Sound-intensity-dependent compensation for the small interaural time difference cue for sound source localization.
Interaural time difference (ITD) is a major cue for sound source localization. However, animals with small heads experience small ITDs, making ITD detection difficult, particularly for low-frequency sound. Here, we describe a sound-intensity-dependent mechanism for compensating for the small ITD cues in the coincidence detector neurons in the nucleus laminaris (NL) of the chicken aged from 3 to...
متن کاملSound power emitted by a pure-tone source in a reverberation room.
Energy considerations are of enormous practical importance in acoustics. In "energy acoustics," sources of noise are described in terms of the sound power they emit, the underlying assumption being that this property is independent of the particular environment where the sources are placed. However, it is well known that the sound power output of a source emitting a pure tone or a narrow band o...
متن کاملempirical comparison of the in situ methods for determining sound power of typical embroidery machine located in industrial workroom
sound power is considered as an excellent measure for evaluating the efficiency of noise controls as well as for comparing noise sources in workrooms. this parameter can be determined by sound pressure or intensity based methods in real conditions of workrooms. this paper aims empirically to compare these in situ methods in relation to a typical industrial machine located in workroom in terms o...
متن کاملSound source location modulates the irrelevant-sound effect.
Participants memorized lists of visually presented digits in silence or while ignoring distractor sounds that either came from the front and thus from the direction in which participants' attention was oriented, or from behind. Distractor sounds impaired recall performance, but the largest impairment was observed when the sound source was directionally close to the frontal visual target display...
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...
