The response exhibits a peak at 250 Hz, which is the result of a l/4 cavity-length resonance caused by the acoustic wave impedance mismatch at the baffle opening. The peak is easily equalized. If measured at a large distance, where front and rear radiation from the baffle combine, the ...
When placed in a BasePart or an Attachment, this object will emit its sound from that part's BasePart.Position or the attachment's Attachment.WorldPosition. In this placement, a Sound exhibits the Doppler effect, meaning its frequency and pitch varies with the relative motion of whatever ...
Both male and female Mannophryne trinitatis use visual displays during social interactions, and, in addition, this species exhibits sex role reversals. Females of M. trinitatis establish territories around boulders and rocks in streambeds. Females perch on top of large boulders and challenge ...
Interference between repeated reflections of sound from the boundaries of an enclosure that is not highly absorbent creates a spatially and temporally complex field that exhibits five principal features: resonance associated with acoustic modes; reverberation, in which the sound energy density decays approx...
1. For a phononic crystal structure to exhibit wave-functional properties, the absorption length is at least an order of magnitude longer than the elastic wavelength. This weakly damped regime is referred to as the metamaterial regime in the literature26. In this paper, we consider only the ...
Sensory cortices can be affected by stimuli of multiple modalities and are thus increasingly thought to be multisensory. For instance, primary visual cortex (V1) is influenced not only by images but also by sounds. Here we show that the activity evoked b
The response exhibits a peak at 250 Hz, which is the result of a ë/4 cavity-length resonance caused by the acoustic wave impedance mismatch at the baffle opening. The peak is easily equalized. If measured at a large distance, where front and rear radiation from the baffle combine, the...
This equation exhibits also one of the most remarkable features of the sonic velocity in homogeneous two-phase mixtures, i.e., it can be very much smaller than that of either of its constituents. This is illustrated in Fig. 4.13, where the speed of sound in an air/water bubbly mixture ...
Shot noise exhibits since the current is not a continuous flow but it is the sum of discrete pulses in time where each pulse corresponds to the transfer of electron through a conductor. Shot noise is caused by the thermal motion of electrons and occurs in any conductor having resistance R. ...
The sound insulation property of a glass panel can be characterized by Sound Transmission Loss (STL). It is well known that sound transmission through glass exhibits coincident effect. Glass has a specific critical or coincident frequency at which the speed of an incident acoustical wave in air ...
