It is demonstrated that the suggested layered metamaterial exhibits highly superior acoustic insulation performance close and above the acoustic coincidence range, thanks to the drastic increase of its structural damping properties implied by the NS elements.
Gibbon songs are highly complex acoustic structures, and it may well be possible that there were other important acoustic cues present that we overlooked.
Unfortunately, amplification robbed the strings of some of their natural beauty, and a highly reverberant acoustic — the venue was the Church of St. Paul the Apostle, near Columbus Circle — rendered many details indistinct.
We can see that recognizing the keywords is particularly important in highly adverse acoustic conditions.
All these studies suggest the importance of keeping the link between the two highly correlated acoustic and visual channels.
In certain cases, a natural frequency associated with a minimum viscous damping and a maximum of total damping (indicating highly efficient acoustic radiation) is possible with such a frequency.
Indeed, such methodology is known to be effective when the response of the system is a smooth function of the frequency, like in the case of highly dissipative acoustic treatments.
Starting with a delicate but highly ominous acoustic intro, the track festers into a terrifying fade-in that in turn heralds a riff of warp-speed brutality.
For example, the anterior temporal regions (anterior STG, MTG, and intervening STS) that were selectively activated during improvisation appear to play an integral role in processing complex features of highly structured acoustic stimuli, including music [42].
How humans extract the identity of speech sounds from highly variable acoustic signals remains unclear.
