This paper describes the design of a frequency shifter to suppress acoustic feedback, to be studied by the experimental method.
Simulation results quite coincide with test ones, showing that the simulation model well reflects the acoustic characteristics of the real structure of exhaust muffler.
“Soldier of Love” is so bereft of saxophone and leans so heavily on acoustic guitar that it’s almost an ambient version of country music, which suits the singer’s strengths just fine.
The cloaking technology also may affect nonlinear acoustic phenomena.
Unlike optical systems, acoustic check systems can bother the passengers of a vehicle a lot.
These 'trees' provide seating, shade and acoustic absorption and at night they serve as an illuminate bodies which fill the room with white or blue glowing light.
The unfamiliar tones of classical music can disperse loiterers, while big sound-blasters, known as “long-range acoustic devices” (LRADS), have been deployed against protesters in some American states.
Once, I backpacked around Europe and I brought an acoustic guitar with me.
Time after time, the strings build and build, sometimes soaring off into the ether, other times making way for a solitary bass line or acoustic rhythm.
Even at this distance, the stresses are too great for well-behaved acoustic transmission.
But there will be many other applications to follow, not just in thermal, acoustic and IR shielding for vehicles and shelters.
Test method for bulk acoustic wave attenuation of piezoelectric lithium niobate crystals
In transforming from acoustic folkie to electrified rocker, a process begun in earnest on side one of 1965's Bring It All Back Home, Dylan rewrote the rulebook for pop music.
And some have the long-range acoustic device, a sound cannon that can be used to issue verbal warnings, or deafen anyone who stands in its path.
wire type acoustic delay line
One advantage of acoustic detection is that sound travels rather better in water and ice than light does.
An acoustic detector, also in the armband, then calculates which part of the display you want to activate.
