Knowing that the acoustic resonance
of the air cavity is inversely proportional to the square root of the acoustic stiffness, it could be deduced that the small volume of the air cavity would result in a high-frequency acoustic resonance

frequency analysis," Journal of Agricultural Engineering Research, vol.
The cavity length was L = 20 mm, and the depth was D/L = 0.5, where the acoustic resonance
such as a depth mode does not occur.
A cavity flow without acoustic resonance
does not generate self-sustained oscillations or intense tonal sound in cavity flows at low Mach numbers in the turbulent boundary layer.
Moving the first acoustic resonance
higher in frequency (above 20 Hz) enables the measurement to capture the first acoustic resonance
of the combustion chamber.
Trapped acoustic resonance
is most simply described with an analogy: the ringing of a bell.
Finally, before the metal discs are sent out to drummers the world over, they are aged for several months to achieve the perfect acoustic resonance
Operationally, the unique ActiveMetal technology has its basis in trapped acoustic resonance
combined with rugged metal housings.
The program provided both batch output and interactive plotting in which the acoustic resonance
shapes could be animated.
Noise Reduction for Acoustic Resonance
of Cascade Wings
Nevertheless, sound from the flame will excite structural or acoustic resonances
at certain frequencies.
