3. Resonance is the vibration in
an object because there are
other objects that vibrate,
this happens because an
object vibrating at the same
frequency with the frequency
of affected objects.
4. 1. Mechanical resonance
Is the tendency of a
mechanical system to absorb
more energy when the
frequency of oscillation of the
system matches the natural
frequency of vibration than it
does at other frequencies.
5. 2. Acoustic resonance
Is a branch of mechanical
resonance associated with
mechanical vibrations across the
frequency range of human hearing,
in other words the sound. For
humans, hearing is usually limited
to frequencies between about 20 Hz
and 20,000 Hz (20kHz).
6. Resonance occurs when
the system is able to
store and easily transfer
energy between two or
more different storage
modes (such as kinetic
energy and potential
energy in the case of a
pendulum).
Process of Resonance
7. In physics, resonance is the tendency of a
system to oscillate at larger amplitude at
some frequencies than at others. This
system is known as the resonant
frequency .At these frequencies, even
small periodic driving forces can produce
large amplitude oscillations, because the
system stores vibrational energy.
Process of Resonance
8. d. Guitar or violin
The air that was in the
box the guitar will resonate
when plucked guitar strings /
violin swiped on.
a. Ribbon Sounds in Humans
Resonance can bring benefit to us because it can amplify the sound as it
did in the tools that work based on such resonance below:
b. Thin membrane in the ear
Eardrum membrane is
very thin so it is easy to resonate.
c. Kentongan
Resonance occurs in
the air column is created in the
middle of the gong
9. a. Damage to the thin
membrane found in the ear
b. The sound of vehicles passing
in front of the house to vibrate
the glass windows of the house
d. Effect of wind speed on a
bridge in the Strait of Tacoma,
United States, producing
resonance that causes the bridge
collapsed
c. Noise that is produced by thunder resonate
with glass house so that vibrate and can result
in broken glass.
f. Central Tower collapse
Konigs Wusterhausen
10. A . Technically, the control can be done in various ways:
a. Control of the sound source, such as the use of
materials that do not resonate, close to the sound source
material that can absorb sound,
b. Control of the media
carrying sounds, by isolating
the sound source and the
distance from the sound
source.
c. Controlling noise at the
receiver. This control is the
last step in noise control such
as the use earplug or earmuff.
11. B. Administratively, the man
himself for such conduct
audiometric testing and set
the target as long as he was
at the source of sound for 8
hours on the intensity level
of 85dB
