- The acoustics of vowels can be visualized using spectrograms, which display the acoustic energy at each frequency, and how this changes with time.
- The flat position eliminated the problem of acoustic energy radiating from the back of the enclosure, smearing the forward output with multi-path arrival times.
- When a noise is closer to one ear than the other, its acoustic energy will reach that ear faster and louder than the other ear.
- Recording is by mechanical means and the vibrations from acoustic energy, transferred to a cutting needle, make the needle cut a deeper or shallower groove.
- Acoustic energy is variation in the air pressure that can be represented as sound waves, which are then perceived by the human auditory system as sound.
- Pressing a key on the piano's keyboard causes a padded ( often with felt ) hammer to strike steel couples the acoustic energy to the air.
- The original device is based upon a suspension of asymmetric particles in a thin fluid layer which, when acted upon by acoustic energy, produce visual reflectivity changes.
- Since the ultrasonic transducer is used both for transmitting and receiving the acoustic energy, it is subject to a period of mechanical vibration known as ringing .
- Sound can travel through water for enormous distances, prevented from dissipating its acoustic energy by boundaries in the ocean created by water layers of differing temperatures and densities.
- This also minimizes the negative effects of acoustic energy that would otherwise ( as with a sealed enclosure ) be reflected back to the driver in a sealed cavity.
- This problem is distinct from biologic interference caused by acoustic energy generated by marine life, such as the squeaks of porpoises and other cetaceans, and measured by acoustic receivers.
- Transmission loss does not involve the source impedance and the radiation impedance inasmuch as it represents the difference between incident acoustic energy and that transmitted into an anechoic environment.
- Engineering and wind-tunnel tests revealed that the geometry of the rear fuselage and the engine exhaust created flutter-inducing turbulence that was aggravated by the high-frequency acoustic energy from the exhaust.
- For example, an explosion is the result of a chain reaction that transforms potential energy stored in chemical, mechanical, or nuclear form into kinetic energy, acoustic energy, and electromagnetic radiation.
- In the past, such calls for countermeasures before flight _ such as muffling material, baffles and mounting brackets that do not transmit acoustic energy _ were ignored to control costs.
- Liners are applied on the internal walls of the engine nacelle, both in the intake and by-pass ducts, and use Helmholtz resonance principle for the dissipation of incident acoustic energy.
- "' Geometrical acoustics "'or "'ray acoustics "'is a branch of acoustics that studies propagation of sound on the basis of the concept of rays considered as lines along which the acoustic energy is transported.
- He tested the range of frequency and found that transmitting acoustic energy between 18 kilohertz and 36 kilohertz, or just above the level that humans can hear, had a devastating effect on the larvae.
- This technology focuses acoustic energy into a fluid sample in order to eject droplets as small as a millionth of a millionth of a litre ( picoliter = 10 " 12 litre ).
- These standing waves can be considered a temporary storage of acoustic energy as they take a finite time to build up and a finite time to dissipate once the sound energy source has been removed.
