Sound iscreated when an objectvibrates(振动).Thevibrations travel in waves.Sound waves reach our ears.The ears send a message to the brain. That's how wehear different sounds! A sound can be loud or quiet Itcan have a high pitch(音高)or a low pitch. Here area few different sounds.A...
that quadrupole in turbulent flow takes an essential role in generation of aerodynamic sound, but the mechanism has not been fully understood. The present paper devotes numerical visualization on how acoustic field is formed when a quadrupole is set near an elliptical object. The acoustic field is...
The first component reflects both living and nonliving objects (e.g., missile, lion, train, and bull) that capture our attention via multiple sensory modalities. Graspability has a substantial negative loading on this first component, consistent with the observation that loud, potentially harmful ...
As a personal rule, I always replace the stock fans with aftermarket ones that push more CFM. I also try to fill up every slot I can with an aftermarket fan. My old PC was LOUD from all the fans, it sounded like a helicopter taking off in office constantly. This one has more fans...
Given that clients exist in many different tasks, a sound server is required to centralize the processing in a single task. An alternative implementation has been explored which handles signal processing in a separate task per audio component. No server is needed for audio processing. This is ...
A relay in the anode circuit of the oscillator valve in audio oscillator 30 has contacts which close the circuit of a bell 32 and further contacts which remove bias from the oscillator valve such that, after an initial echo, it oscillates continuously and the bell remains ringing until a ...
to reset the count-down timer every time another triggering sound is detected during that time, and (3) to return to sleep mode only when the count-down timer has counted down. The detector of the invention thereby provides an adaptive disable, that adapts itself to the noise environment, ...
For example, one or more physical features of companion object 202 may be customized in accordance with companion object profile 272 such that companion object 202 has physical features similar to those of companion avatar 268. Alternatively, companion object 202 may be customized to have physical ...
and musical string means mounted in said horn free of the sound source so that parts of said means lie within said passage and parts thereof lie adjacent to the source of sound outside of said passage but within the horn, said string means being closely adjacent to the wall of the horn,...
5.System according to claim 2, including said personal computer (200) including a loud speaker (202) forming said transmission means for the acoustic time-setting signal (50), characterised in that said personal computer is connected to a wide area computer network, such as the internet, and ...
