HRTF filtering effect. A head-related transfer function (HRTF) is a response that characterizes how an ear receives a sound from a point in space. As sound strikes the listener, the size and shape of the head, ears, ear canal, density of the head, size and shape of nasal and oral cavities, all transform the sound and affect how it is perceived, boosting some frequencies and attenuating others.
The Space Sciences Laboratory (SSL) at Berkeley, California was initiated in 1958 by a committee of faculty members who recognized that emerging rocket and satellite technology opened up new investigative realms for the physical, biological, and engineering sciences.
add some glue (e.g. a layer of glue is often added on the top of television coils ; over the years, this glue degrades and the sound level increases) change the shape of the coil (e.g. change coil shape to a figure eight rather than a traditional coil shape) isolate the coil from the rest of the device to minimize structure-borne noise
In space, no one can hear you scream -- but you may hear a knock. When he was alone in a spacecraft in 2003, astronaut Yang Liwei reportedly heard a "knock" despite being alone.
Janet G. Luhmann (born 1946) is an American physicist and senior fellow of the Space Sciences Laboratory of the University of California, Berkeley. [1] She has made major contributions to a wide range of topics in planetary, solar, magnetospheric, and heliospheric physics.
The resonance condition is given by = , which is when the neutrino system experiences resonance and the mixing becomes maximal. For very small θ , {\displaystyle \ \theta \ ,} this condition becomes ℓ ν ≈ ℓ 0 , {\displaystyle \ \ell _{\nu }\approx \ell _{0}\ ,} that is, the eigenfrequency for a system of mixed neutrinos becomes ...
A Laplace resonance is a three-body resonance with a 1:2:4 orbital period ratio (equivalent to a 4:2:1 ratio of orbits). The term arose because Pierre-Simon Laplace discovered that such a resonance governed the motions of Jupiter's moons Io , Europa , and Ganymede .
Now NASA is stepping in to provide some insight into what could actually be causing this scary pattern. NASA scientists believe the ominous noises could potentially be the "background noise" of ...
