My 3D - RecordingSystemssimulate all acoustic relevant components of the human
auditory experience, especially spatial hearing. This system captures aurally
accurate spatial recordings of sound events and locks in their exact room
position, with only 2 channels. Recording up to 24bit 196k capturing the full
Frequency Response at High Definition resolution. Add 3D on top of that and you
have very real sounds. Designed for playback on traditional stereo speakers,
giving the listener a full 3D representation of the sound event. This includes
sound above, below and outside the realm of traditional stereo speakers. The
depth perception, as well as Sonic quality, is unbeatable. Every Sound
in the 3D Sound Library, of Chuck Plaisance, was recorded with these 3D recording systems except for
the underwater recording of Humpback Whales, Dolphin, choral reefs and fish.
Special underwater transducer microphones where used for those underwater recording sessions.
Covering up the ears is an unlikely approach to evaluating
sound. Yet that is what conventional analysis techniques in acoustic technology
actually amount to. This is because recordings made with conventional
measurement microphones are not appropriate to aurally-equivalent evaluation of
sound situations, since essential acoustic information, such as the spatial
constellation of sound sources and the selectivity of aural perception, cannot
be captured. Yet it is actually the three-dimensional localization of sound
sources and the way acoustic signals are processed by the human auditory
apparatus, which are vital, factors in how sound is perceived.
Humans are able to localize a sound source spatially. Human
hearing completes this localization automatically, based on the delay and level
differences of the acoustic signal at either ear. This is because the outer ear
produces directionally dependent filtering of the acoustic signal. The filter
effect is based on the modification of sound wave propagation through
attenuation, diffraction, reflection and resonance. In this process, the
geometrical (anatomical) characteristics of the head and shoulders, along with
the ear pinna, play a decisive role. The ability of human hearing to select
individual sound sources when exposed to a noise background is also based on
the ability to localize. Using an arrangement of two measurement microphones as
"ear" cannot simulate binaural hearing. Aurally accurate,
true-to-the-original recordings are only possible by taking account of the
acoustic filtering properties of the head and ears.
The characteristics of human hearing are very different from
those of conventional sound sensors. Signal processing in the human ear,
involving identification of amplitude distribution, spectral composition and
time structure, is extremely complex. The listener perceives a comprehensive
auditory impression of an acoustic event. At the same time, as listeners, our
acoustic memories are very short. The Artificial Head measuring technology
allows aurally accurate recording of acoustic signals, together with storage of
acoustic events. Playback of Artificial Head recordings creates the same
auditory impression as if the listener had been able to experience, directly,
the original sound event.
