The
benefits to student and teacher of a Sound Field system
(any Sound Field system!) are clear and succinct.
For
the system specifier and the installer, there is a wide
range of acoustic, aesthetic, logistical and financial
benefits to the Armstrong i-ceilings Sound Field System
over and above those of our competitors’ solutions… |

Unparalleled even sound coverage:
The i-ceilings Sound Field System is based upon
our revolutionary
i-ceilings
Sound Panels, a unique loudspeaker solution
developed to provide unparalleled levels of even
sound distribution. i-ceilings use ‘NXT’
flat panel speaker technology (sometimes called
‘distributed mode’), which provides
much more even sound coverage (Fig.1) than the
‘hot and cold spots’ characteristic
of conventional ‘cone’ loudspeakers
(Fig.2). |

Fewer
loudspeakers required:
Due to i-ceilings’ even sound distribution
characteristics, fewer speakers are required
in comparison with conventional ‘cone’
ceiling or wall mounted speakers. This provides
significant reductions in installation time
and, in many cases, clear cost reductions. |
| |
|
Reduced
loudspeaker theft or vandalism:
i-ceilings Sound Panels are developed by
suspended ceiling market leaders ‘Armstrong’
to exactly match their range of acoustic
ceiling tiles. As the i-ceilings loudspeaker
is visually identical to the rest of the
ceiling, it is virtually impossible to identify
them by eye, therefore greatly reducing
any possibility of their theft or damage
in public access or vulnerable areas. |

i-ceilings
loudspeakers are unidentifiable in the ceiling.

Reduced
microphone feedback (or ‘microphone howl’):
As Sound Field systems use wireless (or ‘roaming’)
microphones, there are limitations to the audio
system placement to ensure microphones do not
feedback (or ‘howl’).
The NXT flat panel loudspeaker technology used
in i-ceilings Sound Panels greatly reduces the
possibility of feedback, allowing the teacher
to roam freely throughout the classroom and providing
easier, more flexible audio system design. |

Cost-effective,
multiple-room systems without signal crossover:
Sound Field Voice Reinforcement in the
classroom really works! Which is why
the majority of schools, colleges and universities
that have a system, in fact have systems
in many or all of their classrooms.
Most Sound Field systems use ‘RF’
(Radio Frequency) wireless microphones,
which have limitations to the number of
frequency channels available and high cost
implications for increased numbers of channels.
i-ceilings Sound Field provides an ‘Infrared’
wireless microphone solution which
negates the difficulties of number of frequency
channels and high cost implications. Infrared
uses light (just like your TV remote control)
rather than RF to transmit the microphone
signal. The infrared signal cannot ‘overflow’
into adjoining classrooms as light will
not transmit through walls. This allows
the same simple and highly cost effective
system to be used in any number of adjacent
rooms without the need for multiple frequencies. |

Secure
signal for privacy rooms:
Furthermore, unlike radio frequency systems,
the characteristics of infrared ensure that
unauthorised parties outside of the room
cannot receive the transmission signal of
the voice. |
