General Description
The Telex Air3100 is a medium-weight noise-reduction headset with
amplified, noise-canceling, electret microphones. The Telex Air3100L is a
headphone only and does not have a microphone. They both have a
noise reduction rating of 21 dB, and are suitable for use in moderately
noisy aircraft. All models feature a unique headband design that
distributes ear cushion pressure evenly over the entire ear with no
pressure points, unlike conventional designs which apply more pressure
on the bottom of the ear than on the top. An added advantage of this
design is that the headset folds into an extremely compact shape for
storage. The Air3100 headset is approved for aircraft use under FAA
TSO’s C57a and C58a. The Air3100L headphone is approved for aircraft
use under FAA TSO’s C57a.
Design Features
(See Figure 1
)
Comfortable foam-filled headband pad and ear cushions. The headband
pad evenly distributes the headset weight, with no pressure points, for
maximum wearer comfort. The ear cushions combine comfort and light
weight with excellent acoustic seal. An outer urethane layer ensures long
life. Gel-filled ear cushions are also available for this headset for users
who prefer this type. All cushions are field-replaceable.
Boom Microphone:
The boom arm features a sealed ball-and-socket
joint and flexible boom for precise microphone placement on any head
size. The boom rotates overhead for microphone placement on either
side of the head. The microphone cartridge features a noise-canceling
electret element. The cartridge snaps on and off for easy replacement.
The microphone amplifier is in the microphone cartridge. It operates on
current supplied by the aircraft radio via the microphone jack. The
amplifier output level is adjustable through an opening in the microphone
assembly.
Cordage:
The microphone cordage is protected inside the boom arm.
Shielded wire throughout the headset protects against RFI and EMI.
Strain-reliefs on all cords provide maximum durability.
Sound Attenuation Data:
The following measurements for the Telex
Air3100 and AIR3100L Headsets were made according to the American
National Standard Institute (ANSI) S3.19-1974 by Paul Michael and
Associates. These laboratory-derived attenuation data are for comparison
purposes only, as the amount of protection afforded in field use is often
significantly lower depending upon how the headphones are fitted and
worn.
