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.
