Pilot USA PA-1181TH Passive Helicopter Headset.

To make this headset stand out from the others, black chrome hardware has been used to go along with the textured black ear cups to create a very sophisticated look in the cockpit. A full flex microphone boom allows the user to position the noise cancelling electret microphone in the precise place they want it. A washable pillow top head pad along with silicone gel ear seals, gives you the comfort you’ve been looking for. This headset comes with a soft padded headset case.

The headset is cell/satellite phone capable, and has a “true stereo” input jack so that the user can listen to music from a CD player, IPOD®, MP3® or external radio. The cell phone system is designed to work with either newer “Smartphones” that use a 3.5mm (4 conductor) input or older phones that use a 2.5mm input.

Passive headsets cancel sound by blocking sound waves. Sound can be blocked by 3 methods: Barriers, Absorption Material, and Damping Methods. In our aviation headsets, we use the ear cup as walls to enclose the ear and act as an acoustical reflector. The ear cups act as a barrier against the path of noise and eliminates energy of the noise wave. The hard barriers target high frequency noise. We also use different types of acoustical foams to absorb the sound waves and eliminate more energy from the sound waves.

Vibration isolators which include spring steel equipment mounts, plastic and rubber based bushings and grommets all contribute to noise canceling by damping the noise. These vibration isolators absorb noise coming in through the headband and ear cup stirrups and also noise waves that are bombarding the ear cups.
