| This is accomplished in several ways. The first is by the introduction of a metal band, and different styles of foam inside the ear cuffs which disperses ambient noise. This alone reduces noise by 2 db's. Then by using an electronic noise canceling microphone noise is reduced by an additional 30 db's. According to Tim Bruno President of RAD this "virtually eliminates wind and engine noise during ultralight aircraft pilot to pilot conversations or transmissions over aircraft band radios." The intercom box which is the heart of the system allows pilots to control their own volume plus adjust "threshold attenuation" which in the air can help reduce another  40 to 43 db's of noise. This is also used to adjust for the style of voice, that is women and children who tend to have softer voices can adjust the system for better communication. Also found on the box are two transmit and receive jacks. These allow connection of an aircraft band radio, CB radio, CD player, cell phone or in conjunction with a video camera to narrate while shooting video. The fourth jack allows the system to run a 12 volt system rather than the built in 9 volt battery that would normally be used. The T2 system is available for use as a headset with a radio, a headset with a removable helmet shell, or a helmet with the audio components built into it. RAD also builds communication systems for specific applications. These include two helmet and intercom systems for trikes. One is an open faced audio equipped helmet with a flip up visor which is available in several different tints. The second is an audio equipped, double visor, open face helmet with a flip front, and a breath deflector which is ideal for winter flying. RAD has been producing helmets and intercom systems for high noise environments since 2000 and offers a one year warranty on parts and labour. For more information contact: |
