ITT Enidine Inc. understands noise! Composite fuselage aircraft, with their comparatively high stiffness and low damping, increase the challenge of noise control. ITT Enidine Inc. has developed a series of panel isolators (custom elastomers and elastomeric rod ends) that provide increased attenuation.
These isolators have demonstrated their capability in such aircraft as the Raytheon Hawker Horizon. Developed using impedance techniques, these methods address the persformance of the isolator throughout the desired frequency range. Noise testing capabilities, such as the 4-Pole Linear Transform Method, is used to properly measure noise attenuation.
