Heritage introduces quiet helo cabin ‘cocoon’
To some, helicopters are the essence of noise; to others they make the music of commerce.

To some, helicopters are the essence of noise; to others they make the music of commerce. Regardless, helicopters are known to rumble and clatter and roar and whine, all the while thrashing the air about amid a whir and blur of rotor blades, making cabin noise a foregone conclusion, and normal conversation difficult at best. But that is about to change, according to Ed Bolden, president of Heritage Aviation.

At facilities in the Dallas suburb of Grand Prairie, Heritage aircraft interior specialists are putting the finishing touches on the company’s first “Iso-Quiet Cocoon Interior,” creating a helicopter cabin in which the sound level is expected to register 75 dBA or less. According to industry experts, the dBA level in a typically configured helicopter cabin is in the high-80s, and sometimes in excess of 90 dBA.
