  • Barry wins cabin-noise deal for Northwest DC-10s

    News | 30 Apr 1997 09:26

    <p>Barry Controls Aerospace's Active Tuned Mass Absorber (ATMA) has been selected by Northwest Airlines to reduce cabin noise in its 173 McDonnell Douglas (MDC) DC-9s. </p> <p>The system has been on trial with the airline for two months and was selected after a competitive evaluation against a noise-suppression system produced by Lord. The ATMAs replace MDC-built vibration absorbers and reduce structure-borne noise by detecting the actual engine vibration frequency, processing the data and optimising the absorbers to connect to the engine frequency. </p> <p>The contract award coincides with the granting of a US Federal Aviation Administration supplemental type certificate on 16 April, covering the use of the device on all marks of DC-9s and MD-80s. Installations of the system, which reduces overall and tonal noise by up to 90% at the noisiest rear seats, are due to begin in June. The full fleet is expected to be retrofitted by June 1998. </p> <p>&nbsp;</p>http://www.flightglobal.com/news/articles/Barry-wins-cabin-noise-deal-for-Northwest-DC-10s-2337/

    <p> Barry Controls Aerospace is demonstrating a new noise-suppression device which is designed for McDonnell Douglas (MDC) DC-9s, MD-80s and other aircraft with tail-mounted engines which are prone to vibration-induced noise. </p> <p>The Active Tuned Mass Absorber (ATMA) was developed in conjunction with Oregon-based acoustic-vibration specialist Hood Technology, and is expected to receive US Federal Aviation Administration supplemental type certification this month. The system has already been selected by a corporate DC-9 user and by Midwest Express airlines, which plans to equip its fleet of 23 DC-9-31s with it. Flight testing was completed on two DC-9s in August and September 1996, and the system was demonstrated at 1996's National Business Aircraft Association meeting in Florida. </p> <p>The ATMA system consists of eight absorbers, replacing the original MDC-made tuned vibration absorbers which mount to the engine yoke.
