AYRLITE 2071 Acoustic Honeycomb Panel DESCRIPTION AYRLITE® 2071 is a revolutionary fibre-free, lightweight sound absorbing aluminium honeycomb panel. It is faced on one side with a flat micro-perforated aluminium sheet (AYRLITE® 2071 | FLAT) or with a corrugated microperforated aluminium sheet (AYRLITE® 2071 | CORR). The panel has outstanding sound absorption, particularly at low frequencies. The sound absorption properties are unique and remarkable for such a low weight and fibre-free material. Being all-aluminium, AYRLITE® 2071 has very good fire performance. Health and safety features are also excellent because there are no loose fibres. Although principally developed for high-performance marine vessel interior applications, AYRLITE® 2071 is also attracting interest in other marine sectors, restaurants, construction and mining industries. • Fully compliant with European Union Marine • Outstanding sound absorption especially at low frequencies Equipment Directive (EU-MED) 96/98/EC.

AYRLITE 2071 Acoustic Honeycomb Panel SOUND ABSORPTION AYRLITE® 2071 achieves very high sound absorption The absorptive frequency range can be adjusted to as low without using combustible materials, or conventional as 250Hz, where effective sound absorption is difficult to fibrous materials. achieve using traditional materials. It is able to reduce interior noise and improve interior Sound absorption coefficients to ISO 354-2006 for the acoustic quality. two different types of surface finishes are shown in the graph below. The peak absorption frequency of AYRLITE® 2071 can be tailored to the...

SOUND TRANSMISSION LOSS As well as outstanding sound absorption capabilities, AYRLITE® is also very good for Sound Transmission Loss. The Sound Reduction Index to ISO 717.1 for the AYRLITE® | FLAT and AYRLITE® | CORR can be found in the graph below. The Transmission loss can be even further improved by embedding Quadzero® or similar material into the panel.
