Sweet Slab Sounds

Kiwi Company To Make Sweet Sounds For World's Airline Passengers

Slab DSP Limited To Supply U.S. Aerospace Manufacturer With Noise Cancellation Electronics For Passenger Aircraft.

Auckland, 6 August 2002 - New Zealand's Slab Group announced today that its revolutionary noise reduction product would soon be making a big difference to the ears of the world's airline passengers.

Slab DSP (Digital Sound Processing) Limited has secured a commercial contract with In-Flight Peripherals Limited for the supply of noise cancellation electronic equipment to giant U.S. aerospace manufacturer Rockwell Collins.

Rockwell Collins Passenger Systems will start using Slab's noise reduction system in January 2003 with a view to making the product a standard part of their in-flight entertainment package supplied to the world's passenger airlines.

Mark Donaldson, Head of Research and Development for Slab Group says the deal is very exciting for company which has been at the forefront of developing sound systems with active noise reduction specifically designed for commercial passenger aircraft.

"Slab has invested in a purpose built research studio which includes part of an aircraft cabin with the aim of bringing our unique, Kiwi designed product to supply the world's commercial airlines with a superior, high quality sound that passengers are unable to get from present in-flight entertainment systems," says Donaldson.

"This technology provides the airlines with a very effective, versatile and cost competitive on board solution for active noise reduction. We are hopeful that the world's airlines will now consider deploying our unique product throughout all passenger classes given the many in-flight entertainment benefits it delivers.

"The Rockwell Collins deal is also significant because of the volume potential and revenue growth it represents for Slab's product. Rockwell supplies and installs most of the world's existing and new airlines with their in-flight entertainment systems, so their adoption of our product is about as big as it gets," says Donaldson.

Donaldson says Slab's proprietary product will be incorporated in a small audio-jack for installation in the armrest of the passenger seat on commercial passenger aircraft. In-flight Peripherals Limited, a UK-based avionics company, will be responsible for the installation of the product.

"To complete this product Slab has also developed a range of headphones to operate with this integrated noise reduction solution. Airline passengers will connect a special headphone to the noise cancellation audio-jack in their armrest, which monitors the ambient noise conditions and provides an appropriate controlling response that cancels a significant proportion of the problematic noise.

According to Donaldson, Slab's analogue noise cancellation product therefore enables passengers to experience modern in-flight entertainment programming without the disturbing affects of noise normally associated with aircraft travel.

"What this means is that airline passengers can experience sensational, surround sound free from engine noise or other interference. The latest avionics research has also indicated that in-flight entertainment noise reduction systems greatly reduce passenger fatigue and stress which can be particularly beneficial to comfort levels during long-haul international flights," says Donaldson.
