Aaac 6 Star
Mike Fowler
The 2mm high density foam underlay offers acoustic certifications achieving up to 5 stars on the AAAC test, making them a common choice for apartments and units where strata management may require noise reduction when installing flooring.
Powerful attitude determination for small satellites. The ST400-T star tracker, developed by AAC Hyperion, is aimed at microsatellite systems. With increased attitude determination accuracy and improved radiation tolerance compared to its little brother, the ST200, it enables more demanding missions.
The ST400-T is a standalone, low mass, low power star tracker, which renders attitude determination capability to small satellites. The ST400-T is an improved version of the smaller ST200 star tracker, which is aimed at applications in pico- and nanosatellite platforms. Qualified for man-rated missions it features increased attitude determination accuracy and increased radiation tolerance. The ST400 has been qualified for man-rated missions since October 2013 and has flight heritage since 2016. Optionally AAC Clyde Space offers standard size and mission specific baffles.
The ST400 comes with a RS422 interface as default. Both our Engineering and Flight model undergo workmanship testing at different levels to make sure we can deliver with our high reliability standards.

Soundproofing your home is a luxury, but more often a necessity. This is especially true if you live in apartments and townhouses which enforce strict body corporate/strata policies regarding noise levels.
Flooring noise reduction is primarily achieved through the use of an acoustic underlay. Installers will need to lay rolls or sheets of underlayment over the subfloor before installing floating floorboards on top. Think of underlay as a layer of foam or rubber material that cushions any impacts and blocks loud noises
Acoustic engineers determine the effectiveness of flooring underlay by testing the underlay in-situ against noises. Although underlays are primarily designed for noise reduction, they can also function in a wide variety of applications:
There are two main categories of hard floor underlay; namely foam underlay and rubber underlay. Foam is by far the more affordable type of underlay because they are cheaper to manufacture and much lighter to transport, however tend to have lower performance in both comfort and noise reduction compared to rubber underlay. Furthermore, foam underlay actually flattens over time because it does not have the same density and resilience of rubber.
Gold EPE foam underlay is 3mm thick, offering a softer and comfier feel underfoot than the general silver option. This is considered non-acoustic underlay as they are not designed to reduce noise transmission.
Rubber underlay comes in many formats and thicknesses to suit your requirements. The most commonly used rubber underlays are the 3mm and 5mm options as they easily achieve a 5 star performance and are specified by strata management in Sydney. On top of noise reduction, rubber underlay also absorbs vibrations and performs much longer than foam underlay which can flatten over time.
Wavy rubber underlay takes noise reduction to the next level and can achieve a whopping 6 star acoustic performance in some conditions. Their wavy surface is designed to capture as much impact noise as possible, however is more costly to manufacture than your standard flat rubber underlay. Wavy underlay is available in 5mm and 10mm thickness.
The newest and most innovative rubber underlay combines the best properties of foam and rubber. Our composite rubber underlay achieves a slightly better performance than standard rubber of the same thickness, and yet costs less to manufacture. Furthermore, they are lighter and easier to transport or install.
The real question is whether or not the cost of purchasing underlay will significantly impact your flooring project. The price per square metre generally increases with the number of AAAC Star Ratings an underlayment has. However, this is not always the case. The prices of underlay in Sydney as of 2024 are provided below:
If you are looking to install solid timber into your floors with direct-stick to the subfloor, underlay will not be required. This scenario can arise if you do a glue-down installation of solid timber into your apartment since the strata does not allow noisy nail banging.
For example, FloorVenue stocks Marvel SPC Hybrid flooring which has a 6 star acoustic underlay pre-attached. Marvel hybrid floors can virtually be installed anywhere since it has the highest acoustic certification without the need for additional underlay. (Unless the strata demand a certain underlay thickness regardless of AAAC rating)
Noise reduction can be simplified into AAAC Star Ratings, from 1 star at the lowest up to 6 stars which is the highest. Flooring acoustic standards are determined by the National Construction Code (Previously known as Building Codes Australia) and your strata bylaws.
If acoustic underlay is required, it will be at least 4 stars or above. Most apartments, units and townhouses require a 5 star rating. Some more stringent areas will demand 6 stars or a certain thickness.
Floor underlay is a foam or rubber layer which is placed between the floorboards and subfloor. They primarily provide noise reduction from impacts and ambient noise, and are installed in apartments, townhouses and other commercial areas. Aside from acoustic protection, underlay can also act as a moisture barrier and thermal insulator.
Underlayment is mainly installed between your flooring and subfloor for noise reduction from impacts and ambient noise. This is usually a required installment in apartments, townhouses, aged care centers and other commercial areas where noise is a large consideration.
Driven by discoveries, and enabled by leaps in technology and imagination, our understanding of the universe has changed dramatically during the course of the last few decades. The fields of astronomy and astrophysics are making new connections to physics, chemistry, biology, and computer science. Based on a broad and comprehensive survey of scientific opportunities, infrastructure, and organization in a national and international context, New Worlds, New Horizons in Astronomy and Astrophysics outlines a plan for ground- and space- based astronomy and astrophysics for the decade of the 2010's.
Realizing these scientific opportunities is contingent upon maintaining and strengthening the foundations of the research enterprise including technological development, theory, computation and data handling, laboratory experiments, and human resources. New Worlds, New Horizons in Astronomy and Astrophysics proposes enhancing innovative but moderate-cost programs in space and on the ground that will enable the community to respond rapidly and flexibly to new scientific discoveries. The book recommends beginning construction on survey telescopes in space and on the ground to investigate the nature of dark energy, as well as the next generation of large ground-based giant optical telescopes and a new class of space-based gravitational observatory to observe the merging of distant black holes and precisely test theories of gravity.
New Worlds, New Horizons in Astronomy and Astrophysics recommends a balanced and executable program that will support research surrounding the most profound questions about the cosmos. The discoveries ahead will facilitate the search for habitable planets, shed light on dark energy and dark matter, and aid our understanding of the history of the universe and how the earliest stars and galaxies formed. The book is a useful resource for agencies supporting the field of astronomy and astrophysics, the Congressional committees with jurisdiction over those agencies, the scientific community, and the public.
