Physicomechanical Properties
Physico-mechanical properties of marble onyx generally similar to those of the majority of fine-grained marbles: the average density (bulk weight) of 2700-2900 kg / m.; Water absorption – 0,1-0,3% porosity – 0,3-0 , 95% limit prochnosi Compression – 50-110 MPa; attrition – 1,0-1,9 g / sq. see Taki indicators enable the use of onyx in an equally wide range, as the best varieties of marble. Many types of marble onyx has a high frost resistance, but to use this material for the elite exteriors of buildings in the practice of European architecture was not necessary (a few cases can be found in the U.S. and the Middle East). Considering the technological properties marble onyx, it should be noted their relatively easy workability, the ability to 'hold' at the edge of the milling and processing (due to fracturing) – in the modern production processes is overcome by reinforcement on their back side. Given the good prosvechivaemost marble onyx, for their apply transparent glues and fiberglass or glass sheet. When facing the wall (at the solution or adhesive compounds) should not get involved in thin slabs of onyx (especially if onyx light tone): mounted on the wall material at a thickness of less than 20-30 mm will be deprived of his depth and partially accept the texture and nuances of the underlying layer.

ReSound presents advanced Alera hearing family ReSound hearing aid manufacturer expands successful Alera a series of new, attractive solutions. Europe’s largest hearing fair, which will take place from 19 to 21 October in the Congress Center Nurnberg, the manufacturer will present the first real wireless listening system ReSound Alera also as mini BTE and CIC – and ear canal device. Also uses the ReSound unite mini microphone a novel component of the system presented a tiny lavalier microphone that wirelessly sends the words of a conversation partner at extreme listening conditions at the hearing. Educate yourself even more with thoughts from Peter Asaro . Thanks to unique technology, Alera guarantees its wearer to be involved in any situation and always appropriate to be able to respond. The extended family of Alera offers individual solutions for 98 percent of all hearing aids customers stores. “ReSound Alera offers solutions for a wide range of individual preferences”, so Dieter Fricke, Director of Audiology of GN hearing GmbH. It offers an excellent sound and best speech understanding for people with mild to severe hearing loss. Among the many trim levels, there is a synthesis of standard and power BTE and an IdO with paged microphone unique approaches.
All models sit comfortably and are easy to use. Optional TV, phone or audio equipment can be connected via 2.4 GHz technology wirelessly. “And with iSolate nanotech Alera has effective moisture protection from the inside and from the outside.” The hearing itself is quiet. Alera uses advanced technologies in processing incoming audio signals. The surround sound by ReSound is exactly all the processes of human hearing: each signal is digitized and lifelike models. Unwanted noise will be filtered out, adapted the signals to produce a balanced relationship ups and downs as well as volume and quiet. In addition they are stabilized, before they reach the listener. This sequence ensures exceptional speech intelligibility”, so Dieter Fricke. Spoken words sound very natural.
