June 2019 - Ntek

As an international manufacturer of building acoustic equipment Ntek has its own laboratory to calibrate tapping machines and sound sources. Ntek calibration laboratory works on all brands and models of equipment, offering a fast and accurate service.

As foreseen by the ISO 16283-1/2/3 standard, it is recommended to perform the revision of sound sources (dodecahedron, directional speakers, tapping machines) every 2 years. We also recommend annual calibration of the products after the purchase.

The calibration provides documented and traceable measurement accuracy and confirms that your product meets the published specifications.

TAPPING MACHINE

Verification of the impact velocity, impact rate and the dimensional measurements of the hammers according to UNI EN ISO 16283-2 and UNI EN ISO 10140 – Annex E – using the following instruments:

– test bench with structure in aluminum and serizzo marble surface;

– laser velocimeter

– a caliber and a precision scale interfaced with an industrial computer with specific post-processing software.

We’d like to highlight that all the measurements are made with our test bench don’t need to open the equipment (that could cause the voidance of the warranty).

SOUND SOURCES

UNI EN ISO 16283-1 standard also require bi-annual verification of the speaker systems to confirm compliance with this standard. Verification of dodecahedron loudspeaker directivity in accordance with ISO 16283-1, Annex A. Requires matched power amplifier.

Ntek calibration laboratory has developed a verification procedure to comply with these requirements: the dodecahedron speaker is assembled on a rotating engine in a semi-anechoic chamber through 360° and measured by several microphones in order to obtain the omnidirectionality. Measurements are calculated and compared with the specifications.

COME AND MEET US IN OUR LABORATORY!

On the just passed days, exactly from 16^th to 19^th June 2019, was held the 48th Congress and International Exposition on noise control engineering: Internoise 2019.

In the beautiful location of the Spanish capital – Madrid – at the IFEMA Palace, Ntek exhibited its entire range of building acoustics products in its latest version.

What a better overview of the world of acoustics if not Internoise 2019?

For Ntek, Internoise 2019 represented an opportunity to establish new relationships, consolidate the current ones and deal with the major exponents on the acoustics market.

A perfect opportunity to launch the new OMNI Series product on the global market: the SMART OMNI. With the power of classic OMNI 5 “speakers and the small size of an OMNI 4”, it is the most compact and powerful solution in the OMNI Series.

The considerable attendance at the Ntek booth it’s a fact that the acoustics sector is always in continuous evolution and formed by a public that goes from the nowadays well-established technicians in acoustics and university professors to an even more growing group of young engineers and technicians who approach and passionate about acoustics in all its fields.

Faced with availability and determination, this trade show gave Ntek the indispensable and fundamental direct relationship with an audience from all over the world, thus knowing their needs as well as discovering new cultures.

“At Ntek , we’re constantly working toward smart solutions to address high performance and optimize weight and portability of our products, while conserving our planet’s precious resources” said Giancarlo Sassi, Ntek General Manager.

This is the reason why Ntek revolutionized the OMNI Series. First, printing the sound sources with the innovative 3D additive manufacturing. Then, launching the brand-new SMART OMNI sound source.

The SMART OMNI sound source has been created to match the high performances of OMNI 5”, the innovative 3D printing technology and the reduced size of OMNI 4”. In just one product are included all the best technical features of OMNI Series and the high performances of the 5 inches speakers in just 9,5 Kg.

Check all the technical data on the following datasheet:

Furthermore, we have also transformed the complete OMNI Series range of products introducing a new concept of “color identification” related to the different characteristics and settings of the sound sources: check the summarized info on the OMNI SERIES in the image below.

The new OMNI Serie printed in 3D represent the real breakthrough. Production with additive technology, in addition to a greater freedom in design, guarantees with its sphericity the achievement of greater isotropy and OMNIdirectionality.

3D Printed with heat-resistant material, ensure excellent performance of the structure even after long periods of activity, without incurring in deformations due to the high temperatures reached during the operation.

Designed according to the needs and requirements, the new OMNI Series in 3D guarantee greater ergonomics: hand transport will be more comfortable thanks to the new structure of the knob, which now ensures a more comfortable and firmer grip.

Moreover, the filament used to print the OMNI Series in 3D are can also contribute to a more sustainable environment in the future. All our OMNI Series in 3D are made with a special PLA thermoplastic.

PLA (or Poly-Lactic Acid in full) is a thermoplastic which is extruded from the starch of plants, such as corn, cassava, sugarcane, cereals, or sugar beet. By being derived from biological resources this type of thermoplastic can be biodegradable under the right conditions (such as an active compost heap, with enough presence of oxygen) and therefore has a much less environmental impact than thermoplastics derived from fossil fuels.

If you want to see an example of the brand new OMNI series, you can take advantage of the Internoise Trade show in Madrid, or you can visit us in San Maurizio Canavese!

Ntek will take part to INTERNOISE 2019, the 48th International Congress and Exhibition on Noise Control Engineering at the IFEMA Palacio Municipal fair centre in Madrid (Spain).

Exactly next Monday, the exhibition area will be accessible on 17^th-19^th June 2019, so you’ll find Ntek at booth 41!

For Ntek, INTERNOISE will undoubtedly represent a great opportunity to show and make aware the public about the strong innovations and changes made to continuously improve Ntek building acoustics products range.
