  • World Class Indoor Acoustics

    On January 15th, 2005, the $440 million, new Copenhagen Opera House opened with a Royal Command Performance and the tones of Carl Nielsen, Donizetti, and Rossini. Likening the sound to the gift of a Stradivarius, the Royal theatres musical director was thrilled. It is a world class acoustic he commented, that at the same time is analytical, warm and round. Every subtlety, even the very quietest, ...

  • World class acoustics on the waterfront

    This opera house balances the intimate and the very loud.” The guest conductors, opera directors, music staff and the chairman of the orchestra were equally delighted with the sound achieved. English consulting company Arup Acoustics, responsible for the design of the new opera house’s acoustics, chose ODEON modelling software for this and for many of its other major projects within ...

  • Fine-tuning acoustic isolation in buildings

    ACCIONA Infrastructure is ranked among the leading construction companies in the world - and is recognised for implementing the most advanced and innovative technology.  As research and design is vital to keep the company at the cutting edge in relation to technological developments, ACCIONA Infrastructure created a team to analyse noise and vibration. Where traditional ...

  • The Significance of Sound Diffraction Effects in Predicting Acoustics in Ancient Theatres.

    Abstract This paper examines the effect of sound diffraction in predicting sound propagation in ancient theatres. Few simulation studies to date concerning ancient theatre acoustics were conducted with diffraction effects. While sound diffraction effects in ancient theatres are known qualitatively, rarely have they been quantitatively documented. In this paper, the ancient theatre of ...

  • Canarina CUSTIC software · background noise · ambient noise pollution · commands 13

    Bitmaps and scanned maps must be loaded into memory and then adapted to the program scale (we will make use of the Scale command). The X-Axis width (meters) in the program window can be easily changed to be able to compare both images (simulation results and background maps). Then, the X-Axis width (in meters) of the imported map and the X-Axis width (in meters) of ...

  • Calibration of a 2-D morphodynamic model using water–sediment flux maps derived from an ADCP recording

    This study compared numerical simulations of the hydro-morphodynamics of a stretch of the Po River (Italy) to detailed measurements of the river's morphology and water–sediment fluxes. A survey of the 8-km-long, 250-m-wide river section, previously described in former publications, was performed using two vessels. The first was equipped with a multibeam echo sounder for bathymetry ...

  • Noise Mapping in Lille

    Lille, with a population of 1091 million inhabitants is the 4th largest agglomeration in France after Paris, Lyon, and Marseille. Situated at the heart of a network of 464 km motorways connecting six European cities (Brussels, Bonn, the Hague, London, Luxembourg and Paris), the metropolis of Lille also has the densest railway network of France after Paris. Pascal Thomas and his team of 8 ...

  • SoNoScout rides the trams

    Sound Quality and Vehicle Condition Research to evaluate sound signals inside trams has been undertaken using Brüel& Kjær binaural microphones, Time Data Recorder and PULSE data acquisition and analysis system. The tests were performed on a number of trams manufactured between 1908 and 2008, on normal town routes. Based on acoustical, spatial recordings, the initial quality ...

  • How to certify aero engines

    Aircraft Engine Noise Certification PowerJet, formed as a joint venture between Russian OAO NPO Saturn & French SNECMA (SAFRAN Group), have designed and built the new SaM146 turbofan engine selected by the Sukhoi Civil Aircraft Company to power its Superjet 100 aircraft family. The Sukhoi Superjet 100 is a medium-haul airliner developed in collaboration with Alenia Aeronautica (Italy), and ...

  • Engineers torque technology to medics

    Medical experts and sports scientists are becoming increasingly reliant on engineers as their disciplines become more and more technical. Mark Ingham looks at some of the projects his company, Sensor Technology, has helped behind the scenes. Like most rugby players I took my knees for granted until the day a twisting fall resulted in a torn anterior cruciate ligament. Fortunately these days it ...

  • Upgrading from Pellistor Gas Sensors to Infrared Technology

    In this article Andy Avenell, Crowcon’s Fixed Systems Product Manager, considers the shift towards infrared (IR) gas sensor technology in the oil and gas industry. Abstract Flammable gases and vapours can present considerable dangers in many industrial applications, none more so than the processes involved in extracting, transporting and processing oil and gas. Fast and reliable ...
