Bruel & Kjaer showcase vibration test tools at EIS show 2017
Visitors attending the Engineering Society’s (EIS) annual Instrumentation conference which takes place 14th March at Silverstone, can meet Bruel & Kjaer UK’s expert engineers on stand 13 and learn about the company’s latest vibration testing tools, including its 80kN shaker - the V8900.
Enhanced software upgrades signal analyser
To speed up noise and vibration data analysis for industrial machinery and vehicle manufacturers, Brüel & Kjær has launched enhanced software for its Photon signal analyser - RT Pro 7.3. The RT Pro 7.3 release provides enhanced Fast Fourier Transformation (FFT), signal analysis, 1/nth octave/acoustic analysis, modal data acquisition and swept sine measurements, making it ideal for testing acoustic and vibration in application...
Class-D amplifier revs up mobile sound quality
To meet the demand for mobile devices offering top quality sound - without sacrificing power - Nanyang Technological University (NTU) has invented an ultra-high-quality Class-D amplifier. Created by NTU’s Division of Electrical and Electronics Engineering in Singapore, the ultra-high-quality chip can tolerate more 'noise' from other components in a device, which reduces distortion so the sound quality can be significantly improved.
NVH simulator detects boom and rumble
With the latest Noise Vibration Harshness (NVH) simulator applications, non-experts and experts alike can experience the consequences of component design decisions by driving an authentic simulation. The fully immersive experience provided by a driving simulator gives a proper context to experience driving sounds in, which affects the evaluations people make.
Testing phone sound quality in noisy environments
Whether walking down a noisy street or talking on speakerphone, telephone users expect clear voice transmission. Sophisticated signal processing enhances human speech above background noise, but as there are different methods to test this capability, manufacturers cannot always be sure of the best one to use on their products.
Bruel & Kjaer buys Sound Answers
Engineering services company, Sound Answers has been acquired by Brüel & Kjær Sound & Vibration Measurement A/S consolidating itself as solution and engineering services provider. The two companies have been strategic partners for nine years and boast a long track record of joint projects.
Data acquisition system upgraded with bridge measurement
A host of upgrades has been added to Brüel & Kjær’s data acquisition and analysis system - PULSE 20. These include a versatile bridge measurement tool for industries ranging from aerospace and defence to industrial and automotive.
Simulation module added to automotive design software
Noise, vibration and harshness (NVH) simulation software from Bruel & Kjaer is now available to automotive designers as a module in Altair HyperWorks CAE design software. Automotive designers using Altair CAE software can now choose a module called Insight+, which enables them to listen to the sound a vehicle would make if it featured their virtual design.
Multiple vehicle noise tests get on track
Automotive manufacturers can now analyse noise from multiple vehicles on a single track using Brüel & Kjær’s PULSE Vehicle Pass-by Test System. Exterior noise measurements are essential for manufacturers to ensure their vehicles meet the industry standards that validate them for sale within markets such as the European Union.
Impedance meter aids aircraft test engineers
To help engineers meet increasingly strict aerospace environmental noise regulations, Brüel & Kjær has developed a lightweight, robust Portable Impedance Meter System - Type 9737. Regulations put pressure on aerospace engineers to improve liner attenuation - and this drives the need for improved acoustic impedances in jet aircraft acoustic liners
Sound source enables scale model measurements
A battery-powered speech sound source, designated the Echo Speech Source Type 4720, has been launched by Bruel & Kjaer. The device enables users to measure acoustics within any room or space, make comparisons between one room and another, validate sound systems and perform scale model measurements.
Registration now open for 2014 Sound & Vibration Conference
Registration is now open for Brüel & Kjær’s 2014 Sound & Vibration Conference, running from Tuesday 20th to Thursday 22nd May at the Hyatt Regency Schaumburg in Chicago, USA.
Acoustic and vibration course heads 2014 training calendar
Bruel & Kjaer UK 2014 training calendar, offering a range of acoustic and vibration classes, is now available. New for this year is the Acoustic & Vibration Introduction for Design & Test Engineers. This is a three-day course intended to give industrial engineers a thorough understanding of the basic concepts that are important for airborne and structure-borne noise and vibration in machinery.
Sound idea: Two-channel option hastens acoustic measurements
Brüel & Kjær has launched a two-Channel Option for its Type 2270 sound level meter to help environmental officers and consultants reduce time spent conducting multi-point acoustic measurements. It allows both channels to receive simultaneous input, from two microphones or accelerometers.
Easier environmental noise calculation, mapping and analysis
Brüel & Kjær has today announced the latest version of their Predictor-LimA environmental noise mapping software. A highly advanced system for environmental noise calculation, mapping and analysis, the Predictor-LimA Software Suite is powerful and intuitive. Ideal for both experts and non-experts, the software models a range of noise applications including industrial noise, road, rail and air traffic.
Brüel & Kjær shortlisted for the International Tunneling Awards
Brüel & Kjær’s noise management service – Noise Sentinel – has been shortlisted for the Environmental Initiative of the Year Award at the 2013 International Tunnelling Awards.
Vibration And Climate Testing Of Automotive Components
The Clemson University International Center for Automotive Research (CU-ICAR) in South Carolina, USA, is aiming to become the premier automotive and motorsports research and educational centre in the world.
Specific Sound Source Analysis For The Road Ahead
'Before-and-after' results show the difference Source Path Contribution (SPC) makes by quickly finding the contributions, from specific components, to the Noise Vibration Harshness (NVH) experienced by the driver and the significance of the NVH path.
Environmental events on the Emerald Isle
Bruel & Kjaer UK will be exhibiting at two environmental events taking place in Ireland this summer. The company’s noise specialists will be demonstrating its human vibration analyser - Type 4447 - at the National University of Ireland’s Occupational Health and Safety conference, taking place at the Galway campus on 14th and 15th June.
Hyundai refines ride quality with a desktop simulator
Automotive expert Hyundai has expanded its testing capabilities with a Noise Vibration Harshness (NVH) simulator for benchmarking its new vehicles.
