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

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 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.

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.

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.

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’s noise management service – Noise Sentinel – has been shortlisted for the Environmental Initiative of the Year Award at the 2013 International Tunnelling Awards.

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.

'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.

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.

Automotive expert Hyundai has expanded its testing capabilities with a Noise Vibration Harshness (NVH) simulator for benchmarking its new vehicles.

An intuitive new sound and vibration recorder lets engineers analyse their measurements on the go, using an iPad to manage data and listen to recordings. Using the portable Sonoscout system, engineers can validate recordings in real-time, to remove the risk of recording bad data and then having to repeat expensive testing.

Outdoor noise measurements are now fully supported in Brüel & Kjær’s Type 2250, 2270 and 2250L sound level meters, with a new Weather Station Kit for measuring noise and weather parameters simultaneously. Weather conditions significantly affect the propagation of sound and therefore affect measured noise levels.

Brüel & Kjær has launched the world’s first preamplifier and preamplifier/microphone combinations to withstand temperatures up to 125 degrees. The high-temperature 1706 Microphone Preamplifier enables engineers to make acoustical measurements, nearer to the sound or noise source of hot devices, such as engines and gas turbines.

Brüel & Kjær has released a new CCLD accelerometer, Type Type 4527, that can operate at a continuous temperature of 180°C, making it ideally suited for automotive powertrain uses. Type 4527 has wide dynamic, frequency and temperature ranges, making the transducer well-suited to general-purpose use. It has low sensitivity to electro-magnetic interference due to low output impedance and also features a very low noise floor. All o...

In the last 70 years, Brüel & Kjær systems have measured sound on the International Space Station and ensured all of NASA‘s Mars rovers survived the journey there. Our accelerometers have turned the Golden Gate Bridge into a giant harp and helped maintain hydroelectric generators around the world, while our world-leading microphones and hydrophones have investigated everything from submarines off Sweden to the pressure in Boeing’s wind tunn...

A Desktop Noise Vibration Harshness (NVH) Simulator has vastly improved Commercial Vehicle Group’s (CVG) customer relations and jury testing capabilities.

The roar of a car’s engine and the feel of the ride; the clear audio of a hearing aid; the drone of planes from a busy airport; the quality of a mobile phone. Sound and vibration is all around us and constantly affects our lives. Helping people solve their sound and vibration challenges is in the DNA of Brüel & Kjær - just like our iconic green instruments and our red shakers.

Brüel & Kjær has launched a software update for its hand-held analyzers - Version 4.1. Designed for the company’s 2250, 2270 and 2250 Light hand-held analyzers - and their PC software ‘Measurement Partner Suite’ - the new version 4.1 is the first feature update of Brüel & Kjær’s fourth generation (G4) hardware and software, which was launched in April 2012.

Bruel & Kjaer UK has added a new noise and vibration control training course for 2013. These acoustic requirements are imposed by more stringent regulations and can only be met by considering noise and vibration control as an integral part of the product creation process, which in turn puts tremendous pressure on the industrial design engineer.
