An acoustic camera generally consists of a microphone array and an optical camera whose data is simultaneously acquired to give a representation of the location of the sound sources. Acoustic imaging enables you to pin-point the exact position of any noise emitting sources both within the engine or elsewhere on the vehicle.
By David Waddington, Professor in Environmental Acoustics in the Acoustics Research Centre at the University of Salford The IOA, the University of Salford, and industry partners AcSoft and Noise Consultants Limited (NCL), are working together to prepare students for careers in airport noise. Through combination of classroom instruction, hands-on training, and real-world experience, the programme […]
Read moreWe had the pleasure of sitting down with out Technical Director, John Shelton to discuss his background and his thoughts on vibration instrumentation past and present. It depends on the application, they are both vibration transducers. Acceleration and velocity are both vibration just different descriptors of vibrations. So in that sense they are both good […]
Read moreTraceability in calibration refers to the ability to trace the measurement results of a device or instrument back to a known and internationally recognised standard. In essence, it’s a chain of comparisons that ensures the accuracy of measurements. This chain typically includes various levels, starting from the measurement instrument used, the reference standards it’s calibrated […]
Read moreWe had the pleasure of sitting down with out Technical Director, John Shelton to discuss his background and his thoughts on vibration instrumentation past and present. Within the last 5 years, what do you think have been the biggest developments in vibration instrumentation? Low power digital signal processes. You can do so much with digital […]
Read moreWe had the pleasure of sitting down with out Technical Director, John Shelton to discuss his background and his thoughts on vibration instrumentation past and present. With the B&K 2209, octave filter sets allowed you to do octave analysis, however only one octave at a time with no real time analysis. We also used an […]
Read moreWith the B&K 2209, octave filter sets allowed you to do octave analysis, however only one octave at a time with no real time analysis. We also used an integrator which screwed onto the top of a meter instead of a microphone and a switch at the top allowed you to switch between accelerometers or […]
Read moreWe had the pleasure of sitting down with out Technical Director, John Shelton to discuss his background and his thoughts on vibration instrumentation past and present. Back at university, a degree in sound and vibration and part of the course was doing measurements of sound and vibration. In my holidays I used to go back […]
Read moreConstruction sites are notorious sources of dust emissions, which can have adverse effects on both the environment and the health and safety of workers and the general public. Dust monitoring has become significantly important for the construction industry for the following reasons: The Health & Safety of Workers Construction workers are at risk of exposure to airborne […]
Read moreCalibration is a fundamental process that applies to various types of measuring instruments, ensuring their accuracy, reliability, and traceability. Calibration involves comparing the readings of an instrument to a known reference standard or a traceable measurement. Here are the key reasons why it is necessary to calibrate instruments: Accuracy and Reliability: Over time, instruments can […]
Read moreTraceable calibration refers to the process of verifying and adjusting the accuracy of a measuring instrument or device using a known reference standard that is directly traceable to a national or international measurement standard. The purpose of traceable calibration is to ensure that the instrument’s measurements are reliable and consistent, thus providing confidence in the […]
Read moreBy John Shelton, Technical Director and Chair of IOA M&I Committee Sometimes it’s difficult to keep up with the innovations in noise and vibration technology, and over the past 50 years or so, we have moved from van-sized analogue analysers to hand-held multi-function digital devices. A large part of these developments has been down to […]
Read moreTraceable calibration and UKAS calibration both aim to establish the accuracy and reliability of measuring instruments, but there are some key differences between the two. Here are some benefits of traceable calibration over UKAS calibration: Cost Traceable calibration is generally more cost-effective compared to UKAS calibration. UKAS (United Kingdom Accreditation Service) accreditation involves a more […]
