Event details

In today’s world, technology plays a big part in both development and measurement, by taking the guess work out of microphone placement and the headache out of complex algorithms. Research and technological advancements are often driven by commerce and are dictated by the potential benefits and applications. This presentation takes a look at the humble measurement microphone from a technical perspective and how it has evolved to suit particular applications. From the turbulence windscreen that dramatically improves aeroacoustic measurement results, through to the head and torso KEMAR which is at the cutting edge of headphone testing, to high frequency microphones that can even measure bats in a reverberant environment. No registration required

Speaker information

John Shelton and Emily Norman, G.R.A.S. John Shelton John is an active member of the IoA and currently chairs their instrumentation working group. He graduated in Acoustical Engineering and then attained a Masters degree in Sound & Vibration Studies from ISVR in Southampton. After a short time developing loudspeakers at Goodmans, he joined Bruel & Kjaer UK as an area sales engineer. Over the nine years that followed, he specialised in sound intensity and source location techniques, as well as managing technical sales across the UK. Two years at Brüel & Kjœr in Denmark gave him experience in VXI-based virtual instrumentation, and whetted his appetite for software measurement solutions, taking responsibility for worldwide sales & marketing. He is currently Managing Director at AcSoft and Technical Director at G.R.A.S. UK. Emily Norman Emily is the UK Sales Manager for G.R.A.S. UK and has a keen interest in Aviation, Aerospace and Automotive applications. She works very closely with clients in these sectors to ensure they get the very best solutions, prices and support. G.R.A.S. are world leaders in high precision measurement microphones and Emily has lots of fun playing with the various toys they have to offer. Her current favourite is the 67TS Turbulence Screen, with a 25dB attenuation on turbulence noise making this a very clever bit of kit. It can give better measurements and shave over £20k off the bottom line in some common automotive wind tunnel applications.
