DESCRIPTION:*Abstract*\n\nThe core of the seminar is a presentation and di
 scussion on psycho-acoustic effects in bells. Scott will give an introduct
 ion on bells and how they are used as musical instruments. Bill will then 
 explain a newly developed technique for visualising the complex modes of v
 ibration in bells. He will then demonstrate how these modes of vibration g
 ive a strong sensation of pitch only loosely related to the modal frequenc
 ies (the so-called strike note paradox). The seminar will include a number
  of sound demonstrations intended to investigate modes of hearing\, with d
 iscussion of who in the seminar experiences the various effects.\n\n*Biogr
 aphies*\n\nDr Scott Allan Orr is an Associate Professor of Heritage and En
 vironmental Risk at the UCL Institute for Sustainable Heritage. An enginee
 r with broad interests\, his research primarily uses data-driven approache
 s to further understanding and management of heritage\, with a particular 
 focus on the historic environment. He is also an active carillon performer
 \, composer\, and advocate\, and is currently a member of the Executive Co
 mmittee of the World Carillon Federation.\n\nDr Bill Hibbert has been rese
 arching the acoustics and history of church bells for many decades. His do
 ctorate (achieved in 2008 while working full-time in the IT industry in an
  unrelated role) was on pitch perception in church bells. He has a library
  of over 13\,000 bell recordings used for ongoing research. He has carried
  out many projects to investigate and correct tuning issues in church bell
 s. Bill is a church bellringer and also an experienced choral musician.\n\
